MGCP
The MGCP field indicates the configuration status of the Media Gateway Control Protocol on
the CMG. If Down - the MGCP protocol on the CMG is disabled, and no softswitch control of
the CMG is possible through MGCP. If Up - the MGCP protocol on the CMG is active, and
ready to communicate with an external call agent.
RSIP Status
This is a combination field that indicates RSIP keepalive status and support for Session Border
Controllers (SBC). The format of the field is:
RSIP: Gateway RSIP State RSIP mode Status: RSIP Status
The field values are as follows:
Field Value
Gateway
RSIP State No Reply The call agent has not answered.
Resolved The RSIP was answered OK.
RSIP mode Wildcard The RSIP message mode is one wildcard message for the
entire gateway.
Each
Endpoint The CMG Router card will provide an RSIP message for
each voice channel. (For an SBC, for example.)
RSIP Status Wait The CMG Router card is in the Random delay period before
sending the first RSIP.
Sent The CMG Router card delivered the RSIP and has not
received the OK yet.
Up The CMG Router card received the OK.
KA-TO Keep-Alive Timeout. Indicates that there was a timeout
when the CMG Router card was in a keepalive mode. For
SBC endpoint keepalive support, the SBC must send MGCP
messages to each endpoint to restart the CMG’s MGCP
Keepalive endpoint timeouts. Typically, this is an AUEP or
AUCX message, but any MGCP message to an endpoint
works. If no MGCP message is received before the
Keepalive timeout, the CMG restarts that channel and RSIPs
toward the call agent for that endpoint.
