Anyone know of a reliable router for use with SIP trunks?
We're using a cheapie, and it seems that every two weeks or so, it loses it's connection to SIP. Reboot the router and all is well.

7200S v 4.65

We've been running into this for a while.
We started pushing SonicWall TZ-105's. They will run the customer quite a bit more money, but they will have their trunks running smoothly. As a tech, you can see real time traffic and troubleshooting out of the SonicWall.

I would recommend upgrading to 4.75.

There are many items in that version that deal with SIP trunk registration and improving keep alive abilities between the system and the SIP carrier.

We use drayteck routers

never had a problem with them
