KX-TDA30 disconnects forwarded calls randomly

[Paszczakojad]

Hi

I have set up call forwarding on several I coming Call Distribution groups. It works in general, but calls are disconnected after a random period of time (like 1 or 3 minutes). Sometimes calls aren’t disconnected even after 15 minutes. The CO-to-CO call duration is set to 60 min. I tried to use different operators for outgoing calls and the only difference I noticed is that when forwarding to an analog CO line after that random disconnection the receiving party is still connected to the PBX for a few seconds and hears 3 beeps.

Do you have any ideas?

What about Extension to CO duration?.

I can't check it now, but the calls from extension to CO are never disconnected. Only forwarded calls that come from CO and are redirected to CO. And the redirection is on the ICD group level, not on the extension itself.
