[asterisk-users] How do I create an IVR/Dial Group that works properly?

[Alan Lord (News)]

Hi all,

I am trying to understand how I can get a simple IVR scenario to work 
properly (having already removed most of my hair...).

The basic requirement is as follows:

* Caller arrives at our main number
* Caller is greeted and then told they can enter an extension number, if 
known, or wait and their call will be connected to an available rep.
* The IVR then dials a group of extensions (if the caller didn't enter 
one obviously).
* Someone picks up the call and the connection is established and logged.

Now, I have all of this working apart from the last piece.

My IVR rings various extensions and I can pick up the call just fine. 
But my problem is that the data asterisk records regarding the call is 
wrong.

It correctly identifies the CallerID, but it always records the 
destination as "s". Not the extension of, for example my SIP phone (101).

If the incoming caller dials 101 whilst in the IVR, the log is correct.

I can see *why* I am having this problem (There is no extension when you 
arrive in the IVR other than "s"), but I cannot see *how* to fix it.

Please can I ask how do others handle this so it works properly (I've 
included the basics of my DP below)?

I'm running Asterisk 1.4.21.2~dfsg-1ubuntu3 on Ubuntu Server 8.10.

Thanks

Alan


Here is the IVR which callers are dropped into:

[tolc_menu] ; Welcome and information to callers
exten => s,1,Answer()
exten => s,n,Wait(2)
exten => s,n,Background(welcome-to-tolc) ; Say Hello
exten => s,n,Wait(1)
exten => s,n(tryagain),Background(enter-ext-of-person&or) ; Enter
extension number if known, or
exten => s,n,Background(pls-stay-on-line) ; Trying to connect...
exten => s,n,WaitExten(5)
exten => s,n,Macro(belllord,${ALANL}&${ALANB},303)

exten => _10[1-5],1,Macro(call_extension,SIP/${EXTEN})

exten => _20[1-5],1,Macro(call_extension,IAX2/alanb/${EXTEN})


The Vars ALANL and ALANB are:
ALANL=SIP/101
ALANB=IAX2/alanb/202


Here is the Macro belllord:

[macro-belllord]
exten => s,1,Dial(${ARG1},20,t)
exten => s,n,Goto(s-${DIALSTATUS},1)

exten => s-NOANSWER,1,Voicemail(${ARG2}@business,u) ; business is the
voicemail context, ${ARG2} is the mailbox number to dial
exten => s-NOANSWER,n,Hangup()

exten => s-BUSY,1,Voicemail(${ARG2}@business,b)
exten => s-BUSY,n,Hangup()

exten => _s-.,1,Goto(s-NOANSWER,1)


Here is the call-extension Macro:

[macro-call_extension]
exten => s,1,Dial(${ARG1},20,t) ; Ring channel for up to 20s
exten => s,n,Goto(s-${DIALSTATUS},1) ; Go to either no answer or busy.

exten => s-NOANSWER,1,Voicemail(${MACRO_EXTEN}@garden_house,u)

exten => s-BUSY,1,Voicemail(${MACRO_EXTEN}@garden_house,b)

exten => _s-.,1,Goto(s-NOANSWER,1)
