MGCP Endpt Unknown & heartbeat?


Im using a Cisco 3620 with a NM-HDV-2E1 and IOS 12.3.3. This is what the config looks like:

controller E1 1/1

framing NO-CRC4

ds0-group 0 timeslots 2-31 type none service mgcp

description E1 IMT


mgcp call-agent x.y.z.w 2727 service-type mgcp version 0.1

mgcp package-capability rtp-package

mgcp package-capability as-package

mgcp default-package ms-package

mgcp sdp simple

mgcp bind control source-interface FastEthernet0/0

The output from show mgcp statistics is the following:

UDP pkts rx 1362, tx 1753

Unrecognized rx pkts 0, MGCP message parsing errors 12

Duplicate MGCP ack tx 0, Invalid versions count 0

CreateConn rx 0, successful 0, failed 0

DeleteConn rx 272, successful 0, failed 272

ModifyConn rx 0, successful 0, failed 0

DeleteConn tx 0, successful 0, failed 0

NotifyRequest rx 8, successful 0, failed 8

AuditConnection rx 0, successful 0, failed 0

AuditEndpoint rx 1057, successful 0, failed 1057

RestartInProgress tx 397, successful 397, failed 0

Notify tx 0, successful 0, failed 0

ACK tx 0, NACK tx 1349

ACK rx 13, NACK rx 0

IP address based Call Agents statistics:

IP address x.y.z.w, Total msg rx 123,

successful 0, failed 123

System resource check is DISABLED. No available statistic

AuditEndpoint increases on the time.

A debug mgcp packet extract looks like this:

01:28:36: send_mgcp_msg, MGCP Packet sent to soft.switch.ip.address:2727 --->

01:28:36: 500 407 Endpt Unknown

If i look at the Softswitch output, i see the incoming MGCP message, where the GW is responding to a AUEP message saying "Endpoint unknown".

Also, i see a lot of msgs coming in from heartbeat@soft.switch.ip.address.

What am i doing wrong?

Also, the E1 IMT is down. Is this the way its supossed to be?

Thanks for the help!
