Hi all,
Actually I have two question here.
First one is the one explained in mail subject. In detail, we know, sofia
stack automatically responds with 200OK for incoming CANCEL.
My purpose is just to add an special customized SIP header into this 200OK.
By checking related code, I didn't find any clue to achieve this.
So without modifying stack code, is there any simple way, like including a
TAG somewhere to meet my requirement?
Second one is more specific to sofia fundamental framework, which is I
expect to prevent some event/signal from being reported to application.
The mechanism is just like, we unmask certain OS signal using
'pthread_signal_mask'. With this methodology, sofia stack only sends event
which application
layer is interested upwards to save both a bit cpu usage of upper
application and sofia stack.
Thanks
kandy
