asterisk users - Jun 2006 - IAX DID channels as incoming hunt group?

Hi:

I am looking into getting incoming IAX DID channels for our office. I've
found a provider.

What I want, though, is an incoming hunt group -- that is, say we have
three lines:

555 1212
555 1213
555 1214

Calls coming in on 555 1212 may end up on any one of the three. If 555
1212 is busy, the call forwards to 555 1213, and so on.

I was under the impression that this has to be done by the carrier or
provider, but I want to make sure: if they are IAX channels, is there
any way to do this in Asterisk on the receiving end?

Shouldn't a provider offering IAX DID be able to do this for me before
the calls are sent to my Asterisk server?

Cheers,

-Stephen-

In the VoIP world technologically there's no reason why you would need 
an incoming hunt group as you say. As a call comes in, the provider 
would forward it to you - there's no actual group of channels... just 
your account information. Now - some providers may limit how many you 
can actually have up simultaneously but that's a feature of their system.

You just do pattern matching in your dialplan:

[from-myIAXprovider]

exten => 55512XX,1,Dial(SIP/reception,40,T)
exten => 55512XX,2,Voicemail()

So anything coming in with a dialled extension of 55512XX will pattern-match
to the above lines.

This is completely unnecessary. A provider giving you IAX DID service can send
you as many channels as they (and you) want, for a single incoming number.

That only works if the caller has dialled one of the other numbers.

If we only publish one number (555 1212), what then?

no from the Asterisk perspective it will work regardless of the number
dialled as long as it matches the 55512XX pattern. As  others have pointed
out though, it's just easier to have a single DID and your provider allow
multiple channels or instances of the same number to hit your box. 

it's hard sometimes to let go of concepts from the legacy PBX world when you
try to integrate their equivalent in Asterisk. For example, I still enforce
the "dial 9 to get an outside line" in my setups even though there is
no
technical reason for doing do. The reason is because people can't deal with
dialling direct and it becomes a training issue. The other one that always
makes me laugh is people depressing the hookswitch to flip between calls
even though they have line indicator buttons right there, flashing on their
phone. Fortunately Snom phones allow this functionality.
