Switch may not be responding to the SIP re-INVITE.

Some providers perform a SIP re-INVITE every 15 minutes for any active calls. It's a way of checking if the call is indeed still active. If an appropriate 200 OK is not received back, they disconnect the call.

POSSIBLE SOLUTIONS:

Refuse SIP re-invites: In the general section in /etc/asterisk/sip.conf: session-timers=refuse


Could be NAT issues:

  • Make sure network is configured properly and all packets reach the Softswitch.
  • Do pcap capture and analyze the logs.
