I will be moving soon to VoIP.
In my desk I have some offers from diferent vendors. (Siemens, Shoretel ...)
But the offer with the most atractive price include a Draytek VigorIPPBX 3510
Is this a good product ? How it compares with other similar VoIP PBX ?
My office has around 50 extensions.
And finally a last question for the VoIP gurus., some vendors ofers me a "Hybrid" sollution, using a mix of former telephone lines (RDSI) and Internet to make calls, other offers me a full "Internet Only" sollution, my calls are 50% to local country and 50% International (we are based in Spain)
I'm a litle bit reluctant about a "Full Internet only" sollution, is it safe ?
