Hi, We are looking at deploying Asterisk for about 60 phones. Since we are in a public building, and are a mixed university and federal unit, we must have our phones up near 100% of the time. Currently we have ~60 POTs lines. I am working on moving us to DIDs with a single PRI feeding us. The reason this came up, is that we are planning on growing to over 150 users within the next 2-3 years. My idea is to have a well planned/tested Asterisk server, with a spare on hand (identical, including the digium quad T1 card). We are looking at HP 2650-PWR switches (one of each floor, each with ~30 VoIP phones). For UPS power we are looking at an APC 2200XL-NET with a large extra battery (the big APC one), for each switch, and one set for the server. Our data switch infrastructure would also be on the 2200XL-NET, but we are using HP 2848 Gigabit switches, and the power draw is much less than the 2650-PWR. Two areas that I am running into trouble with is either some FXS/VoIP gateways or a channel bank, for 9 analog devices (6 on the first floor, 3 on the third floor), 7 of which are fax machines. We can probably put a channel bank in on the third floor, and run the analog devices on both floors). Phones. We are looking at either a mix of the Uniden 200 and the Zip 4x4, or all Zip, or all Uniden. I have looked at others but the Snom 205 is not much cheaper than the Zip 4x4. We need 802.3af PoE support. Multi "line" would also be quite useful. Does anyone know if the problem of not hearing dialed digits during a call still exist with the Uniden. I can probably get enough budget to do all Zip 4x4 phones, but I want to know real world experiences with the two, before I push it one way or the other. Before we make a full decision, I am going to bring one of each in house. Any other suggestions or recommendations would be handy. Both myself, and our systems programmer (him more than me) have worked with Asterisk before, but not for such a deployment.
