Description (partial)

Call gets disconnected and the CVP log shows an exception like "DsSipDialogException: Cannot send UPDATE" encountered.


During a blind Xfer, the CVP SIP component may disconnect the call when UCM trunk sends consecutive UPDATE messages within a few msecs of each other.

The problem has not been found before because customer was using a blind transfer to a DN that goes to a route pattern and out h323 gw, where the first 3 digits are stripped off.  It is not a route point to a ICM script as usual blind xfer works with IPCC.  This causes 3 unexpected updates to ANI to be sent to the caller on the SIP Trunk.
