Can dialogs be used safely?

Hi all,

 

I have been working on a B2BUA service that in many aspects relies on
the Dialog implementation offered by the nist-sip stack. During
development the service have been softly tested through the different 

use cases and the results were successfull. But after a series of tests
under moderate load conditions, errors and unexpected behavior became
visible. Without being able to point out a concrete failure in the

service, and given the exceptions coming from the nist-sip stack and the
SIP RA (the service is executed on top of Mobicents application server),
we start questioning how much is it a good idea to keep relying

on the dialog objects provided by nist-sip instead of using other
solutions (whenever adequate for a BUBUA kind of service). Are the
dialogs safe to use or is it a deprecated choice for a reliable User
Agent.

 

Thanks.
