Hi, all. I've got an old Telrad PBX with an Emagen(?) voicemail box. The VM box, itself, is beginning to show its age. Big-time. We're thinking it might be time to look for a replacement. I'd love to install Asterisk with an FXO card or something, but I don't think it supports whatever protocol legacy PBX's used to speak to VM systems. If someone can tell me I'm wrong, a six pack of their favorite $BEVERAGE will magically appear at their door. Thanks much! -Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

First, unplug one of the ports that goes to your voicemail and plug a regular pots phone into it (PBX). Make a call to VM (has to go out on the port you have the handset plugged into), answer it and listen. If you hear a bunch of DTMF then you are golden. -- Thanks, Steve Totaro +18887771888 (Toll Free) +12409381212 (Cell) +12024369784 (Skype) -------------- next part -------------- An HTML attachment was scrubbed...

Usually old VM interfaces are nothing more than analog extensions, anyway, so your original plan is probably solid. j> > > > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > > > _______________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users >
As others have said, this is certainly possible. Our old NEC phone system had us in the same boat. It "triggered" voicemail by ringing the VM extension(s) and sending a DTMF burst of the extension to record VM for within 1.5 seconds. In our case, when any call came it in went to the voicemail system to play the main menu and allow the person to dial an extension. With that we were able to move a small set of "power users" to SIP phones for testing before we decided on a final phone and moved the whole campus.

Wow. Thanks for all the replies! Something just occurred to me, though: which side would be FXO, and which side would be FXS? The PBX? Or the Asterisk/VM side? Thanks again for all the info! -Ken On Wed, July 1, 2009 3:36 pm, Jared Smith wrote:> On Wed, 2009-07-01 at 13:05 -0400, Ken D'Ambrosio wrote: > >> Sounds like good stuff, but my most substantial concerns involved >> things like MWI: is asterisk able to "push" that back to the PBX? > > Does your existing PBX use SMDI to interface with your current voicemail > system?

There may be some arcane Telrad secrets that will make your life much easier. For example when interfacing with Nortel PBX's you can create DISA trunks which give you internal 'intercom' at which point you can invoke Nortel features & commands including raising the message waiting indicator. Nortel also made (& perhaps Telrad did too) a special ATA intended for interfacing specifically with external voicemail systems. Nortel called it the VMI adapter (NT8B89DA). The nice thing about the VMI was that it handled all of the secret proprietary Nortel signaling voodoo, freeing you from the need to kludge-up a bunch of DISA trunks & routines :-). Just to add 2? to what others have said, I think what you're talking doing is a great idea. In my opinion, forklift upgrades concentrate disruption into a narrow window for everyone all at once which can have greater impact than a series of smaller 'fires' that necessarily accompany any migration. That is to say nothing of the non-trivial burden of migrating physically from cat3 2-wire infrastructure to Category 5 MANAGED 802.11af Ethernet. -Karl
