Hello All,
I am subscribing to message-summary events and then, at a later time,
unsubscribing.
Here is the unsubscribe scenario:
1) My UA invokes nua_unsubscribe().
2) Sofia-sip correctly transmits the SUBSCRIBE message with Expires=0
3) The SIP server replies to this with a 401 Unauthorized Message
4) Sofia-sip re-sends the SUBSCRIBE message with authorization, but
WITHOUT the Expires field (SHOULD STILL BE Expires=0)
5) Sofia-sip reports Event Callback: 100 Request Authorized by Cache
6) The SIP server replies with 489 Event Header Missing
Is this a bug? Or am I doing something wrong?
Best Regards,
Jerry
