Dialogic HMP parameter IPPARM_DEFER_PENDING_REINVITE possible side-effects HMP 3.0 Win, SU 367

Hi,

We've had problems with SIP RE-INVITEs and SIP 491 in our environment with HMP 3.0 Win SU 367 and we followed this page to solve them:

http://www.dialogic.com/support/helpweb/helpweb.aspx/4280/powermedia_hmp_rejects_a_re_invite_with_491_request_pending/PM_HMP_WIN

But now we are seeing that some INVITEs sent to Dialogic HMP are taking too long to have a response, the PBX tries to resend the unanswered INVITEs 4 times until the PBX quits trying.

The parameter IPPARM_DEFER_PENDING_REINVITE can be the source of those problems?

I'm attaching a packet capture of the scenario, IP 192.168.46.43 is the Dialogic HMP host, IP 172.17.0.200 is the PBX host.

Thanks.
