I was pleasantly surprised by the announcement that SKYPE has finally opened up to SIP based PBXs. You can register for the beta program here. This is amazing news for the VoIP industry and I believe will further accelerate its growth. SKYPE has good international rates, and calls to Skype users are of course free. More importantly, customers using SKYPE can call your company at nocharge! For many businesses this will mean more customers. Something to be welcomed in time of recession!
