Supplementary services within an IP environment are provided via Q.931 and H.323. IP Office provides the
same rich services as enjoyed within a traditional network environment. Our standards based approach allows
interoperability within mixed vendor networks.

The basic supplementary service features supported by H.323 on IP Office to IP Office IP trunk links are listed
below.

· Basic call set up (voice).

· Call Hold (local).

· Call Transfer (local).

· Called/Calling Name.

· Called/Calling Number.

 

Additional features can be added through the use of IP Office Small Community Networking (see the following
section).

On IP trunks to non-IP Office systems the Supplementary Service will depend on those also supported by the
non-IP Office system.
