I've been scouring the boards for days with no success.
I've got a Cisco 2651XM with a 7940G hanging off one side, and a 2FXO port card plugged into an analog extension of a Toshiba CIX 100 PBX (in the UK).
I've configured the router as below, but when I call the analog extension from another phone plugged into the Tosh, the Cisco phone rings, and I can hear the person on the Cisco phone, but they can't hear me. Strangely, I can press the keypad and they can hear that, but they can't hear any speech.
Calling between the Cisco 7940 and IP communicator (the only two phones connected to the 2651XM) works fine.
Can anybody tell me what I'm doing wrong?
I know it's not an ideal setup (I'd rather use BRI but we don't control the PBX, getting it changed is to difficult currently, and this is proof of concept.
