Broadcore uses the Session Initiation Protocol (SIP) open standard to deliver its hosted communications services through highly reliable converged broadband access designs to optimize real-time communications such as voice and video for guaranteed availability and quality.
Broadcore’s IP telephony solution uses Voice over Internet Protocol to establish telephone calls. This method digitizes voice and transmits in digital packets rather than using traditional circuit-committed protocols of the public switched telephone network (PSTN). Every VoIP telephone has a unique IP Address. Thus Hosted Unified Communications translates the public phone network to an IP address. When a phone number is dialed, the Hosted Unified Communications switch looks up the IP address and delivers the call to the VoIP telephone.
One of the most significant differences with VoIP, as compared to PSTN, is that backbone-trunking resources are not assigned in a dedicated, predictable manner to support a voice call. Instead, trunk bandwidth for a VoIP telephone conversation is assigned on a dynamic, as needed basis, via packet switching.
