Asterisk PBX Calls cuts of Calls at 32nd second.

This problem seems to be a NAT issue, call is terminated at before 60 seconds, I not an Adroid developer but I cant check you Asterisk nat settings, also defining an stun server to your sip client could fix the issue

Hi, i am php developer, with more the 8 years the experiencie with asterisk and voip, i have experiencie with nat problems .

You may not want to hire me, but I would like to help you anyway. Please check these settings. If you have calls cutting off after 32 seconds, then you most likely have a SIP dialogue problem, where something hasn't been acknowledged properly for Android. There's a round trip timer timer called the T1 timer (normally 500ms) and the timeout is after 64 intervals. Each interval is 500ms, so 64 * 500ms = 32 seconds. Find that setting and ensure it is set properly. Hope this helps, Dan
