Interworking
About Interworking
The VCS is able to act as a gateway between
SIP and H.323, translating calls from one
protocol to the other. This is known as
“interworking”.
By default, the VCS will act as a SIP-H.323 and
H.323-SIP gateway but only if at least one of
the endpoints is locally registered.
You can change this setting so that the VCS
will act as SIP-H.323 gateway regardless of
whether the endpoints involved are locally
registered.
You also have the option to disable
interworking completely.
Overview Configuring Interworking
Interworking options are configured via:
VCS Configuration > Protocols > Interworking • .
You will be taken to the Interworking page.
xConfiguration Interworking Mod • e
H.323 <-> SIP interworking mode
Determines whether or not the VCS will act as a gateway between SIP and H.323 calls.
Off : the VCS will not act as a SIP-H.323 gateway.
RegisteredOnly : the VCS will act as a SIP-H.323 gateway but only if at least one of the endpoints is
locally registered.
On : the VCS will act as SIP-H.323 gateway regardless of whether the endpoints are locally
registered.
!
We recommend that you leave this
setting as
RegisteredOnly (where
calls are interworked only if at least
one of the endpoints is locally registered).
Unless your network is correctly configured,
setting it to
On (where all calls can be
interworked) may result in unnecessary
interworking, for example where a call between
two H.323 endpoints is made over SIP, or vice
versa.

Calls for which the VCS is acting as an
SIP to H.323 gateway are traversal
calls. They will therefore require a
traversal call licence.
