Hello,
I continue to implements MWI (rfc 3842) and I test with 3 servers
(Asterisk, Cirpack and OpenSer).
In 3 cases, it doesn't work for 3 different reasons.
1/ Asterisk:
When I send Subscribe request, I receive "200 OK" with "Expires: 0" I
think it's weird.
Logically, Asterisk should send Notify request, but it doesn't do it. So
5 seconds (UAC_WAIT_NOTIFY in evsub) after the subscription is destroyed.
If I don't reply to a call, Asterisk sends Notify request, but like
there is no subscription enabled, pjsip doesn't find module to manage this.
Do you know if asterisk manages rfc 3842 ?
Is it possible to disable the timer with UAC_WAIT_NOTIFY in pjsip ?
2/ Cirpack
When I send Subscribe request, I receive "489 Bad event" message with
"Allow-Events: dialog"
Do you know if cirpack implements rfc 3842 ?
3/ OpenSer
When I send Subscribe request, I receive "200 OK", and subscription
seems OK (perhaps no Expires = 0).
But I don't receive Notify request.
Sometimes I receive later Notify request, but pjsip displays this message :
Message Request msg NOTIFY/cseq=1 (rdata0x875c64) from X.X.X.X:5060 was
dropped/unhandled by any modules
I don't understand why because the subscription is always up.
My implementation is based on presence.c and pjsua_pres.c, and I use
1.0.x branch
Thanks for your help.
Samuel
