CSCuq21425 - CoreDump due to SIP Trunk Configuration to SME
Ran into this issue today in our CUCM environment where our CUCM Publisher had a CoreDump. My CUCM backtrace is below. This turns out to be in reference to Bug ID CSCuq21425 and caused because the SIP Trunk on the Leaf CUCM Cluster only has 1 SIP trunk to the SME, with both of the SME IP addresses.
