Local handling of SIP UPDATE Requests at SBC 4500 with SW 6.4.0
Hi all,
we have Session Border Controller 4500 with SW 6.4.0 ( nnSCX640m6p2 ).
On one access realm we have SIP PBX of one customer, which is then via backbone realm
connected to IMS Core and further to MGCF, for Break-Out scenarios.
This SIP PBX has a problem with SIP UPDATE Requests, coming e.g. from MGCF.
Although INVITE from SIP PBX side contains UPDATE in Allow header, it rejects UPDATE Requests.
Is there some feature / option on SBC to handle & answer such UPDATE Request locally,
to avoid that dialogue is broken due to UPDATE reject from SIP PBX ?
Thanks in advance,
