Also look at an Adtran Atlas 550. You have your one Network PRI/T1 from the telco to one port and then you put in a quad T1 user interface module. Then you can route your DIDs to whichever server they are destined to inside the Adtran's CLI Menu driven interface. It is very simple to work with. if you go to Adtran's website you can find detailed instructions on how to setup an oversubscribed PRI with an Atlas 550.

<div>I have a few questions for the brain trust that is the biz list... Any thoughts, critisims or flaming is welcome. </div>
<div> </div>
<div>I am looking to use 1 T1 (PRI) to split between 3 systems. Let me give you an idea of what we are talking about:</div>
<div>1. Asterisk PBX that runs our internal business phone system, (4 Lines) using a TE12OP digium card with the T1 and VoIP for the internal communication.</div>
<div>2. Asterisk Voicemail system using VoIP for inbound and outbound to a gateway that is attached to the T1, (4 Lines) (Possibly the Asterisk system in 1???) RIght now there is no card only ethernet. (Althoug I do have a 4 line digium analog card if that makes it easier.)
</div>
<div>3. A Hylafax system running as a Efax platform for commerical purposes. (4 to 8 lines) Using a Digium Te220 card attached to the same T1.</div>
<div> </div>
<div>Now for the questions. Does this even sound feasible? Can I split the T1 between the 3 devices? </div>
<div>Can the Asterisk system in 1 be a POTS to VoIP gateway for the second asterisk system? I would be willing to use the analog card if that last scenerio isnt possible, but what do I use to break the analog lines off the T1? I already have the 2nd system developed and running in a production environment, the other 2 are in development.
</div>

<div>Any ideas are welcome.<br>Nate</div></blockquote></div>

<div>All 3 are good ideas. I already have all the hardware I mentioned so saving money on cards at this point isn't really the focus. Also for the same reasons combining the 3 servers into one seems a little risky, I would hate to bring down my 2 core products because I made a change to my internal PBX system. (The thought of my customers trying to call into my office because their voicemail and fax systems are not working and reaching a fast busy is quite scary! But it is great to know that it works!) I do like the idea of using a quad card to chain the systems to other T1 cards. My guess is that is going to produce the lowest latency and the cleanest calls. I beleive we are going the SIP route internally for the PBX system but because of issues with Fax and VoIP the voicemail and fax system have to be straight T1. As for TDMoE I am not aware of what this is. Time for a little googling to look into that. Thanks for all of your ideas. I am glad to see that I am not completely off base.
