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.

What does the Flash key do in SIP?

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.

…

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.
