I don’t really understand this piece too much, but The Polycoms (and many other phones) use TFTP to pull their application binary, configuration settings, and other information. TFTP = Trivial File Transfer Protocol.In my setup I purchased a NetGear FS728TP-100NAS Some ‘pre-built’ / commercial PBXs have POE built in. Many modern phones can be powered through the ethernet cable that they use to communicate with the LAN, this eliminates the need for power adaptors for each individual phone. This is box that sits between your telephone endpoints (SIP trunk or POTS) and your phones connected to your lan Essentially your phone lines are routed through your internet (similar to Skype).
I did not utilize a SIP Trunk in my setup, but from what I understand you basically grab a special card that then connects through your WAN to a remote SIP Trunk provider. SIP Trunk = A digital alternative to POTS.This is the traffic that will travel over your LAN and communicate with your office phones (in my case, Polycom 321s and Telephone.app) POTS = Plain Old Telephone Service = Analog Lines = Copper Lines.Hopefully this compilation of notes will help someone in a similar situation develop and deploy a VOIP Asterisk based solution. Although VOIP may seem a bit intimidating with all the lingo and plethora of options, it isn’t as hard or mysterious as it may seem at first. It took me about a week of full-time work to figure out how all the peices fit together and deploy the system.
#POLYCOM CONFIGURATION FILE GENERATOR TOOL TRIAL#
After some research and a lot of trial and error I was able to get the entire phone system deployed for less than $2,100 ($350 POE switch, 10 phones * $85, ~$900 analog card, used an old Windows box lying around). This seemed a bit high considering the simplicity of the needs of the company. Proposals from a couple providers yielded total costs of a 10 hard phone + 10 soft phone system to be around $8,000 – $12,000 with an ongoing contract. A basic PBX to support the phone needs of a small company was all that was needed. The company was not looking for a unified messaging system, video conferencing, color LCD phones with automatic VPN connections, etc.
