Voice on the Net Conference IMTC Efforts to Support and Encourage Interoperability! Interoperability to Ubiquity Data Video Audio Matt Collier President IMTC Vice President, Polycom
The Agenda • Standards Definition • Standards Organizations • IMTC Activity Update • IMTC Voice over IP Forum
Standards or standards? • Adopted Standards vs Market standards • Are “free” applications free? • Who benefits from open standards • Do Standards stiffle competition? • Do Standards freeze innovation? Standards Key? Aren’t communications products that don’t communicate BROKEN?!?
ITU - Setting Multimedia Communications Standards • Developing interoperable open standards for multimedia communications for > 10 years • Focused on real-time conversational services • Addresses multiple levels: • Audio and video encoding • Data protocols • Network interfaces and protocols • Call setup and management • Multinetwork Interworking Whose Standards?

VoIP Forum Mission Statement • "Define and promote a simple implementation agreement in an open forum setting for voice and voiceband data traffic over an IP network that ensures seamless product interoperability and a high quality of service." VoIP Forum
VoIP Forum: ”A Watershed” • rich cross-industry representation • client SW & HW • PSTN gateways • directory services • service providers • voice response services • network / backbone • cross-organization liaisons -> re-use available and appropriate standards • address and agree on technical issues that might not yet have a standards-body home -> provide input to these organizations VoIP Forum
VoIPAccomplishments April 1, 1998. The IMTC announced that its members have approved the Voice over IP (VoIP) Interoperability Implementation Agreement (IA 1.0). The goal of this specification, which was developed by the IMTC VoIP Forum, is to support two party voice and voiceband communications.
