FXO: CCM4.2, Gateway H323, Cannot hear the othe side

Unanswered Question
Feb 19th, 2008

Hi

I am facing a weird problem here; I had configured 3845 Router to be work as H.323 gateway for Cisco Unified Communication Manager 4.2. The interface to the PSTN is FXO - temporarily - until E1 is received.

If I called the Analog line, I can receive the call on an extension, but I cannot hear the calling party (other side)

If I called outside, I can reach my destination but again, I cannot hear the called party (the other side) but he can hear me perfectly. I even cannot hear any progressive tone until the call is answered.

I am not behind a firewall, all the ports are open, Router and CCM are on the same

VLAN.
