Tip
 If you set the incoming SIP Proxy IP address to „0.0.0.0‟ in the 2N ®
VoiceBlue Next configuration, the GSM gateway will receive calls from any
VoIP device.
All calls outbound to GSM are routed to the 2N ® VoiceBlue Next gateway in the Point-
to-Point mode that uses 2N ® VoiceBlue Next.
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 Next, 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 Next
gateways. All SIP signalling is governed by the SIP Proxy server and the subsequent
voice stream is based on the Point-to-Point RTP.
