Hi,
I have a 2801 router and want to configure it for using QSIG. I am using MGCP. I tried a lots configurations in order to get the endpoints (VWIC2-1MFT-T1/E1) registered. But, I still see them unregistered on the call Manager (device --> Gateway).
But, if I make a "show ccm-manager hosts" I get the following message:
MU-GW-2801#sh ccm-manager host
MGCP Domain Name: MU-GW-2801
Priority Status Host
============================================================
Primary Registered 172.17.7.5
First Backup None
Second Backup None
It says registered. I do not know what am I missing. When I synchronize the gateway with the CUCM, the ".cnf.xml" is downloaded to the gateway and lots of lines are added to the running-config. But, it still says unregistered endpoints in the CUCM.
Any idea on what am I missing?
Thanks in advance,
BAGAZ

Could it be because I haven't got the PRI terminated and it should be up to complete the registration? It appears as registrated under "Show ccm-manager"...
THANK YOU

Hello,
Here are a few things to try.
no mgcp
no mgcp bind control
no mgcp bind media
Serial x/x:23
no isdn bind-l3 ccm
isdn bind-l3 ccm
exit
mgcp bind control source [int]
mgcp bind media source [int]
mgcp

Hi BAGAZ,
You hit the nail on the head my friend. The "Endpoints" will not
register until the PRI has been connected and Layer 1 connectivity
is established
Cheers!

Thank you very much for your help!
So I will wait until I have the primary to connect it and see if the endpoints register in CUCM.

Hello Rob,
I think CUCM and Router are only about layer 3 relative. The CUCM backhaul the layer 3 info from router. The router will transfer the info of L1 and L2 back to the CUCM for it to make a decision. Even the router doesn't have L1 connectivity, it can still register with CUCM.
I did a lab today. I found the CUCM can register with my E1 PRI even the router 's isdn's layer 1 status is deactivated. So I think that means the layer 1 connectivity is not established. Does that mean my lab and your words has conflicts? Or I just misunderstand what you were trying to say?
Thank you.

I have same issue with BAGAZ. In my lab, I don't have any E1 cables. So, the controller is down. In the CUCM shows unregistered. The gateway is ok.
BAGAZ have any updates after your E1 was activated.
Thanks,

Hi Thuc,
You can try physically shot the E1 pairs [1,2 - 4,5, 1 with 4 and 2 with 5] and controller would come UP.
MGCP would show registered in CUCM.
