[Asterisk-Users] Re: Astersk as AVAYA IVR

I've got 2x PRI 30 lines coming in to the Index, and I have 4 spare PRI
cards in the Index.  I was thinking about using a QUAD PRI card from Digium
and having the calls come into the Index then transfer to Asterisk for IVR
then back to the Index.   That way if we get 60 inbound calls we'd in
essence be using all 6 PRI cards in the Index.  (2 for termination to PSTN,
2 for outbound calls from Index to Asterisk and 2 for calls back from
Asterisk to Index).

tromboning or anti-tromboning so I suppose each call will have to take the

so you have ACD on the AVAYA?  are you thinking of front ending all calls to
the ACD with the IVR?  I would think that you would set the IVR up as an
option within the ACD instead of front ending all calls to the ACD.  The
flexibility of * is great for this and I have built several IVR's for
customers using * as the telephony engine.  does require knowledge of some
scripting language to run the AGI scripts in (PHP, PERL etc.)

Your assumptions on routing are correct.  a path out of the Index to the *
will require a path back to the Index.  not sure what you mean by
'tromboning' but it may be in reference to using the same b-channel on the
pri to route the call back to the Index.  not sure about that, would require
some analysis of d-channel messaging.  most systems that support PRI
networking have some special d-channel signalling and it may just be a
question of building something in * that the AVAYA needs to see to
accomplish this.

Good Luck
