Hi!
I have a three-part problem/question. I am trying to make a subscription to
an eventlist using
the SUBSCRIBE method. Subscribing works well, but when I try to unsubscribe,
problems
occur.
1)
Namely, for some reason sofia SIP on server side replies 200 OK to the
*unsubcribing*
SUBSCRIBE message (Expires set as 0). For my knowledge this should be 202
Accepted.
Am I right? I am wondering why sofia sip behaves like this?
2)
According to the logs, 200 OK reply to the unsubcribe comes to the client
*before* the NOTIFY
request. The logs show that after receiving the 200 OK response, the
subscription is removed;
and when the NOTIFY comes the process goes into a default leg. Then the
client responses
with 420 Bad Extension. Do you think this is due to the received 200 OK
(instead 202)? In
my opinion, the subscription should not be terminated until the notify
comes... This is interesting
because I am using a darcs version where this problem is corrected. I had a
brief discussion with
Pekka last spring about the issue.. So do you think this behavior may be
because of the 200 OK?
3)
This is the case when Sofia sip is automatically sending responses. How can
I switch the auto reply
off for subscriptions?
