Notice in this packet that Cisco IOS is also sending the H.245 address and port number to

Cisco CallManager. Sometimes the Cisco IOS Gateway will send the unreachable address, which could cause either no audio or one-way audio.

The following debug output shows that the H.245 session is coming up. You can see the capability indication for codec negotiation, as well as how many bytes will be present in each voice packet.

*Mar 12 04:03:57.217: cc_api_caps_ind (dstVdbPtr=0x616C9F54, dstCallId=0x11, srcCallId=0x12, caps={codec=0xEBFB, fax_rate=0x7F, vad=0x3, modem=0x617C5720 codec_bytes=0, signal_type=3}) *Mar 12 04:03:57.217: sess_appl: ev(23=CC_EV_CONF_CREATE_DONE), cid(17), disp(0)
