[SIPForum-discussion] Calls to Fax

[Zuñiga, Guillermo]

Hi fellows.

 

I am doing a fax call to a PSTN Number and  the calls can be completed,

1.Seeing info the flow of the call, I would like to know if you see the flow is correct to the Fax Call, based on the draft(http://tools.ietf.org/html/draft-mule-sip-t38callflows-02)

 

2.Why the call could be dropped?

 

My other question is: 

3.In all the fax calls the after the transcoding is make to change to t38, the call need to get one INVITE to change back the Media Codec, like I see in the screenshot 

At time (40.441)? Is that correct flow?

 

Thanks for your help.

Guille
