2.5 2N® VoiceBlue MAX Connection to VoIP
Since communicates using the SIP only, this subsection outlines 2N VoiceBlue MAX
®
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 MAX
®
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 MAX
®
the existing H.323 environment.
Point-to-Point Configuration
2N VoiceBlue MAX
®
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 this mode. 2N VoiceBlue MAX
®
The PTP configuration is often used for testing purposes before 2N VoiceBlue MAX
®
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 2N
®
configuration, the GSM gateway will receive calls from VoiceBlue MAX
any VoIP device.
