[asterisk-users] Struggling to make sense of sending DTMF and why DIAL is trying to make multiple calls?

Hi there; I'm trying to dial into a Zoom conference, send some digits,
wait, send a name, and be "in the room", as it were.

I thought this would work:

same => n,Dial(PJSIP/02036950088 at
voipfone-205,12,r(callWaiting)D(WWW12345W#WW::))

But it didn't, so I tried all of these:

same => n,Dial(PJSIP/02036950088 at
voipfone-205,12,r(callWaiting)D(:WWW12345W#WW:))
same => n,Dial(PJSIP/02036950088 at
voipfone-205,12,r(callWaiting)D(::WWW12345W#WW))
same => n,Dial(PJSIP/02036950088 at
voipfone-205,12,r(callWaiting)D(WWW12345W#WW:WWW12345W#WW:WWW12345W#WW))

Still nothing. So I thought send_DTMF might work.

Of course, this is too simple, and doesn't work:

[dial-zoom-bcab]
exten => s,1,Verbose(1,Dialling BCAB Zoom)
    same => n,Dial(PJSIP/02036950088 at
voipfone-205,,U(dial-zoom-bcab^called_channel^1)))
    same => n,Wait(3)
    same => n,SendDTMF(1234#WWW#WW)
    same => n,Playback(technical-support)
    same => n,SendDTMF(#)
    ;same => n,Wait(15)
    same => n,Hangup()

So I found an example of how to dial, and then send DTMF at
https://wiki.asterisk.org/wiki/display/AST/Asterisk+15+Application_Dial

[dial-zoom-bcab]
exten => s,1,Verbose(1,Dialling BCAB Zoom)
    same => n,Dial(PJSIP/02036950088 at
voipfone-205,,U(dial-zoom-bcab^called_channel^1)))
    same => n,Playback(abandon-all-hope)
    same => n,Hangup()

exten => called_channel,1,Answer()
    same => n,Wait(3)
    same => n,SendDTMF(1234#WWW#WWW)
    same => n,Playback(technical-support)
    same => n,SendDTMF(#)
    ;same => n,Wait(8)
    same => n,Return()

Not only did that not work, but I rapidly got an email alerting me to
having run out of ITSP credit (fortunately I only keep £2 or so and
the calls are only 1.2p each).

What I hadn't noticed on the log was that asterisk was making multiple
simultaneous calls, and even after I had hung up!

Here's my ITSP log for the latest batch. The only way to stop the
calls was to restart Asterisk. I'm confused (and concerned) as hell as
to how this happened with that example code above?

Time, ext, number, duration.

[asterisk-users] Struggling to make sense of sending DTMF and why DIAL is trying to make multiple calls?

Revisiting this with Asterisk 16 a few months later - I spend a whole
night on this, trying to figure this out.

Would anyone mind looking at this thread on the forum where I've added
more debug info?

Many thanks
