Registered endpoinds can call, unregistered cannot

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hello All,
 
I have a weird problem.
I have a tandberg MXP 990 and Polycom QDX 6000 system, registered at our gnugk (192.168.0.1) connected to a Palo Alto firewall that is configured to do a 1 on 1 portforward (NAT) from 123.123.123.4 to 192.168.0.1.
If i connect from Home with Polycom PVX 8.02 to the external IP 123.123.123.4 it succesfully register and i can make calls to all endpoints.
I can also call out to endpoints not registered to the gatekeeper (IP Call)  from all endpoints.
 
However if i unregister from gnugk and try to make a call 0183@xxxxxxxxxxxxx i get a no route to destination.
 
Below is the output of a level 4 trace:
