Configuring Cisco Intercompany Media Engine Proxy

SIP Trunk URI: 81a985c9-f3a1-55a0-3b19-9654@UCM-30;maddr=192.168.10.30

Codec-name: G722

Payload type: 9

Note If calls are not going through the Cisco Intercompany Media Engine, you can also use the show tls-proxy session command to troubleshoot the success of the TLS handshake between the components in the Cisco Intercompany Media Engine system. See the command reference for information about this command.

show uc-ime signaling-sessions statistics

Displays statistical information about corresponding signaling sessions stored by Cisco Intercompany Media Engine Proxy. Failure of signaling sessions in the Cisco Intercompany Media Engine can occur for different call-related reasons; such as failure of ticket verification or domain name verification, or offering RTP over the Internet.

Ticket domain check failed: 2

Route domain name check failed: 1

RTP over UC-IME: 2

Note Call-related failures, for example, can be due to the service policy rule being reconfigured or the primary ASA operating in failover mode. If a service policy rule for the Cisco Intercompany Media Engine Proxy is removed (by using the no service policy command) and reconfigured, the first call trasversing the ASA will fail. To resolve this issue, you must additionally enter the clear connection command and restart the ASA. If the failure is due to failover, the connections from the primary ASA are not synchronized to the standby ASA.

show uc-ime media-sessions detail

Displays the details about all active media sessions (calls) stored for the Cisco Intercompany Media Engine Proxy. Use this command to display output from successful calls. Additionally, use this command to troubleshoot problems with IP phone audio, such as one-way audio. If no calls are currently up, this output will be blank.
