[cisco-voip] UCM 5.1.3 Sub - IP phones will not reset

[Mike Lydick]

Has anyone experienced issues where phones will not reset and take
updates from a Subscriber at a remote location (changes made on pub).
We have run database state reports and all looks good. The pub and sub
are on separate sites less than 80ms delay. The issue began several
months after deployment. remote site phones reset and get updates if
homed to the the sub located on the same site as pub.  TFTP is pointed
to the local sub.
