Good evening ladies and gentlemen. This will be my first phone system I have installed. I've been in IT for a long time now, and have occasionally had to kick the odd PBX on a Saturday morning, but I have never had to program one from scratch before. Anyway, enough about me. I've been asked to think about a new phone system for one of my clients. I have been looking at 3cx for a few months now and have had a limited play using my laptop and android devices. I was a little worried about the latency I was experiencing with that set up, but put that down to no QOS and everything being on the same domestic wifi. Anyway I took the plunge and installed 3cx on my customers DC, and ordered 2 Cisco SPA504 phones to set up a test rig, and it worked great. I chose the Ciscos over Polycom's because I had a nasty experience with a polycom phone, and i like Cisco Kit. The sound is great and they feel like they can take a knock or two. The other makes I hadn't really heard of so i'd rather keep to something I half know. So lets get to it.... We are looking at probably 17-18 handsets, I don't think I need anything more than a SPA504 with sidecar for the office receptionist. I don't know how 3CX likes being in a Virtual Machine, We are sailing a little close to the wind all ready with our Virtual Servers so I think i'll just grab a HP Micro Server to run 3CX from. Now what are the actually MINIMUM specs for 3cx? I cant see it being that much of a hog. I'm thinking of using two Patton SmartNode 4114's to interface with the 8 lines coming into the building. I'm choosing these firstly because 3CX list these as the preferred, plus the fact there seems to be less complaints about these in the forums. Now, whats the consensus about VLANing your phones, do you bother, or do you just let your switch's do what they do best? My next question is WIFI SIP phones.. They use a couple of DECT phones for roaming around, with a hideous mosh up of repeaters. I've just put in a new WIFI infrastructure giving epic coverage, so I'm thinking of not going DECT and going WIFI. This way their current grey and black spots will be eliminated. But what is a good phone to get? All the makes I think are good seem to have axed their product lines. I like the look of the Cisco WIP310 but that seems to have been discontinued. I need something that isn't a cheap, over featured, lightweight imported phone. Currently it seems the Polycom SpectraLink 8002 may be my number one choice, does anybody currently use WIFI phones? My next question is the last (for now)... As I said before, we have 8 lines coming in. Now this customer is a school, and their phones are provided by the council. It is a very basic service, we have 8 phone jacks, with 8 normal phones pluged in. Now these lines are actually part of a council wide system, ie, we have to dial 9 to reach a outside line, but if we want to call anybody within the council's umbrella we just dial the 5 digit number. Now we don't have a PBX here, it is all managed centrally by the council, so we would be retrofitting 3CX onto the back of it. So that is making me think about the dial 9 for an outside line.. Now instead of having to dial 9 to get an outside line from 3CX, then dial 9 again to get outside of the council, what are my options. The council numbers all start with the same numbers, either 34 of 35 and are 5 digits long. Now can I use outbound rules to add the second 9 for me to any phone numbers that are longer than 5 digits? Thanks for your time. I hope this is enough Detail Thanks again for staying awake through this Daniel ____________________ EDIT Sorry, I forgot to say that we would be stepping up to a purchased product should this all work out compatible.
