[SIPForum-discussion] 200 OK with SDP from after PRACK message which is resulting in call failure.

[Jorge]

The call trace you sent looks like the call is being terminated from the
call originating end(the CANCEL) within one second of the call offer.  The
question that needs and answered is,  why is the call being terminated by
the CANCEL message.

 

It may be because the originating end does not support RSeq  or some other
header offered in the 183 response.

 

Compare call between the  two SIP entities and determine the differences
between the calls that complete and those that do not.

 

 

Good luck,

 

Jorge Alcantara

Hi , 

In ICE rfc 5245, it is mentioned that connectivity checks will start for the
first media stream(as mentioned in SDP) . 

There is also a mention that each media stream will have independent timers
which decides the interval between connectivity checks and RTO for those
candidates,

 

I have a doubt here.

 

Connectivity checks will begin at the same time for all media stream 

                                              OR

connectivity checks will begin for the second media stream only after first
media stream's connectivity checks are over.
