Commander system to VOIP?At work we have 3 phone lines coming in, a fax line (which the adsl is connected to), and 2 voice lines. If one voice line is busy, the call is diverted to the other. You probably can tell that Im not an expert in how commander/pabx/whatever systems work. I want to change our voice lines to voip to save money. We have a Linksys WAG200G as our modem, which AFAIK, does QOS. What else do I need as far as hardware goes, to get this all working. Its important that I can use hold and transfer features working too. Music on hold is important, and Id really like to be able to get some kind of "out of hours" message going, but its not a priority at the moment.
The main benefit of having small office phone systems with PBX features is that it is possible to maintain multiple extensions with a single telephone connection. The service supplier keeps all the equipments at their site and puts forward PBX services through a hosted server at fixed monthly fee.
