FreePBX as stand-alone voicemail for Avaya Definity

FreePBX as stand-alone voicemail for Avaya Definity

FreePBX as stand-alone voicemail for Avaya Definity

(OP)
Asterisk 13.22.0
FreePBX 14.0.13.26
Avaya Definity v9.5si, IP enabled (but not SIP capable)

I am an old Avaya guy, and a newbie to Asterisk and Perl scripting. And I apologize profusely for the length of this post.

I am trying to set up FreePBX as a standalone voicemail server for an Avaya Definity PBX, v9.5si.

I have an ISDN PRI between the Definity and the FreePBX server. I am successfully sending calls over the PRI to the FreePBX server and am successfully leaving messages in mailboxes.

The issue is getting Message Waiting Indication from FreePBX to the Avaya. FreePBX is calling the Avaya, but is not sending any digits.

I have the PRI set up in two groups - channels 1 through 22, and channel 23 in it's own group (on both ends). Channel 24 for signalling. I use only channel 23 for MWI (dahdi/g1/).

I am using the following Perl script for MWI. I added the line numbers to this for clarity (they are not in the actual script).

On line 23 I set $DEBUG to "1", but the file "/tmp/asterisk.log" is not created.

The block from line 026 through 033 seems to work, as I see the caller ID name and number in the trace on the Avaya side. Asterisk shows the call completed successfully.

On line 104 I set the MWI On code to "106".
On line 141 I set the MWI Off code to "107".

I am expecting FreePBX to send 7 digits - MWI ON code + 4-digit extension.For Testing, on the Avaya side, I am checking for the number of incoming digits, then route the call to a vector that routes the calls to the string of digits received. Unfortunately, I am getting zero digits.

The only time I receive digits are when I manually add them to the end of line 026, such as

CODE

my $callFile = "Channel: dahdi/g1/1062234 
Then I get 7 digits. But that's not the way.

Any experts out there have any suggestions?

Thanks in advance -

RE: FreePBX as stand-alone voicemail for Avaya Definity

Great idea. Have thought the same, with the cost of voicemail systems going crazy, this is awesome.

Is there a way to insert a pause in your digit string? Like 106,,,2234. If you manually dial the mwi codes from an analog phone, is it code [tone] extension?

Have you giving console permission, COS, to the asterisk ports? Have you tweeked the MWI option in system hospitality I think?

RE: FreePBX as stand-alone voicemail for Avaya Definity

Additional question, instead of setting up as a trunk, would it work better to setup as 24 separate stations?

Should still get the callerid from phone system. I am not sure Definity will take MWI feature code from a trunk. Years ago I setup a call center off of a Definity with Asterisk in between. Agents used cheap sip phones to sell condos down in Carribean.

RE: FreePBX as stand-alone voicemail for Avaya Definity

With Avaya Audix, it used a CLan interface and analog ports. Would it be best to put a network hub in between a working interface like this, use something like wireshark to capture the interactions and then use a CLan interface instead of T1/PRI?

RE: FreePBX as stand-alone voicemail for Avaya Definity

(OP)
I don't know if Asterisk will allow a pause to be programmed. Everything in my original post was found in a variety of different places on the web.

If I dial 1062235 from another phone on the system, I turn on the MWI on the phone for 2235. I don't currently have any analog stations on the system to test from - only digital sets. then dialing 1072235 turns off the MWI. So I know that the codes work.

I'll test console permissions on the MWI port today.

I did try to set up the single PRI channel as an analog (DS1FD), but didn't get anything. I'll play with it some more today. I'm also looking at an SMDI device that would connect to the asterisk server COM1 port and a Definity digital set port. The FreePBX software has SMDI options included.

RE: FreePBX as stand-alone voicemail for Avaya Definity

So dialing 1062235 from a Freepbx phone turns a light on? or from Avaya phone?

RE: FreePBX as stand-alone voicemail for Avaya Definity

I would set up a single channel off of the T1 to look like a 24 single stations on the Definity side. Connect to FreePbx as 24 separate trunks so that you can, if need be select which of the 24 trunks, you send the calls out.

Connect a sip phone to Freepbx, send 1062235 out over a select trunk/station on the Definity side. On the Definity side list trace the station to see if the digits are coming across.

Additionally, change station COS to give console permissions and change system features to give that station system wide message permissions.

RE: FreePBX as stand-alone voicemail for Avaya Definity

An additional thought, are message waiting lights even necessary? Are you thinking too traditionally? Now days, people want the voicemail emailed to them as an attachment. They no longer want to play the voicemail from their phone anyway.

If you are getting the call from Avaya and putting it in the correct voicemail box on the FreePbx side, then just configure to send the voicemail as an attachment and delete.

RE: FreePBX as stand-alone voicemail for Avaya Definity

(OP)
There are no phones on the FreePBX/Asterisk box. It is strictly being used for voicemail.

It's an older Avaya system in a school environment. During class hours, calls to teachers are sent directly to voicemail. Need the indicator lights to alert teachers to new messages. Don't have infrastructure in place to support sending emails.

Will play with analog stations instead of trunks.

RE: FreePBX as stand-alone voicemail for Avaya Definity

Understand about no phones connected to Asterisk. I would set one up for testing, dialing the message on / off digits. Could even set up softphone on your pc. My gut tells me Definity requires a station to turn the lights on with the code, not a trunk.
