Hi Jaap,
Here is a portion of my coding. Hope I didn't 'break' anything in moving
sections around.
I tried to leave only what is material to answering your question.
One caveat - I did add the CALL FILE functionality on my V1.6.0 (branch
SVN)
asterisk box; so, maybe they changed some 'underlying' code that would be
different from V1.4.x. But, go ahead and try it. The obvious syntax change
I've noted in the comments below.
[voicepulse-in]; this is an incoming PSTN call from the VOIP provider
; VoicePulse Connect, which from their servers
; in either SIP or IAX protocol.
; .........................................................
; This section catches calls coming in through VoicePulse.
; The EXTEN here is only of interest if I subscribe to multiple
; PSTN-SIP/IAX lines from VoicePulse CONNECT.
