Fixed a bug related to a ClassNotFoundException when viewing the contents of MMTelCONFView profiles. (VOLTE-2125) N.B. Upgrading to 2.3.1.10 via export/import will error on the MMTelCONFViewTable. While this error is trivial, to avoid it you can delete MMTelCONFViewTable.xml from the export prior to importing.

Fixed a bug related to re-writing the Event header of NOTIFY requests when Sentinel acts as a B2BUA. The bug would manifest by the Conference Focus generating a NOTIFY in response to a REFER, but the NOTIFY would not propagate correctly through upstream B2BUA instances. (VOLTE-2104, STLSIP-1122)
