2.5 VoiceBlue Next Connection to VoIP
Since
communicates using the SIP only, this subsection outlines
2N VoiceBlue Next
®
solutions for its interconnection with networks working with the H.323 signalling
protocols.
can be used either in the Point-to-Point or
2N VoiceBlue Next
®
Point-to-Multipoint mode with the SIP Proxy server.
SIP / H.323 Interconnection
SIP–based devices cannot communicate with H.323.supporting devices directly, but
through a SIP/H.323 gateway. This gateway transfers signalling messages from/to the
protocols. Using the RTP for multimedia data transmission, the SIP and H.323 protocols
can go on communicating directly when the SIP/H.323 gateway connection is
established. Thus, the SIP/H.323 gateway helps integrate
into
2N VoiceBlue Next
®
the existing H.323 environment.
Point-to-Point Configuration
2N VoiceBlue Next
®
can communicate with just one SIP VoIP phone or device (a
VoIP gateway, e.g.) in the PTP (Point-to-Point) mode. The IP address of the opposite
party is always selected as the Proxy server IP address in
for
2N VoiceBlue Next
®
this mode.
The
PTP configuration is often used for testing purposes before
2N VoiceBlue Next
®
implementation into the VoIP network. Refer to the figure below for the PTP scheme.
Tip
If you set the incoming SIP Proxy IP address to '0.0.0.0' in the
configuration, the GSM gateway will
2N VoiceBlue Next
®
receive calls from any VoIP device.
