FXO Port paging...no audio

[commsguy]

I am having problems getting audio across an amplicenter 100 connected to a 1760 FXO port using mgcp. The connection is made and i can hear tones but the voice path is not completed. Any ideas?

Go ahead and post your config...you need to make sure you have 'voice rtp send-recv' in global config mode. Below is cut from the command lookup tool on

http://www.cisco.com

voice rtp send-recv
To establish a two-way voice path when the Real-Time Transport Protocol (RTP) channel is opened, use the voice rtp send-recv command in global configuration mode. To reset to the default, use the no form of this command.

voice rtp send-recv
no voice rtp send-recv
Syntax Description

This command has no arguments or keywords.

Defaults

The voice path is cut-through in only the backward direction when the RTP channel is opened.

Command Modes

Global configuration



Good Luck!

This is already set.

If the FXO port is going offhook and you are not successful, the issue may lie in the termination to the paging system. Have you tested the FXO with a standard POTS line?

turned out to be a problem with the 1760 router i was using. moved it to a different chassis and it worked.

1760's have their fair share of problems...I have been going through non-support of dot1q and SRST during failover for some time now. Still no fix for the 1760. Works fine on other router platforms though. Cisco just seems a bit slow on this box.
