Wifi calling discovery

Ive been looking around and researching on how to get wifi calling on AOSP roms. I have made what I believe to be a big discovery. T-mobile now uses IMS for newer android phones, which is UMA/sip etc. I decompiled the ims-service.apk from the stock DLJA rom. I found an XML that contains the settings to use the service! You can get the IMS installer from here http://code.google.com/p/the-ims-ope...t-for-android/

I put the settings into the app and tried connecting but it came up with ER05, invalid SIM card. I googled that and it I get leads to saying that the sim isn't authenticated for WIFI calling. I know that it is, because it works fine on stock roms. I've also attached a logcat of me attempting to connect. I've attempted to change some of the info of the strings to reflect my personal phone number but that did not change anything.

Great find! Wifi calling is one of my favorite features.

This isn't a suitable thread for "developer discussion." It also doesn't even mention which phone it's for, but based on "DLJA", I'm guessing it's for the SGS3, so it should be moved to the tmobile sgs3 sections.

Take care

Re: Wifi calling discovery
Nice find buddy! Maybe this will go somewhere. Wifi calling is the ONLY feature I miss from touchjizz.

Re: Wifi calling discovery
Anyone could have told you it's IMS. I don't get what you "discovered".

Sounds like what he discovered was the xml file with the config in it, but it seems like there must be more to it than that, since it didn't work.

Correct, I found the settings for the application to work, just need to figure out how to fix the sim authentication error. I was hoping someone would be able to chime in and give some advice

So I took part in a survey this morning sent from T-Mobile. They had some very interesting questions pertaining to Wi-Fi Calling and AOSP ROMS, specifically if I was running on a rooted device, and if I was able to get Wi-Fi calling enabled on whatever ROM I was using. They had other questions about Wi-Fi Calling and how much I would use it, etc...Apparently they're recognizing the community and are starting to ask the right questions. I like this line of thinking!
