I need to make a voice and video calls using SIP. I don't know, which SIP Stack choose, because application must be closed-source, but all quite good stacks are distributed under GPL license. I thinking about using JAIN - SIP stack, but I'm not sure if it is sufficiently complete and whether it can be easily implemented in Android. Anybody know a better way? I found this topic -> Looking for a SIP Stack for Android (I don't want use SIP Android API and care about free way)

Regards.

JAIN-SIP is enough for anything. If you find an unsupported use-case let me know and I will fix it.

The SIP stack inside android itself is JAIN-SIP (wrapped in different APIs). JAIN-SIP is at the core of almost all open-source Java SIP phones and servers - Jitsi, Mobicents, JAIN-SLEE uses JAIN-SIP by spec and may be 100s of other projects. No matter what you do you will probably end up using JAIN-SIP behind the scenes anyway :)
