I do believe that they still do, but I have never liked the 'surviable" epn because of problems with them. I like the idea of a seperate pbx that is dcs ed to the other pbx, but that is only my opinion.
Not sure what you are asking. I have a WSP and it works fine And if my ppn goes down the epn kicks on great. If you clarify your question, maybe I can help answer you.
I have a new building going up that will require about 40 phones plus voice mail. In the next city (same agency) I have a G3si V11 duplicated in 2 single carrier cabinets with Intuity LXi and an E-CAS. I want to install an EPN off the existing G3si in the new building so that I have the 4 digit dialing, access to paging, E-CAS and a common voice-mail. I know fiber between the locations will fire up an EPN, but does AVAYA make an EPN that can survive on it's own (with CO lines?) in the event the fiber link goes down. I guess I'm looking for the best of both worlds!
Sorry to bend your ear..
No I do not believe you can use local co lines. My WSP works well with fiber, but we have ATM's between the sites.
What I have done in the past for your type of situation is run T1s between the sites to my main site and run VOIP.
We have a hanger that supports about 30 people, plus all a conference room and phones thru out the hanger. We ran 2 T1s to the site that is about 40 miles from the main building. Put some voice cards in a router and it works fine. They are on the same dialplan, just like they were in this building as everyone at corp office. Never have had a complaint. In fact if I didnt need to service the routers, I would never know they were there. Its like being in the same building.
It saved us lots of money to do it this way as well.
If you want more info let me know, I can forward some info to you.
