Has anyone got this to work in an 8.6 environment? It seems to work sometimes and then it stops. The only way I can get it to start working again is by rebooting the router. The client is running 8.6 with the 2900 series routers (latest IOS 15.2.T1). I've got the Enable Caller-ID checked in the FXO ports, caller-id enabled on the voice ports and the MGCP res package installed.
CUCM - 8.6.1a
2901 - 15.2.T1

We are running in to the same issue, runnning MGCP on FXO ports caller -id says Unknown Number , CUCM ver(7.1.3 )
1) Some of them said they were able to resolve the issue using the commands.
timing guard-out 1000
ormgcp persistent offhook
Can you tell me in what version of CUCM ??
2) Also, when you say enabled "caller -id " on gateway page from CUCM. Where exactly is that option. I am having difficulty finding it. Is it only available in CUCM 8.X and later ? or am I missing it ?
3) Was any one able to resolve this on CUCM 7.X ?
CUCM 7 does not support caller ID running MGCP. The only time it began support caller ID over MGCP is 8.6 which it didnt work for me to well. Inconsistent. For the issue that I ran into, I just moved them to H.323 and left it. I use H.323 for all my gateways from now on unless I am running into a SIP trunk. I would move it H.323 and you wont have a problem. You have to setup SRST anyway, right? Once you build your H.323/dial peer config, your SRST config is 95% done. Just my 2 cents.
I understand all your frustration here but be aware that while H.323/SIP for FXO CLID Name works in small deployments it doesn't scale well as your system grows. Just think about how you would have to manage this configuration if you had over 100 FXO gateways running H.323? In that case MGCP perhaps becomes a nicer choice as you can centralize the dial-plan and management on CUCM and the routers have a cookie cutter config.
New features like MGCP supporting CLID Name on FXO ports are great but as we all know they take time to become stable and 'just work'. I would caution you not to make long lasting architectual decisions based on a new feature's initial burn-in period.
