Hi All, Does anyone have any issues with Mikrotik dropping any SIP traffic after a 10min active call happens? This happens constantly, just wondering what I have to tweak to get this resolved. SIP ALG is off. Firmware version is 6.34.4 Thanks Marius ________________________________ Thinking of updating your phone system?

Hi Marius, Sounds like it might be related connection tracking timing out - check timeout values for UDP connections under 'ip -> firewall -> connection tracking' If that's what is happening, then you probably have NAT involved in some way, which is always problematic for udp type sessions especially when there are multiple SIP clients on the LAN all connecting to remote SIP server. The gist of what happens is that the source address of each outbound session is selected at random by the NAT connection tracking - when the UDP connection times out, it will probably be renewed with a different source address. You can also potentially work around the issue by reducing re-register times on the SIP client devices - so long as re-register is less than the UDP time-out settings on connection tracking, then you should get a stable session going ;) Cheers! Mike.

What Mike said, plus: One to one static NAT works much better than NAPT for this, UDP then bypasses the router and the association's can be retained by the server itself. Had to do this for our VC software.
