VoIP Mailing List Archives

I have read the post about the touch tone before to connect so
transfered calls don't end up in voicemail boxes of mobile phones. I
have done some work last year on transfering an inbound call to
different extensions by using meetme() and local channels so a whole
group can start talking. I end up with a remarkably low number of
lines and it is actually working . It is just a proof of concept that
can be complemented with voiceprompts and a mechanism to make sure
that just one extra line enters the conference room. If you have
improvements please share them on the mailing list. I hope someone
will find this usefull.

Below are the actual Asterisk lines. It is pure old fashioned Asterisk
without any additional AGI scripts or whatever.
With friendly regards,

; this is where te inbound call is routed to with exten =>
<whatever>,n,Goto(inbound_forking,s,1)
;;;;;;;;;;
[inbound_forking]

;;;;;;;;;;;;
; this are the three local channels used for dialing the external or
local numbers. In this
; example all the numbers are external
;;;;;;;;;;;;
exten => s,1,Dial(local/intern1 at meetme&local/intern2 at meetme&local/
intern3 at meetme,20)

;;;;;;;;;;;;
; this is where the inbound call is routed to the conference room,
notice the /n

exten => s,n,Dial(local/inbound at meetme/n,10)

[meetme]
;;;;;;;;;;;;;;;;;;;;
;; extension for the inbound call
;;;;;;;;;;;;;;;;;;;

exten => inbound,1,MeetMe(9000,qM1)
exten => inbound,n,Hangup()

; extensions for the three (or more) different outbound lines
; that are routed into a macro
;;;;;;;;;;;;;;;;;;;;
exten => intern1,1,Dial(SIP/3120xxxxxxxx/0031621xxxxxx,
20,M(meetme_test))
exten => intern2,1,Dial(SIP/3120xxxxxxxx/0031642xxxxxx,
20,M(meetme_test))
exten => intern3,1,Dial(SIP/3120xxxxxxxx/0031556xxxxxx,
20,M(meetme_test))

; this is the macro for joining the conference room
; first it read the number of
[macro-meetme_test]
exten => s,1,Set(ROOMNUMBER=9000)
exten => s,n,MeetMeCount(${ROOMNUMBER}|COUNT)
exten => s,n,Wait(2)
exten => s,n,SayNumber(${COUNT}) ; as long as the number is 0 or 1
it makes sense to join

exten => s,n,Authenticate(1) ; here is the one
touch needed before you can join. A voicemail box of a mobile can't do
that <
exten => s,n,Meetme(9000)
exten => s,n,Hangup()
