Asterisk GW to Avaya IP Office Server edition 11.xx 1

[R3LzX]

if anyone has done this in a production environment and can share their experience. vmpro licenses are ridiculous expensive so we are entertaining asterisk as a GW Devise for auto attendant and routing to the ip office. all phones will be J series sip and connected to the ip office only.

not so certain the asterisk will handle voicemail, I am thinking we stay avaya for that

thank you in advance

Maybe Im losing my mind... but isnt the VMPro license included with the Server Edition license?

The truth is just an excuse for lack of imagination.

you are correct, but we are talking about 100 plus sip channels for this deployment to an auto attendant, that means that we need some very expensive quantities of voicemail pro licenses, that is what I am trying to avoid

The number of sip channels does not really matter, what matters is projected inbound and internal call volume directed to the attendant.
I've never thought about using a 2nd PBX for this, but you'll be using 2 sip channels for the call anyways, cutting your capacity, theoretically, in half.

Unless of course you use the asterisk at the front. Terminate the sip trunks to that, use it to manage the calls, then transfer the calls via sip to the IPO. You can keep the vmpro for internal use and messages.
Outbound calls would go out through the asterisk.
SIP trunks between asterisk and ipo is easy peasy.

Oh so you are talking about VMPro channels gotcha. Ya I have never attempted anything like this. I would think it is theoretically possible but like AACon pointed out you will be using a lot of SIP trunk channels if it goes IPO>Asterisk>IPO. There are also limitations on number of SIP trunks (as well as number of VMPro ports) with an IP 500 V2.

The truth is just an excuse for lack of imagination.

I guess the amount of time you have to spend to maintain this will be more expensive than the VM Channels.

IP Office remote service
IP Office certificate check
CLI based call blocking
SCN fallback over PSTN
