[cisco-voip] 7911s not working after upgrade

[Jason Aarons (US)]

SCCP Version number with firewall? Is firewall doing SCCP fixup?
Google sccp version number, Ryan or Wes have posted about fixup before.

Subject: [cisco-voip] 7911s not working after upgrade

 We upgraded from 6.1.3b to 7.1.5.11900-6 over the weekend. We have
several sites in India where the 7911 telephones are not working now. They have dial tone
but when they call out they get a "UCM down" message. When we call them on cluster the
phone rings and when they answer we get a "temp fail" message. At the same sites we have 7940 and 7941 that are working. These phones are all behind a firewall. 7911 phones in the United States that are not behind a firewall are working fine.

Opened a TAC case and I am downgrading the firmware on one of the 7911s to see if that makes a difference. Wondering if anyone has any thoughts?

Thanks,
Steve
