I am planning to develop an iOS application where I need to use VOIP services. I found Liblinphone which is one such open source API for VOIP.
My requirements:
- Making voice call & receiving
- Making video calls & receiving
- Making voice call conferences.
Are these all possible with Liblinphone? Are there any other opensource VOIP libraries for achieving this better than Liblinphone?
Any help and tutorial links are a big helpfor me.
