sip-interface option: suppress-reinvite

SIP re-INVITE suppression is automatically enabled for a SIP interface when session timers are enabled. This behavior prevents re-INVITEs whose purpose is only for session refreshes from being forwarded to the other call leg. The first re-INVITE received from a UAS on the terminating call leg will be passed to the UAC on the originating call leg since the Oracle Communications Session Border Controller has no prior INVITE request coming from the UAS to match against.

Re-INVITEs are suppressed only when the Oracle Communications Session Border Controller receives the same INVITE request back-to-back without any intervening re-INVITE request in the opposite direction, or an UPDATE or PRACK request in either direction.

Note:

The SIP reINVITE Supression parameters are not replicated on the standby system in an HA environment. The first re-INVITE after a switchover will be forwarded to the far end.
