[asterisk-users] Switching between Music on Hold streams. [13.8.2]

[Jonathan H]

Hi there;

I didn't see any "G" option in the example above, and the usage for
the option parameters is entirely undocumented at
https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Application_Dial

The G options are as below
G - If the call is answered, transfer the calling party to the
specified priority and the called party to the specified priority plus
one.
context
exten
priority

I think I have something almost there now, with the following:

[streamdemo]
exten => s,1,Answer
exten => s,2,BackGround(menu)
exten => s,3,WaitExten
exten => s,4,Goto(s,2)
exten => _[2,3,4,5],1,Dial(Local/${EXTEN}@play-radio,,G(play-radio^${EXTEN}^2))
exten => _[2,3,4,5],2,Goto(s,2)

[play-radio]
Exten => _[2,3,4,5],1,Answer
exten => _[2,3,4,5],2,MusicOnHold(${CALLERID(name)}${EXTEN})
exten => _[2,3,4,5],3,Set(CHANNEL(language)=en_GB)
exten => _[2,3,4,5],4,BackGround(menu)
exten => _[2,3,4,5],5,WaitExten
exten => _[X,t,i],1,Goto(streamdemo,s,2)

However, it's like the play-radio channel can't "hear" the dtmf.

Here's the output -  once that MoH starts playing, no amount of button
pushing works. All I'm left with is a channel which isn't closed
properly when the phone is hung up.

By the way, it looks like that "G" option IS working because the MoH
starts, then the "called party" plays back an example piece of "menu"
audio while the MoH is playing, but seems to ignore the keypresses.
