VoIP in the organisation - wither the PBX
Conclusion: Voice over IP is having, and will continue to have, a significant impact on the telephony and PBX market. Telephony is becoming increasingly software based and is taking advantage of software-related economics. The popularity of services such as Skype1 and Babble2, and Session Initiation Protocol (SIP)3, 4 VoIP applications demonstrates this. Microsoft’s recent release5 of its SIP based Office Communications Server (OCS 2007) will have a major impact on the telephony expectations and applications on organisations, irrespective of their size.
