MGCP with FXO/FXS not creating Dial Peer

Answered Question
Jan 8th, 2008

I have an issue with MGCP. I have a centralized sub and a pub, and multiple remote sites.

When adding MGCP gateways using FXO or FXS ports, the ports will not register. If I manually put in the dial-peer voip (999020 example), the register. Also, when making changes on the gateway ports, I have to do a no MGCP for the change to take effect.

This is happening on all new sites as I create the gateways. Please advise.

Sample config:

ccm-manager fallback-mgcp

ccm-manager redundant-host 10.216.11.50 10.216.1.50

ccm-manager mgcp

no ccm-manager fax protocol cisco

ccm-manager music-on-hold

ccm-manager config

!

mgcp

mgcp call-agent 10.216.11.50 2427 service-type mgcp version 0.1

mgcp dtmf-relay voip codec all mode out-of-band

mgcp rtp unreachable timeout 1000 action notify

mgcp modem passthrough voip mode nse

mgcp package-capability rtp-package

mgcp package-capability sst-package

mgcp package-capability pre-package

no mgcp package-capability res-package

no mgcp package-capability fxr-package

no mgcp timer receive-rtcp

mgcp sdp simple

mgcp fax t38 inhibit

mgcp rtp payload-type g726r16 static

!

mgcp profile default

I have this problem too.

you need one extra command -

ccm-manager config server

where IP address 1 would normally be the Pub, and ip address 2 would be the Sub.

These allow the gateway to request the actual voice port and dial peer configs to be downloaded as an XML file from the server to the router when the MGCP initially registers.

P,

Thanks much for the info. I knew I was omitting some command but could not pin point it.
