[Asterisk-Users] Asterisk Flash Transfer (callthrough)

[Chris Wilson]

Hello Everyone:)!,

I have a Incoming/Outgoing SIP Trunk setup to Broadvoice, is there a way to
send a "Flash" over the trunk, for example, to do flash transfers and
call-waiting?

I tried to use Flash() but it seems to not work on the sip trunk, my
configuration is as follows:

exten => 500,1,Goto(callthrough,s,1)

[callthrough]
exten => s,1,SetVar(NR=)
exten => s,2,Background(privacy-prompt)
exten => s,3,ResponseTimeout(10)
exten => s,4,WaitExten(20)

exten => _X,1,SetVar(NR=${NR})
exten => _X,2,Goto(s,3)

exten => *,1,Goto(s,1)

exten => #,1,Playback(transfer)
exten => #,2,Flash()
exten => #,3,SendDTMF(${NR})
exten => #,4,Flash()
exten => #,5,Hangup()


Debug output is as follows:


Please let me know, thanks! :)
