CSCuq21425 - CoreDump due to SIP Trunk Configuration to SME

Hello,

 

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.

Resolution: Create a separate SIP Trunk to both SME nodes and add them in a single Route List.

 

Thanks,
