CUCM 8.6 h323 gateway registration

i am registering h323 gateway with CUCM 8.6

H323 GW does not register, H323 is a peer to peer protocol.

What are you seeing that makes you believe it is unregisterting?

And how do you confirm the gateway is kind of down ?

H.323 gateway never shows registered in CUCM Admin page, like MGCP gateway does. I hope we are on same page on this point ?

thanks for the replies.

H323 gateway doesnot registers with CUCM and the status is always UNKNOWN, but once the process is done the IP ADDRESS is shown by CUCM.

in this case everything is working FINE but after some time the gateway start showing the IP ADDRESS as unknown.

however there is no configuration changes or anything.

Re: CUCM 8.6 h323 gateway registration

hmm, is this just the status issue or calls to the gateway are also affected ? Havent seen any relevant bug but just wanted to confirm it's buggy behavior.

BTW, what's the IOS version running on the gateway router ?

Re: CUCM 8.6 h323 gateway registration

i just deactiveted the Cisco CallManager service and then re activated it again.

Now the gateway is registered and IP ADDRESS is also shown in gateway page.

how i can find out if its a BUG.

Re: CUCM 8.6 h323 gateway registration

There is one bug but I cant say it for sure unless we see the CUCM traces. But here you go with bug ID : CSCtw80016

There are multiple reasons for this behavior & not just the Bug. It wd be best to engage TAC with CUCM traces.

Your IOS version is fine & I am sure the gateway config also would be okay, as you are able to register the gateway initially.
