Hello All,
I am trying to register MGCP with Call Manager, though the configuration is straight forward and did many a times in the past as well, may be i am missing something or something else.
I have UCM 6.1.2 & 3825 as Router,
This is what i have configured on the GW.
<Host-Name>#show run | inc mgcp
ccm-manager fallback-mgcp
ccm-manager mgcp
mgcp
mgcp call-agent <CM-IP> service-type mgcp version 1.0
mgcp dtmf-relay voip codec all mode out-of-band
mgcp profile default
As the setup is new, the router came with domainname as yourdomain.com, however i have already removed this command.
this is what i see in show ccm-manager
ATVG-DC-1#show ccm-manager
MGCP Domain Name: <HostName>
Priority Status Host

On the call manager there i have given similar hostname of the GW in the <Domain Name field>
Is there something i need to do more to make mgcp registered with ccm?
Frnds please help!!
Thanks, ~Daljeet

you might be missing something in there, maybe the backhaul to CCM, doublecheck all the config

Hello Java,
Thanks for replying to the post,
We arent using PRI, we are using FXO lines to PSTN, and which are yet to configure.
So you think i should configure FXO ports in CCM as well? to make mgcp registered to cucm?
Many Thanks, Daljeet

Hi all,
I removed all the config from the GW and ccm, and tried to add again, i just issued two commands this time
###
ccm-manager config server 10.1.102.10
ccm-manager config
###
IP being my UCUM ip, and both my routers got the remaning config downloaded from the CM TFTP.
which is
ccm-manager redundant-host 10.1.102.11
ccm-manager mgcp
ccm-manager music-on-hold
ccm-manager config server 10.1.102.10
ccm-manager config
!
mgcp
mgcp call-agent 10.1.102.10 service-type mgcp version 0.1
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 rtp payload-type g726r16 static
!
mgcp profile default
!
and i am also attaching the cucm gw page as well. for you to verify if there is any host name conflict.
Still i am unable to see any change.
I am also pasting show ccm-manager output.
ATVG-DC-1#show ccm-manager
MGCP Domain Name: ATVG-DC-1

Here is the other problem... if your router can not resolve the host name of your CUCM, then MGCP will not work. That is why I always go back to IP addresses for the CUCM server names (not actual hostnames, but you can change them to IP) When you do this, and restart the CUCM service, all MGCP registrations will be done through IP address. when your router calls into CUCM for MGCP information, it will respond back with IP MGCP information, not hostname MGCP information.
Make sure you have ccm-manager config in your router
do a no mgcp, then mgcp. This will force MGCP registration.
cheers,

Thanks man, so you mean to say i should change ip address in the CUCM server instead of ATVG-DC-1 i should put ip address and do i need to change the hostname to ip addres of VG as well or will it work with the current hostname?
I would request if you can answer me for this as well, my life will be easy if it works by tomorrow :)
Thanks a ton!! Cheers

You tell with MGCP what your Router/CUCM is using. If you put in the IP address of the CUCM in the Router, then save it, and the next time you do a Sho run, you see the CUCM has changed the Hostname instead of IP, the CUCM are using hostnames in the server names.
First question is, is this the first MGCP router on your network and CUCM? If it is, you are probably using hostnames in the CUCM server names (System, CUCM)
You have two choices:
change to IP addresses in the CUCM server names
OR
Make sure your MGCP router can resolve the hostname of the CUCM.

Yes this is the green feild implementation and there are couple of cucm's and routers which needs to be configured.
Yes we were using hostnames in cucm under system cucm, but i changed those to IP's while i was troubleshooting this mgcp issue.
if i put ip host command in the GW's for resolving cucm's hostname's with ip's ..will it work ?

Hello,
Problem got resolved after i configure all the endpoints in the CUCM and did no mgcp and mgcp.
Thanks guys for looking into it.
Cheers!!
