I feel like I have looked everywhere, can't find any answers to the problem. I need a SIP client for Android that works with the 3CX BPX phone system. I have tried SipDroid and SipAgent and no dice on either of those. Can't find any articles on how the SIP clients should be configured either. Has anyone found a client that works with 3CX + Android? If so what was it and was it compatible with 1.5, 2.0, 2.1?
