[Spce-user] 2 asterisk subscribers - subscriber sst setting ignored?

[Matthew Ogden]

Hi all,



I have two asterisk subscribers, and SPCE sitting in the middle. My domain
is setup to ignore SST by default and rely on SEMS to dead call detection.
The caller asterisk configuration itself has SST set to refuse. The called
party doesn’t have this set to Accept.



Then the caller calls the callee, its passing the “supported: replaces,
timer” in the INVITE to the callee. The callee asterisk box, picks this up,
an in its 200 OK, says “require: timer”. All goes well for 15 minutes, and
then the calls ends, because the callee, does a REINVITE, the REINVITE goes
through to the caller, and the caller says “420 Option Disabled”.



1)      If SST is disabled, why is it passing “supported: replaces, timer”
to the callee?

2)      Why is the callee reinvite being passed to the caller? (Surely the
reinvite is only for its leg of the call?)



I can disable it on my callee, but I was wondering if 1 or 2 above is
actually a bug in SPCE as well that should be looked at?



If its SPCE or Homer teammembers I can give you the pcap, and any logs you
need if you want.



Regards

matthew
