Leaving a Message to an Extension
For further information on all the services supported by IP Extensions, please refer to
the IPV20 Series User's Guide.
An IPV20 extension supports IP extensions via its IP services. Thus IP extensions
can be supported behind ADSL. To enable this the system supplies NAT/STUN
support.
During IP connections to a VPN, the IP extension applications act as if they were
connected locally. IP port routing is not required.
IP Lines can be selected so as to support the H323 and SIP protocols. The system
can include lines supporting the SIP and H323 protocols at the same time.
IP Lines can be used to build IP connections (Tie-Lines) between PBX's. They can
also be used to connect to a private operator's IP lines or to Proxy
Servers/GateKeepers throughout the company.
After IP Lines have been defined via the ComSer interface, line groups are similarly
created for the other lines groups, the routes are defined and then put into service.
