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.
SOLUTION:
- Could be NAT issues.
- Make sure network is configured properly and all packets reach the Softswitch.
- Do pcap capture and analyze the logs.
