[SIPForum-discussion] specific case with a=inactive

[Traussnig Robert]

Hi!
 
I'm not quite sure if this is correct but because of the fact that you
didn't get a SDP in the Re-Invite you have to give an offer in your
200ok. So you have to decide if you send a=inactive again or a=sendrecv.
Maybe someone have a better answer.
 
Best Regards,
Robert

Betreff: [SIPForum-discussion] specific case with a=inactive



Hello everybody,

I have a quick question related to the SDP signaling behavior in a
specific hold case. My scenario is the following:

 

Incoming Re-invite of an established voice call with the following
content of SDP:

            c=IN IP4 0.0.0.0

            ...

            a=inactive

 

In the 200ok I confirm the attribute line:

            a=inactive

 

and the call is hold - everything ok. 

Later on comes another Re-invite without SDP for the same call. Now my
question, if I answer in the 200ok for that Re-invite with SDP do I have
to repeat also the: 

            a=inactive

attribute or do I send now my SDP again with 

            a=sendrecv

 

Thanks and Best regards

Joerg
