I have a multi cluster deployment with SME providing intercluster communication via SIP. Please refer to the diagram below. I have LBM configured on all my UCM servers. I have configured the link to CUCM-A with only 5kbps to force the call to fail (OutOfBandwidth). Calls from Phone B1 fail as expected. Calls from Phone B2 trigger the OutOfBandwidth flag, but are allowed to route to their destination. Both phones B1 and B2 are configured with the same device pool, location, etc. The only difference between the two is one is a hard phone, the other is IP Communicator. Can anyone help?
Phone A1 <====> CUCM-A <=======> SME <=======> CUCM-B <========> Phone B1
\\ =========> Phone B2
