I'm looking for a way to give VoIP capabilities to an existing PBX: it's made by Mitel and it's used in a small/medium environment (a few dozen phones, but the PBX has capabilities for up to 200, if i remember correctly). Any high-level guidelines on how to integrate Asterisk with a PBX that's already in use? Probably that particular PBX is not supported directly, but are there ways to somehow hook-up to it and route calls from IP to PBX or back? Entirely replacing the existing PBX with Asterisk is probably out of question, for reasons that dip a bit into the non-technical realm. :-) Thanks in advance, -- Florin Andrei http://florin.myip.org/

I recommend the Adit600 personally but YMMV. I recommend the channel bank over using the TDM400P with FXS ports as I have found through my use of the TDM400P at home (3 ports) that the channel banks are by and large more stable and have better voice quality, although it's a fine line. I'm doing the T100P+Adit600 route on a few Norstart MICS systems right now, and will be converting one of htem to a PRI interface and ditching the channel bank to save on wiring and also to experiment with some DID/CLID experiments with the Norstar system.

Using a real world example, lets assume you want to add 12 extensions and 12 "phone lines" that process through the asterisk box. I use those numbers because they add up to 24 which is the number of channels a single T1 is capable of signaling. Your hardline PBX would then wire into a channel bank and then using a TDM T1 card into the Asterisk box. Planning a good extensions.conf would allow the two to work seamlessly together. Extending our real world example, a user on the Hardline PBX calls an extension that you've designated needs to goto the asterisk box, it travels down into the channel bank, into the T1 signaling, into asterisk, and out whatever means you need it to travel(SIP/IAX/H323)). (Hardline User)->Channel Bank->T1->Asterisk->(H323, SIP, IAX, ...) For specific help doing such a task you probably need to sit down and think out how you want it laid out. If you're a DIY guy, then ask specific questions with examples to the user list, or for consulting type support ask around in the biz list. -----Original Message----- From: asterisk-users-admin@lists.digium.com [mailto:asterisk-users-admin@lists.digium.com] On Behalf Of Florin Andrei Sent: Monday, June 21, 2004 2:19 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] integrating with existing PBX I'm looking for a way to give VoIP capabilities to an existing PBX: it's made by Mitel and it's used in a small/medium environment (a few dozen phones, but the PBX has capabilities for up to 200, if i remember correctly).

Here is a good place to look. You either need analog FXO or FXS ports. http://www.voip-info.org/wiki-Asterisk+legacy+integration I also have a little info on my site. http://www.totarotechnologies.com/Articles/General_VoIP_(Voice_over_IP)/Are_you_looking_for_an_affordable_way_to_add_VoIP_capabilities_to_your_existing_PBX_phone_system?/28/ Thanks, Steve Totaro Totaro Technologies, Inc. 410.985.7114 ----- Original Message ----- From: "Florin Andrei" <florin@andrei.myip.org> To: <asterisk-users@lists.digium.com> Sent: Monday, June 21, 2004 3:19 PM Subject: [Asterisk-Users] integrating with existing PBX> I'm looking for a way to give VoIP capabilities to an existing PBX: it's > made by Mitel and it's used in a small/medium environment (a few dozen > phones, but the PBX has capabilities for up to 200, if i remember > correctly). > > Any high-level guidelines on how to integrate Asterisk with a PBX that's > already in use?

Hello, I'm trying to setup asterisk with T100P and Adit600 (3FXS & 1FXO), can you please help with the configuration needed?
