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.

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:
