Internet Telephony talks to Popular Telephony founder Dmitry Goroshevsky who promptly trashes the whole concept of PBX. “What do I need all this infrastructure for if I just need a phone? There is no longer a need for an $80,000 PBX (or IP-PBX) or even the need to spend $1,000 for a SIP end-point phone.” He points out Skype’s security problems, and why network admins hate it. You can read that really long-ish interview or head on over to Business 2.0 and get a quick fix. So how does this work? “I cannot explain technologically how it works, because obviously it’s a secret. Basically, by you using our core as let’s say you would use a database engine. The only difference is that it’s not running on any kind of server, but it’s actually running on all the phones combined together,” Dmitry tells IT.
