Re: unable to register mgcp gateway on cucm 7.x

EDDY MULDER · ‎10-24-2013

I am trying to to an very easy job which i cant understand why it is not working

On the router i have :

ccm-manager mgcp

no ccm-manager fax protocol cisco

ccm-manager music-on-hold

ccm-manager config server 192.168.120.XXX

ccm-manager config

!

mgcp

mgcp call-agent 192.168.120.XXX 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 timer receive-rtcp

mgcp sdp simple

mgcp validate domain-name

mgcp fax t38 inhibit

no mgcp explicit hookstate

!

mgcp profile default

when checking on the cli the following shown

vgw01#sh ccm-manager
MGCP Domain Name: vgw01.demuldriaan.org
Priority        Status                   Host
============================================================

on cucm:

please give me an hint what i should change to get the gateway on the cucm.

when debugging mgcp packet it reports code 500

vgw01#debug mgcp packet
Media Gateway Control Protocol packets debugging for all endpoints is on

This normally means that the naming is incorrect but i cant see the name mismatch.

Would be easier to figure out the issue using a debug ccm-manager events. Please share the debug here.

Hi

1- Please check the cable which connected from your gateway to the LAN , maybe there is flapping.

2-On the your gateway , please add the below commands:-

mgcp bind media source-interface (name of interface )

mgcp bind control source-interface (name of interface )

no mgcp

mgcp

3-Try to register your gateway without domain name

A-no ip domain name

B-On CUCM , try to register without FQDN , just name of router.

C-No mgcp , mgcp

Thank you

Please rate all useful information

Amine Nouasri · ‎10-24-2013

Looks like to me the GW is trying to register and times out. You sure about IP connectivity or firewall, access-lists maybe blocking MGCP packets?

Robert Thomas · ‎10-24-2013

Keep in mind you need two ports open for this to be succesfull.

UDP 2427

TCP 2428

If one of this ports is blocked, the port will not register.

Aman Soi · ‎10-24-2013

Hi Eddy,

can u try entering command ip host PUBLISHER HOSTNAME IPadress of PUB in router and check?

like ip host CUCMPUB 10.1.1.1

If possible, please share the complete show run of router?

regds,

aman

amansin74 · ‎10-24-2013

1. You should have your controllers up and configured on Router. Without this, it will not register.

2. You should have MGCP bind commands

Example:

mgcp bind control source loopback 0

mgcp bind media source loopback 0

3. Give the command again:

no mgcp

mgcp call-agent 192.168.120.XXX 2427 service-type mgcp version 0.1

mgcp

4. Please try above commands suggested by amanso

5. On CUCM most important is to configure Controllers correctly.

Check: show inventory

and verify you have added the right controllers. It is the Controller ports that gets registered to CUCM not the whole router.

Aman Soi · ‎10-24-2013

Hi Aman,

Initially I was also thinking of Controllers being UP but the show inventory posted by Eddy does not have any E1 cards.

regds,

aman

amansin74 · ‎10-24-2013

Hi Aman & Eddy,

Without any FXO , FXS or T1/E1 port, Router will not register as MGCP gateway in CUCM.

There is no way to use MGCP without t1e1 or analog ports.

MGCP protocol controls the controller ports not the router.

You can make a H323 Gateway or SIP Trunk VoIP dial-peers.

Would like to know what is the requirement of a voice gateway here.

EDDY MULDER · ‎10-24-2013

I AM bouncing my head against a solid brick wall as THE solution is so simpel,and mentioned in an other Thread.

"Configure THE fxs port on THE gateway config on THE call-manager".

For sure i Will not forgot this anymore....

NeXT step is to get vic2-2fxo interface so i can connect a normal pstn line to it.

Regards

Eddy

Robert Thomas · ‎10-25-2013

Hey Eddy,

It's a very common issue that the GW will show unregistered to CUCM if the T1/E1 card is connected but not up. As mentioned before you need to have some type of active voice card for the GW to be registered,
