Monitoring Conversations
A conversation is a group of flows that are grouped based on the call to which they belong. A voice call typically has four flows: an RTP and an RTCP flow in the forward direction, and an RTP and an RTCP flow in the reverse direction. If the gateway controller does not create RTCP flows, the call has two flows: an RTP flow in each direction.
You can view conversations with the show services pgcp conversations gateway gateway-name command. You can view information for all conversations, or you can include keywords to limit the number of conversations displayed or to display conversations for a particular:
- Source or destination port
- Source or destination prefix
- Source or destination routing instance
- Protocol
- Service set
