In my UMC6202 I set the GDS3710 with a fixed IP address of 192.168.0.111 as a user extension 1111 (same only for remember), I can so far I was able to register other ip phones (GVX3275) and are working without problems, but the GDS3710 is not working properly,
I can connect GDS through 192.168.0.111 by any browser, on my UCM the GDS looks as Idle and Available, but with a strange “IP and Port”: 126.96.36.199:33273, remain as Idle and Available, I can call from GDS (virtually) to another extension, but extensions can not reach the GDS.
When I reboot the GDS it shows the regular address/port: 192.168.0.1111:5060, but later change to
At UCM I am using an external host: cenaxis.no-ip.biz, but I am thinking, problem is within the GDS.
