This is a method to turn your n7 (or any other tablet) into a fully fledged soft phone with FREE incoming and outgoing calls all over the us.

This has the benefit over groove ip / sipdroid in that it still allows you to receive calls in Gmail. In addition, I found the call quality /delay in groove ip to be AWFUL.. This call quality is on par or better than tmobile wifi calling.

-----
This guide presupposes that you use Google voice. This will work on ANY ROM as long as it has been deodexed.

I know it sounds complicated, but it's really pretty simple if you follow the steps... And pretty foolproof. It took me about 15minutes from beginning to end to do all of this.

Step one: configure incoming:
1) set up a free SIP account with Callcentric.com . Once it is set up, click to 'add features' and add a free incoming number(note: if you don't want to pay for 911 services, you have to say that you're not in the US).
3) setup a sip app on your tablet (i like csipsimple.... Free in the play store) and connect it to your callcentric, account (user name is your callcentric sip number... Should start with 1777)
4) go to Google voice on your computer, go to settings, and add a new number. Add the number you were given by Callcentric (the phone number, not the 1777 number) . It will call and confirm you. It should ring through to your tablet! You now will receive incoming calls to your tablet! (note: if it can't 'hear' the numbers you are dialing, hang up, increase the volume on your tablet, and try again)


Now, let's get you set up for outgoing calls.
1) download voice+ from the play store and connect it to your Google voice account.
2) download exdialer from the play store (dialer one doesn't work... I don't know why)

Now you have two options. You can:

A) go here and use this nifty utility to modify your ROM for you http://forum.xda-developers.com/showthread.php?t=1877891 (thanks Mateorod!)

or B) modify your framework-res.apk to make the tablet think that it is voice capable so that voice+ will be triggered when you make a call (this is what the above utility does for you).

1) download the framework-res editor that is attached here and unzip it
2) copy your framework-res.apk from your ROM (found in the /system/framework folder) and put it in the 'place-framework-res-here' folder
3) double click on 'run me' and decompile your framework-res
4) in the 'files-to-edit' folder, click on framework-res.apk>res>values>bools (edit the bools.xml file)
5) find the line for 'voice capable' and change 'false' to 'true'. save and close the file
6) in the framework Flasher that you opened in step 3, choose '2' and compile a new apk
7) choose option '3' and sign the apk.
8) choose option 4 and create an update.zip
9)flash the update.zip that you made
10) click 'thank' for my help in making this guide ;)

Note: if you are getting an error about "echo off", you probably don't have java jre installed. Install that, and you should be good to go.

Done! You now have a fully working soft phone!

Hope this is useful to others...

Flash this in recovery, and it will enable "voice capable" in your framework-res.apk, which will allow you to use google voice callback.

In addition, it will allow you to configure a sip set up using the native implementation (you will need to change your dpi to 320 for it to show up, but you can switch it back afterwards)

Hope this helps!

(same as the file attached)


Note: this was based on the framework-res.apk from the AOKP nightly from 8/15. Flash at your own risk. If it does work for you on another ROM, please post here and let us know! If it fails and your tablet won't boot, just flash another copy of your ROM and it will fix the change)

Tried this and got a boot-loop

What Rom are you on ?

Pull your framework-res.apk from /system/framework and I'll make one for you.

Can I just replace the framework.apk with mine and then flash the zip using my apk? Or is there more to it?

Forgive my ignorance, but which folder is that file in? I was just going to make a copy with Root Explorer.

Thanks for the zip. I was love until I found out I could no longer receive calls. I did a factory reset and I can receive calls once again now that I'm back on grooveip. Are you having any problems receiving calls? If not can you share you're setup

Hi!
I can't seem to recompile the APK I get this error:
Code:
For additional info, see: http://code.google.com/p/android-apktool/

ECHO is off.
An error has occurred. Check the log for more info.
ECHO is off.

Press any key to continue . . .

And in the LogSimple file it just says this:

Code:
---------------------------------------------------------------------

Is this a know bug and is there a fix?
Thanks!

    Ok, I managed to obtain a proper framework-res.apk for JB 4.2.1 (with voice call enable :):) ... but I had to manually edit the binary file resources.arsc!
    - So, I first replaced the aapt.exe and apktool.jar provided by the OP by the ones at this link:
    http://forum.xda-developers.com/showpost.php?p=34806981&postcount=265.
    and followed the first few step provided by the OP.
    - Then I followed the recipe provided in the following post and edited the original apk and to obtain the modded one:
    http://forum.xda-developers.com/showthread.php?t=1823223

    The final apk is notably smaller than the original one, but is is due to the compression.

    I can perform call directly with stock Dialer (no need of ExDialer) and the quality is way better than with GrooveIP or Talkatone.

    I had to go this way since we don't have access (yet) to Google Voice in Canada!

    Last, it seems (I have to try) that SIP account can be added to the stock dialer by changing the DPI to 320 in build.prop file, ie this post (for the Nexus 7 3G):
    http://forum.xda-developers.com/showthread.php?p=34752693&highlight=320#post34752693

    the new apktool is here :
    http://www.androidpolice.com/2012/1...-2-support-the-latest-smalibaksmali-bugfixes/
    https://code.google.com/p/android-apktool/

    so I think (not tried yet) that we can simply follow the op and just replace the aapt.exe and apktool.jarwith the updated one.

    Working for stock roms, no mod required.

    This info should be added to OP in my opinion to give alternatives and info to new comers, those on stock/odexed roms etc. Just insert a note after step 1 setting up csip, then after putting this info in, leave the framework mod info for those with deodexed roms and whom want a traditional dialer. -- People on stock and odexed Roms can simply setup the csip for incoming calls and use this handy posters advice. You won't get a "traditional" style dialer but the functionality is all there, no need for dialers and voice+. Just the regular Google voice app and you're off and running making and receiving calls plus for those who don't know yet you can also text with the Google voice app and service. You can replace his IPKall reference with whatever phone number your SIP service of choice has provided you. Works like a charm for me on stock 4.2. Thanks 32str8 (thank his post on page ten)!
    For those of you who want to use a stock ROM and do not want to mess with the framework apk or are having a hard time with it (it is a bit tricky/annoying). Set up the tablet for incoming calls as described in the initial post and then if you want to make an outgoing call open up your Google voice app and use the click to call icon (phone icon) type in the number to call in the appropriate area (if you have your contacts in Google voice you can use #'s or letters to recall the list to select). In the "phone to call with" area make sure your IPKall number is selected then hit connect. Wait, your Nexus 7 will ring, answer it and it will place the call through with your Google voice number as the id seen on the other end. Nice and easy. All of the Gmail connectivity stays in tact and your call log is accessible form your Google voice account/app. Hope that helps.

    Just wondering if somebody had chance with this mod with JB >=4.2 ?

    The apktool provided in the OP does not work, so I found an apktool.jar and aapt.exe that are working correctly with JB >=4.2 and replaced the file provided by the OP (http://forum.xda-developers.com/showpost.php?p=34806981&postcount=265).

    Then it worked perfectly to decompile/compile/sign/...
    However, the framework-res.apk created is only ~5.8MB while the original one is 9.4MB ....!I when ahead and applied the created patch.
    It some what worked since phone functionality appeared, however, I did not manage to achieve a call (with Dialer I was reaching the Voice+ plus panel where it tells you that if it does not ring in 5 s you can cancel ... ExDialer was stopping the call before that panel).
    Also my system had a weird behavior and I had two "Android system" processes running (is that normal ?) so I restored to my original system.


    Anyone as tried it with > 4.2


    When doing similar edits using apktool to enable native sip stack on sgsii it was important to NOT allow compression when repacking the apk. I recall something about a pack only option.
