A- I have a linphone based ios VOIP app. I want to modify it by:
1- When first downloading and installing app and registering it does not work from the first time.
2- Reset Ringtone to use phone default ringtone
3- Change audio selection to PCMU only ( only one codec must be selected now several).
4- Replace wherever showing Linphone with VoiceHi ( now when receiving or miss call it says Linphone want to change to VoiceHi).
B- Build it using my existing source code.
C- upload it to Apple Store.
D- Give Source code
