Greetings,
I have a client that reports calls are dropping after 15 minutes. My first thought was ensure SIP ALG has been disabled in their Sonicwall. I have confirmed this has been done. Firewall checker passes and does not detect SIP ALG. Ports seem to be matching so I believe the Sonicwall is configured correctly. The odd thing is, not every call longer than 15 minutes is being dropped. Example: I have users that have successfully made 20+ minute phone calls without issue.
It seems that the issue is mainly affecting outbound calls. Inbound do not show the issue. When I check the call reports, some dropped calls show they were terminated by the user, and some show the call is dropped by the callee.
Any suggestions for what I can check?
