prefixes from 250 to 279.

You can select Unknown, Private or E.164 Public.
The default is Unknown.
Select the H.225/Q.931 Number Plan assigned to this entry.
• If you selected Unknown as the Number Type, you can select Unknown.
• If you selected Private as the Number Type, you can select Unknown, Level 0
Regional (Local), Level 1 Regional, Level 2 Regional or PISN Specific.
• If you selected E.164 Private as the Number Type, you can select Unknown,
International, National, Network Specific, Subscriber or Abbreviated.

Number fields.
Note: The Type of Number information is used only for registration of this number where
the VoIP Gateway is the destination endpoint. The Type of Number encoding used when
dialing from this VoIP Gateway is set in the number manipulation tables for Telephone to
IP calls.
See Appendix A, “Numbering and Dial Plans,” on page 147 , for more information about
the Type of Number fields.

The Save Configuration option is useful for trying out a new configuration.

new configuration, save the changes to non-volatile memory. If you are not happy
with the new configuration, do not save the changes to non-volatile memory and
remove power from the VoIP Gateway. The VoIP Gateway will return to the previous
configuration.
