Summary:

My Galaxy Nexus smartphone is now capable of receiving free voice calls and making low-cost outbound calls on a data-only mobile broadband plan. How can you send and receive calls on a smartphone without a voice plan? Android’s native SIP integration is a big help.

galaxy-nexus-sip

When I bought my unlocked Galaxy Nexus, I figured that I’d simply use the SIM card in my iPhone 4S with the handset. Instead, I pulled the T-Mobile SIM out of my Samsung Galaxy Tab. I’m glad I did because I discovered a very appealing scenario. By using the data-only SIM — which costs me $40.00 per month for unlimited texts and data — with a new Android 4.0 feature, I’ve turned the Galaxy Nexus into a VoIP phone: I can get or receive calls solely through Wi-Fi and mobile broadband networks without subscribing to a voice plan.

Native SIP support in Android 4.0

Google’s newest mobile operating system version, known as Ice Cream Sandwich, natively supports SIP accounts in the Phone dialer app. This addition of SIP support opens up a whole new world of voice possibilities. SIP, which stands for Session Initiated Protocol, unifies both voice and video over standard IP-based networks. As voice becomes data — especially in the future as LTE networks are IP-based — this means we’ll have more flexibility and features over traditional voice calls and even phone numbers.

Let me step back for one second to clarify something: SIP support on smartphones isn’t new, nor did Google “invent” anything here. I recall that some Nokia devices a few years back included native SIP support in both the Symbian and Maemo platforms. In addition, there are a number of third-party SIP-based VoIP apps available for both iOS and Android. Google has simply integrated SIP support into the platform.

Wi-Fi and 3G are generally fine for voice

Having said that, I’m glad they did. As I was using the Nexus all weekend long (see my first video impressions here), I was still carrying my iPhone 4S, which has my primary phone number. Finding the SIP support and configuration options within the Android 4.0 Phone settings got me thinking more about VoIP. It also didn’t hurt that in my local area, I’m seeing nearly 10 Mbps download speeds on T-Mobile’s HSPA+ network. Standard voice calls use far less bandwidth — around 12 Kbps — while even new wideband audio codecs used for higher quality sound top out around 64 Kbps. So, VoIP over Wi-Fi and 3G ought to be just fine for the most part and shouldn’t do too much damage to a capped data plan.

The SIP setup

There are a number of VoIP companies that support SIP, so I did some research over the weekend and settled on Callcentric for now. There was no charge to get a SIP account, which enabled VoIP to VoIP calls on my Galaxy Nexus after I configured the Phone app. Taking things one step further, I signed up with Callcentric to provide me a local phone number for $2.95 per month. With that, I can receive incoming phone calls at no charge: These can originate from any phone — mobile or landline — just like a traditional call. But while the phone may start on a cell network or old copper line, it gets routed as data to my handset.

 

That’s all well and good, but to be honest, I don’t want to give my contacts yet another number. Enter Google Voice, which uses the customized phone number I hand out to everyone. I added my Callcentric phone number to Google Voice and now all incoming calls to my main number ring my Galaxy Nexus at no charge. They also ring all of my other phones, making for a jarring experience when I actually get a call!

So now I have free incoming calls coming to the Nexus and its data-only SIM card. I tested a 20 minute Wi-Fi call with Andy Abramson, a VoIP guru, and the call quality was superb. Testing calls over HSPA+ to my son were also great, but of course, will vary based on coverage and other factors.

Free incoming and cheap outgoing calls

But if I stopped there, I would only be able to make outbound calls to other SIP users. Again, Callcentric had a solution. While it sells unlimited voice plans for $19.99 a month, I make few outbound calls, so I opted for the no monthly charge, pay as you go calling plan. By adding a minimum $5 credit to my Callcentric account, I can now make calls to any phone — a landline or a cellular phone — from my Nexus over the data line. The cost for calling in the U.S.? $0.019 per minute. Given my limited outbound calling, that $5 ought to last me several months.

There are a number of ways to get all of this working, but this was my first effort and I’m generally happy so far. The only downside right now is that outgoing calls show my Callcentric phone number on the recipient’s phone and I’d rather have my Google Voice number appear. Some third-party SIP clients and services allow for number “spoofing” to make this happen, so I may yet change my setup. Ideally, I’d like to see Google add both SIP support and number spoofing to Google Voice.

Data for the win!

Again, I had planned to switch my AT&T SIM between the Nexus and iPhone 4S, but I think this solution is better. I don’t need to swap SIMs and incoming calls will ring both phones. The data-only SIM without a voice calling plan requirement is about half the cost of a traditional voice and data plan, even with the $2.50 a month I’m paying for the Callcentric phone number. And my Samsung Galaxy Tab — which is effectively a Wi-Fi tablet — can still be taken everywhere because its SIM card can be used with the portable hotspot feature of the Galaxy Nexus. It’s a win all around for me.

My deeper dive into SIP and mobile VoIP is far from over, though. I’ll continue to look at alternative options and third-party clients. My next step is a chat with the folks at Counterpath, which offers Bria, a VoIP/SIP client, for both iPhone/iPad and Android devices. I’ll share the results of that discussion in a follow-on post within the next day or two. In the meantime, I’ll be enjoying voice calls on my data-centric Galaxy Nexus!

  32. SIP support was added to android in Gingerbread.

    Internet calling

    The user can make voice calls over the internet to other users who have SIP accounts. The user can add an internet calling number (a SIP address) to any Contact and can initiate a call from Quick Contact or Dialer. To use internet calling, the user must create an account at the SIP provider of their choice — SIP accounts are not provided as part of the internet calling feature. Additionally, support for the platform’s SIP and internet calling features on specific devices is determined by their manufacturers and associated carriers.

      That is correct. Nobody ever knew it because the only way you could use it was with a Nexus device or custom ROM. Same as Goole Talk Video Chat. Thank the carriers and OEMs that seem to think custom skins are the only way to differentiate rather than making quality, unique hardware.

      Share
    2. Yup, I completely missed it until someone on Google+ mentioned it me. Thanks for the catch – I verified it on my old Nexus One and see the SIP settings, so I’ll correct the story. Thx!

      Share
      1. I’ve got this feature turned on and using it on Gingerbread in a Nexus One, but I’m not allowed to use it over Mobile data plan, only over Wi-Fi.. How could you enable this? Thanks!!

        Share
        1. Interesting (and not good, of course). Do you know what’s or who is blocking it? It almost sounds like your carrier or plan somehow, so I’m not sure how to get around it, although I’ll fire up my old Nexus One when I get a chance to see if there’s a setting in there to address this.

          Share
      2. (I don’t know why, but I couldn’t reply to your newest comment)
        It’s not my carrier who’s blocking it, it’s just the phone who does not try to reach the server. It’s on the settings, where I can choose whether to use SIP it’s clearly written “only wi-fi”. I can choose between authomatic or manual setting and if to register for incomming calls.. but no way to use it over 3G. Maybe it’s a matter of gingerbread or ICS or just the hard of the NxOne that it’s to slow..

  43. Wouldn’t it be a whole lot simpler if Google just allowed Google Voice to work on Android phones?

    Share
    1. seriously! I’ve been waiting for Google to do something with their purchase of
      Gizmo(5). You used to be able to use Gizmo to setup VOIP but they dropped it. . .

      I currently have gMail as my home VOIP–works great.

      However, isn’t using VOIP over carrier data illegal? Don’t most carriers have some clause the you won’t do such things?

      Share
      1. It’s not illegal, but the carriers would be most upset with Google if they allowed VoIP. It’s inevitable, as there will be some virtual mobile operator using Lightsquared’s or maybe even Sprint’s network to offer a pure IP smartphone, but the carriers want to extract as much profit from the incredibly low cost of call routing for as long as they can.

        Share
  44. Correct me if I’m mistaken, but can’t you use Google Voice to make free outbound calls?

    Share
    1. That’s correct – you could have Google Voice call a telephone number (DID) supplied by IPKall and get free outbound and inbound calls to US/Canadian land lines, plus really cheap calls to overseas numbers (I know Canada’s not our 51st state, by the way).

      Share
    2. Not by GV alone, but as Paul mentions there are ways to do with another service. I actually got a phone number from IPKall before I found Callcentric, but opted to use the latter solution, at least for now.

    If you have a Google Voice account, you can do this without a separate SIP provider (thus REALLY FREE) by making a one-time purchase of the GrooVeIP app (market link: https://market.android.com/details?id=com.gvoip) for $4.99. It allows you to login to your Google Voice account and make & receive calls.

    I’ve been using this over on WiFi only (as I have a voice + data account on tmous), but it also works over 3g + 4g.

    Just a suggestion.

    – robbie

    Share
    1. Kevin – if you try this please let us know your opinion on GrooVeIP … sounds interesting.

      Share
    2. Do you have to give your gmail login/password to GrooveIP to get that to work?

      Share
      1. This is my concern! It appears you do, and to put it mildly, my GMail account is the key to my identity…

        Share
      2. If you set up 2-Factor authentication with your Google account, you can create a one-time password for Groove that will only give that program access to your account and can easily be turned off.

        Share
    3. Yup, Robbie, GrooveIP is on my “must see” list too; Andy mentioned to me during our test call yesterday. Great suggestion: thx!

    Really have them just finally integrate GVoice to Android properly and add this capability native.
    Ohh BTW also finally have Canada enjoy GVoice … talk about lack of focus for Google. Seriously, stop this nonsense with the other projects and provide value with the those that your customers really waiting for (FOR YEARS).

    1. VoIP uses next to no bandwidth (12 Kbps in the case mentioned here), so you would have to be talking a lot to go over even a 1 GB data limit (that would take talking non-stop for about 8 days).

  91. T-Mobile also offers a “monthly 4G” plan with is 5GB of data, unlimited texts and 100 minutes of voice calls for $35 without a contract.

    Share
    1. Yup, I think its actually $30 a month, but you’re correct; there is a low priced plan with data and few voice minutes. I bought my Tab on contract so I’m sticking with the $40 plan for now. The ETF at this point is more than the $10 a month savings. ;)

      Share
    2. Can you be a bit more precise about which plan you are referring to, and where you bought it? I called my local tmo store and they did not know of such a plan, but thought perhaps a partner of tmo’s was offering it.

      Thank you

      Share
      1. That $30 T-mobile plan (100min 5gb data unlim txt)
        Is a walmart exclusive plan that goes through T-Mobile, you need to buy a activation sim kit from amazon for $2 or so, then activate it @ tmobile’s website (prepaid sectiion) when it asks which plan scroll down to the 100 min unlimited data & txt plan for $30.

        NOTE: You CANNOT change your voicemail forwarding on T-mobile prepaid to Google Voice Voicemail. You still can get it working but it will give you an error when you activate the google voice app. I was able to just get people to call my gvoice number then forward that number to my T-mobile number.

        Couple other issues with T-mo prepaid, no national data roaming, not that big of a deal but if you travel a lot in rural areas it could be annoying to some people. Also if you already have a T-Mobile number, you can’t keep it, you have to get a NEW sim activation kit and a new phone number.

        Sorry for any typos and bad grammar, im in a rush and wanted to provide this info in case someone is looking in to getting this plan.

        Share
      2. Forgot to add that no one at T-mobile can set you up with this plan, you have to buy a new phone, or sim activation kit at walmart, or buy a cheap sim activation kit from amazon ($2 or so) and activate it on T-Mobile’s website.

        Share
      3. I was able to get my locl tmo store to give me a sim card and then active me online by asking specifically for the $30 unlimited data 100 minute plan. The rep had done this before for several other people. Details: http://blog.bn.ee/2012/01/05/ice-cream-sandwich-for-30month/

  92. I imagine that doing this would exclude features such as SMS and MMS?

    Share
    1. It depends on what’s included on your data plan of course, but mine has unlimited messaging/MMS. I just tested both from the Nexus to my iPhone 4S and they worked fine.

  106. >>The only downside right now is that outgoing calls show my Callcentric phone number on the recipient’s phone and I’d rather have my Google Voice number appear.<<
    Although it isn't SIP compliant, Skype does allow you to set the number Kevin [... you probably knew that :) ].

    1. Yup, Alex, that came yup during the weekend research as well. Choosing to integrate SkypeOut with this solution would do the trick for caller ID. Appreciate your mention of it! :)

      1. I configured my gnex to have internet calling from Callcentric. The outbound calls were showing different number. Then I contacted costumer service and they asked me verify my phone number. I provided google voice number, now all out-bound call is showing my google voice number.

    Im currently doing this on my phone, and yeah, its cheaper, but its not all its cracked up to be. SIP support is buggy over 3G and it often takes 2 or more tries to get a call all the way through. And the delay is awful, much worse than regular cell phone calls.

    Is it worth the $30 a month im saving? Absolutely. But this is not a perfect dropin replacement.-

  125. I’ve been doing this for a while with a seperate SIP app (3cx) and a data only sim in my Nexus S and it works great (except when the app crashes). I got an incoming number for $1 a month and calls cost $0.0049 which is pretty hard to beat. Hopefully I can upgrade to ice cream sandwich for native SIP asuppoer.

    1. Nice solution Dave! That’s a sweet rate for outgoing calls. What’s so nice about this is that we consumers gain back a little control and can choose between various providers & rates.

  136. I had to root my t-mobile phone and install cyanogenmod to get the native Gingerbread SIP/VOIP support. Get the google voice # anyway and forward to your callcentric DID. The google voicemail + transcription is well worth it. Don’t turn on your callcentric voicemail, and just pass-out your GV number to people.

    I’ve bought DID numbers in the countries of several family members/friends, all forwarded to my callcentric SIP… it’s cool! =D

    Share
    1. Jason, I’m hearing from Android owners that most carriers aren’t keeping the native SIP stuff in Android 2.3. That’s a bummer, although I suppose I shouldn’t be surprised. Glad I went with another Nexus. Thanks!

    If you really want to get fancy, you could also use the opensource, SIP-powered Phono Javascript Phone API to build native Android and iOS VoIP apps that can place and receive SIP calls with the Tropo cloud communications API and platform to create conferencing, recording, call transfer, or speech recognition apps similar to SIRI!

  149. I don’t make many outgoing calls either. My solution was to pop in a voice-only prepaid SIM in my Touch Pro 2 for calls. $100 buys me 1150 minutes good for a whole year, or about $8.33/month. Data was taken care of thanks to a 3G/4G hotspot providing unlimited data for $45/month.

    I admit the SIP/VoiP route is very attractive, as it eliminates carrying a separate hotspot device for data. My problem is that if I get a data-only SIM, I’m severely capped since AT&T and TMO no longer offer an unlimited plan. Considering I can easily eat through 30GB/month, paying triple-digit overage charges is no fun!

    Share
  150. I saw a mention of the N900 (Maemo), it came hardwired with Skype (In and Out) and also does Google Talk voice and video calls, over 3G and wifi.

    I have a Galaxy Tab 10.1 Wifi only, it runs Gtalk and Skype over Wifi (Gtalk is better quality) and I can run calls via the N900 using Bluetooth tethering (yes, it works) – hooking into the N900′s mobile broadband, if needed.

    All for a $AUD29 SIM… the telcos will hate it… but meh.

    ok not trying to troll…but I’ve seriously been considering btw the 4s, sgs2 & the galaxy nexus, and it’s things like these that make me fearful of Android and want to stay w/ iOS…I’m a geek (did Windows Mobile before iOS, mod a tablet pc forum) but I don’t feel I should have to go through all of this when there’s Talkatone on iOS (input my GV account info & done), and I’ve used GrooveIP on Android (Samsung Galaxy S on Froyo), and didn’t find the call quality that good.

  179. Another vote for GrooveIP here. I tried it for awhile with a data-only plan and found that call quality suffered on 3G to where it was pretty much not usable. However, I use it all the time over wifi and think it’s great. I can put my SIM in my HD7 but still take calls on my Sensation because of GrooveIP.

    Kevin, I would be interested to hear how GroveIP works on your GN with a data-only SIM and in an area that is HSPA+.

  185. I have a mobile voip setup too;

    Nexus One with a data only plan form T-Mobile USA ($30/month)
    Google Voice number (free)
    IPComms for DID (free)
    Sipsorcery to manage sip accounts and connections (free)
    Csipsimple – an android sip client/softphone (free)

    So, google voice forwards my calls to my IPCOmms number. IPComms forwards my calls to my sipsorcery account :username@sipsorcery.com. I receive and make calls with csipsimple (look for it in the andriod market). That is for incoming calls.

    For outgoing, sipsorcery gives you the ability to connect to the google voice callback API. So with a ‘dial plan’, you can make regular phone calls via sip and it is all seamless. The only thing I pay for here is my data connection with t-mobile.

    http://code.google.com/p/google-voice-sipsorcery-dialplans/w/list

    Item 8, on that list works best for me. As some of you guys said before, IPKall will give you free DID too. They have outages too often so I left them for IPCOmms. Sipgate does this same trick in a slightly different way (you actually have to register your sipgate sip account in sipsorcery)

    About csipsimple, I can say that it is the best sip client I have used ever on any platform including those on regular PCs. I prefer it to the native sip client on my rooted nexus one running CM7 because, you can customize it heavily to meet your needs. It also supports NAT and ICE which helps with one way sound issues sometimes. It also has echo cancellation. The developer is very responsive to help with issues. Most times, it is because you’ve selected some wrong settings. It is also pre-configured for most of the common sip providers. So you basically enter your username, password, and server.
    I do not know how well the sip client in Ice cream sandwich (4.0.1) works just yet (b’cos I don’t have a galaxy nexus) but once the roms come out, i’ll test it to see how it compares to csipsimple.

    Finally, I bought and used GrooveIP for a while. It was ok. I’ll give it a 5 out of 10 though because the lag was very noticeable especially on 3G. Calls were not as clear on both wifi and 3G. It also seemed to take my processor a lot too. I guess our best solution for google to give a google voice a sip end point. But as you’ve all noted, that won’t make the Telcos happy. I think eventually, it will happen though. VOIP killed home phones in the form of vonage, etc. It will happen on mobile phone too.
