Need help with one-way conversation on outbound calls to the PSTN using FXO.
I have UCM 184.108.40.20600-12
Router/Gateway is 2811 with a VIC2-2FXO card and PVDM2-8
Router and UCM are connected via a point to point T1
Router is setup as H323 and voip bind is configured on interface
Internal point to point - router to UCM calls are fine, placing external PSTN calls from location/router to UCM are fine, external calls from UCM to router are fine, external calls to the FXO port - POTS line (plar to extension) are fine
Calls made from the router to UCM and back out on the router FXO POTS line receive one-way conversation. You can hear the called party, but they cannot hear you.
I am at a lost. I've checked all configuration and I am not seeing anything.
Does anybody have any ideas?
