show rtp-stat traceroute

Last Updated : Nov 06, 2012 |

Displays the automatic session traceroute result. You can filter the results according to subnet address or rtp-statistics session index. If the RTP statistics application is enabled (see rtp-stat-service), the Branch Gateway VoIP engine issues a UDP traceroute for every active RTP session. The traceroute is performed 10 seconds after the session begins. A traceroute is not performed if there is another active session to the same destination for which a traceroute was already performed within the last 5 seconds.
