[asterisk-users] Inserting a wait in a sip dial

[David Gibbons]

<snip>
'w' is really only supported on channels where digit-by-digit dialing is
the  norm, which generally means analog trunks (or digital trunks using
CAS signaling).

Thanks Kevin, that's what I figured (though not quite so concisely)...

Going foward, is there any way to programmatically inject DTMF tones into an already-bridged channel?

So:

1. dial 12345
2. connect SIP provider to * extension
3. wait 2 seconds programmatically
3. inject 567 DTMF tones into channel to signal remote PBX of extension to dial

I'm hoping there's another way to skin this cat.
