Attended Transfer with one-way audio
Hi All, I'm facing a strange behaviour in FS after a Attended Transfer. For the A leg listen the C leg, C needs to press some DTMF key. Otherwise only C leg can listen A leg. My scenario is: A (external) ---> TDM/SIP Gateway ---> FS ---> B (extension) ---> Attended Transfer ---> C (extension). Both extensions are SIP Phones registered in FS. If the transfer is Blind, the audio works fine. Other test: If the A leg is also a local extension, the audio on Attended Transfer works fine too. An important point is that all transfers are made pressing "Flash" key in SIP Phone not by att_xfer in Dialplan. So, any clue to start? Thank you, Alex. <http://pt.slideshare.net/marketingteclan> <http://blog.teclan.com.br/>

Hi Bote, Extension B sends a REFER event to FS that responds with a 202 Accepted and after a NOTIFY. I guess it is the same as using dialplan with att_xfer.

att_xfer in dialplan isn't the same as a sip refer. /b On Tue, Mar 29, 2016 at 1:45 PM, Alex Pierry <alex@teclan.com.br> wrote:

Ok Brian, as you can see I'm not a SIP specialized. But I did the same test using att_xfer and the behaviour was exactly the same. But nevermind, I posted this topic to see if someone has passed by this situation. By the replies I think nobody. It should be some stupid thing I'm doing. Let me come back to the logs.
