Draytek 2850/2930

Problems with registration?

These routers seem to have very short a UDP NAT expiry ~30sec? The port was closing before the phone re-registered, causing problems with incoming calls not working (as the phone is no longer registered).

Changing the UDP timeout to 3600 on the router will help.

Firewall & Security

You will also want to set up firewall rules, as per the VoIP Firewall page.
Also see the VoIP Security page for information about securing your VoIP service.
