®
Point–to–Point mode that uses 2N VoiceBlue MAX .
Point–to–Multipoint Configuration
Point–to–Multipoint is a classical scheme of a distributed VoIP network with one or
more SIP Proxy servers (VoIP gateway). The SIP Proxy server is a software PBX (or a
standard PBX extended with VoIP services), which is responsible for all VoIP signalling.
®
Multiple source devices (VoIP phones, e.g.) and multiple target devices ( 2N
VoiceBlue MAX , e.g.) can be used in this mode. An internal routing algorithm (Least
Cost Router, LCR) of your SIP Proxy is used for routing outgoing GSM and other calls in
®
this mode. Calls to GSM networks can be routed via the 2N VoiceBlue MAX gateway
s. All SIP signalling is governed by the SIP Proxy server and the subsequent voice
stream is based on the Point–to–Point RTP.
