Don't know why but I seem to be having a lot of problems with getting CUCM 8.6 to successfully register with my 2851 GW router. It's my understanding that it should be relatively straightforward and easy. Here were my steps,
1) Add GW in CUCM, it's my understanding that the domain name is the hostname of the router then . and the domain name.
Domain Name* PSTN_ROUTER.cciev.com
2) Here is my config in the 2851 GW Router,
ip domain name cciev.com
ccm-manager config server 192.168.2.202 (This is my Subscriber IP)
mgcp call-agent 192.168.2.202 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
no mgcp timer receive-rtcp
mgcp fax t38 ecm
no mgcp explicit hookstate.
Below is a screenshot of the debug mgcp error I get and a show of ccm-manager. It seems to stick at REGISTERING TO CM and the TFTP DOWNLOAD FAILED counter seems to keep climbing. I can't seem to get past this part.
Everything I read seems to point to domain name and set up in CUCM but I have tried every combination available and even tried without setting a domain name on the router but still experience the same thing. I even upgraded IOS to 15.1(4)M4
If someone can point me in the right direction or pass along some step by steps I would appreciate it. Thanks in advance for your time!
can you attach the show tech.
is this a brand new setup?
try pinging the cucm from the gateway, check and let me know the result?
what are the end-point that you are trying to resgister?
have you tried registering the router with just the domain name PSTN_ROUTER rather than
When you register a MGCP gateway, you register a end-point in this case what are you trying to register T1/E1,FXS,FXO?
Is the callmanager service ON?
As said try doing a extended ping to the CUCM from the gateway, check if the CUCM is pingable?
debug mgcp packets (this would help)
Try this (make sure this is done during a downtime)
reset the gateway once.
no mgcp no ccm-manager config server 192.168.2.202no ccm-manager config ccm-manager config server 192.168.2.202
ccm-manager config mgcp
Thanks for your reply. This is indeed a new setup, it's my home LAB. I have tried multiple naming conventions with and without the domain name involved. Network connectivity does not appear to be a problem. Trying to register up two 2MFT-T1-D1 cards, one of the cards is in a NM-HDV.
I see where I can insert an image or a video but I don't see where I can insert a text file with the show tech?
Go to use advanced editor option on the to right corner when you reply and when you scroll down you can attach the
show isdn status
follow the steps:
1> Make sure that your T1 interface is up i.e: MULTIPLE_FRAME_ESTABLISHED:
2> Do the following:
no mgcp no ccm-manager config server 192.168.2.202
no ccm-manager config ccm-manager config server 192.168.2.202
ccm-manager config mgcp
3> RESET the mgcp gateway on the cucm page.
4>Check the call manager services in servicibilty TRY to restart the services:
