Hi,

I'm using 376.48_3 on RT-N16 and have some problems with my SIP adapter. Sometimes when my Internet provider resets PPPoE connection, SIP adapted doesn't reconnect. Router reboot solves the problem but it is bad idea. I googled a lot and found that it is most likely because conntrack table keeps obsolete records and I have to reset conntrack table after PPPoE re-connects. As far as I understood, the best way to do that is to add conntrack table clear procedure to wan-start and even found that
conntrack -F
do that but there is no conntrack-tools in the firmware. How can I do it without conntrack-tools? Or maybe you know another way to solve the problem - please write it. I played a lot with UDP Timeout: Assured and UDP Timeout: Unreplied as it was suggested in some forums but didn't get any results.

Thank you in advance.
 
What I'm doing for now:
as my ISP resets PPPoE connection every 24 hours, I've created cron job thru init-start to restart router every day at 2AM plus I've added SIP adapter restart procedure to wan-start. It works perfect in most cases but sometimes ISP resets connection earler than in 24 hours and I have the problem described in the initial post in that case.

Does anyone have such problem with SIP adapter/phone? How do you solve it?
