IP Dect Stand over VPN

[inlagian]

Hi, does anyone have experience of IP Dect stands over a VPN, i.e. does anyone have an example of the required configuration?

We have it working perfectly well locally on the LAN but move to a VPN (which is working - can ping subnets and pass data) and it fails to register.

Routers are Draytek Vigor 2820, haven't turned off SIP alg as yet. Ports forwarded on router and no ports being blocked by ISP.

All suggestions gratefully received.

Thanks

Assuming I'm following along with you...what model phone?

5330

A wireshark trace shows an icmp port unreachable message so it's a router config issue rather than a phone config.

Final update

Firewall on the 5000 set to reject requests to port 5060 hence the wireshark 'port unreachable'. I was looking at the trace from the wrong direction and so misinterpreted what it was telling me.

Solution: browse to the phone system, in diagnostics under firewall, allow 5060 from the LAN.
