Well, it's moving time for our organization and I'm trying to figure out pros and cons of digital PBX (which is what we currently have) and VoIP for the new phone systems. Two questions: Anyone know a decent digital PBX company in California, with excellent customer service especially, for a 15-20 line installation? Also, anyone here using VoIP at work? I'm particularly interested in 10-20 line VoIP installations - how's the quality? Does it deliver or do you long for an analog line? Thanks!
