voice class h323 1 wasn't good enough to avoid Recovery on timer expiry

Hello, my pub and sub were down due to maintenance outage to the location, however I had another sub that took place. So, all the phones were successful registered to this sub. However during the outage we were not able to make inbound calls to any sites because the ISDN Recovery on timer expiry.Thus, I've applied these commands:

voice class h323 1

h225 timeout tcp establish 3

voice-class h323 1 - for all voip dial-peer

--------

Now the funiest thing is: 13 of 14 sites worked fine after I applied these commands, one site I also had to change the preference in order to fix the timer expiry, however there was only one site that did not work at all. I was wondering to know if someone out there would be able to explain why these commands did not work in this specific site. Btw, the router is 2951 IOS 15.0(1r)M13 H.323 to CUCM 8.6.2, isdn switch-type primary-qsig in Germany.

Here is the debug I took when I faced this issue for that specific location:

voice class h323 1 wasn't good enough to avoid Recovery on timer

Service Provider is disconnecting the call after about 30 seconds:

        Cause i = 0x82E6 - Recovery on timer expiry

This is expected, 30 seconds is too long for a call signaling

I'm pretty sure CUCM was not replying to the H323 Setup promptly.

Next time, grab the h225 messages as well to see if they're going out.

debug h225 asn1

I do not believe there is nothing related to the CM because 13 of 14 sites worked just fine, and all those sites are associated to the same CM.

Brian, thanks for the tip I hope I will not face this again, but I'll keep in mind for this command.
