The Avaya Voice Portal is an XML based IVR application server.. its
connection method is SIP only and can be interconnected to almost
any standards based SIP system or directly to SIP trunks from a SIP
provider. How you would connect it in your environment would really
depend upon your exact requirements.. if connecting to an Avaya PBX
there may or may not be any hardware requirement depending upon
model and configuration.. and I am seeing the IVR placed in front
of the PBX more often than I did in the past.
As far as CTI connectivity.. web services is the preferred method..
but again your environment would dictate the exact topography..
It all depends on what you are looking for in your environment.
With the older IVR version (AIR) you can connect with Either E1's
or VOIP(h.323). With the new version Voice Portal, you can connect
with either SIP trunks or h.323. For IP connectivity, you need to
connect it to a C-Lan card on the CM. For E1 you need to connect it
to a DS1 card via the NMS card on the AIR box.
Avaya offers different options when it comes to hardware, because
you can buy a software only option and provide your own hardware or
you can buy the whole solution.
As for CTI, you will need a CTI server, on Avaya side it is the
AES. AES will provide you with basic CTI functionality but if you
want a full blown CTI solution you will need to look at something
As for integration with other vendors it is very possible. I have
done AVP integration with numerous Avaya ACD's and Cisco CM's.
