I have about 15 lines in a small office. Period. Currently using phonebooth.com as a cloud service to our Polycomm VOIP phones.
My plan is to build an asterisk server with SIP trunking from Digium, port some or all of the numbers and save $200 - $300 on the phone bill.
Any suggestions about which implementation of asterisk to jump into, or versions of the software, or tips for success, or things to watch out for. . . . or HELP! We are a small office and even if our phone needs grow, it’s not going to be by a lot. I am interested in UC, but that is not the main thing at this point. Just looking for a strong solution that will just work.
