Abstract
VOIP Architecture is fully integrates communications by enabling data, voice, and video to be transmitted over a single network infrastructure using standards-based IP.
VoIP is a technology that allows IP networks to be used for voice applications, such as telephony, voice instant messaging, and teleconferencing.
VOIP are uses H.323, MGCP, SIP, and SCCP call signaling and call control protocols.
Digital signal processing DSPs is used for process digital voice traffic. DSPs on a router provide stream-to-packet signal processing functionality that includes voice compression
Convert telecom Egypt call center from traditional telephony (Circuit switch Ericsson BPX MDllO or MX-ONE) to Voice over Internet Protocol by implement VOIP on Ericsson MDllO or MX-ONE using Digital Residential Gateway DRG and Ericsson Enterprise Branch Gateway EEBG and by implement VOIP on Cisco Unified Communications Manager Express (CME) to allows a voice-enabled router’s to carry voice traffic such as telephone calls and faxes, over an Internet.
