SIP - Stale SIP Session are we the only....

RouterOS General

I have a question for the vast amount of companies using Mikrotik Routers.
Are we the only company experiencing issues with so cold “stale SIP sessions”. We will experience an issue on some routers where the client incoming out outgoing VoIP calls just stop working. Upon further investigation we will find that under the connection tracking table the sessions will still be there once this is cleared and the SIP registration gets refreshed the system will work as expected.

The SIP “helper” under service ports we keep disabled as this just caused one-way audio or other funny issues with VoIP. Are we missing something here or how is other guys experiencing this using mikrotik CPE equipment.

Might is just be that the link is not stable and therefore causing the registration to drop and because the timeout is set so high it never refreshes the session?

Please advise if anyone has any use full info regarding this.

I had a similar problem a week ago. It was caused by a loop I created in VOIP traffic.

When registering with VOIP provider the counter starts for 3 minutes. To receive call I have a catcher that accept calls in the timeout period.

To test shorten the re-registering time on your VOIP device or lengthen the time out time in connection tracking for UDP…I think stream.
