Have been reading a lot about Asterisk and in forums before thought to post a problem too on this
Asterisk Server setup is little complicated. Hope, below mentioned describes the best.
Endpoints first connect to a VPN Server with IP ranges from (172.16.0.0/16), that VPN Server makes a NAT to connect to our internal servers like 192.168.15.8 (ranges from 192.168.15.0/24). Here whenever endpoint tries to connect to asterisk server (192.168.15.221), the communication flows via VPN Server ( 192.168.15.8), that means whenever i check connection made to Asterisk server ( all clients connect with same IP (of VPN Server - 192.168.15.8) but, with different port.) like
192.168.15.8:28273 ==> 192.168.15.221
Endpoints get connected to Asterisk server (without a problem). but the call doesn’t happen/flow nor even the ring.pjsip logger.txt (12.6 KB)
I have also attached pjsip logger. Hope, it is described well.
