CUCM 8.6(2) migration problem with external calls

dimensyssrl · ‎08-03-2012

Hello all.

Yesterday we have migrated our telephone infrastructure from CM4.x to CUCM8.6(2), after some weeks of tests.

Yesterday night all seems to work properly, all phone updated and registered, external calls going out and in.

But from this morning, with all users at work, it appears a strange problem, that until now I couldn't solve: randomly all external calls go down.

I can't address this problem, since gateways (all cisco 2811 routers) are the same and with same configuration as yesterday.

All thing that I can think is that router that seems to cause the problem is configured not with mgcp by cucm, but with h323 route inside the router.

Any suggestions will be greatly appreciated.

What does the debugs on the GW say about the disconnect cause and who's issuing it?

GW says normal call clearing.

But, maybe I've addressed the problem.

I've found a bug fixed into latest cucm release (8.6(2a)SU1) that say "h.323 calls improperly disconnected".

So I'm trying to upgrade from 8.6(2a) to 8.6(2a)SU1, but process fails :-(

I've tried from a dvd and also loading iso image from sftp, but after few minutes appears an error

Anyone can help me?

I've read about a bug that can disconnect h323 calls, and this bug is solved in 8.6(2a)SU1 version, but I can't install this version into our 8.6(2a) cucm...

Problem is always the same, also after a reboot:
