Description (partial)

When SIP inspection is enabled with ZBF, SIP connections that use the PUBLISH message will be dropped with the following log:

*Sep  3 14:10:16.599: %AIC-4-SIP_PROTOCOL_VIOLATION: SIP protocol violation (Content length invalid / Non-SIP MSG recvd) -  dropping udp session on zone-pair INSIDE-OUTSIDE-zp class SIP-cm

This is because the PUBLISH message from RFC 3903 is not supported by ZBF's SIP inspection.

This is an enhancement request to add support for this SIP message type.
