Default
Applicable to
Zone profile
Determines the configuration of the Advanced settings for this zone. The options are:
Default: the VCS uses the default values for these settings.
Preconfigured profiles: alternatively, choose one of the preconfigured profiles to automatically use the appropriate settings required for
connections to that type of system. The options include:
Default: the VCS uses the default values for these settings.
Preconfigured profiles: alternatively, choose one of the preconfigured profiles to automatically use the appropriate settings required for
connections to that type of system. The options include:
•
Microsoft Office Communications Server 2007 (see
for full
details on how to configure the VCS and OCS to enable the two systems to work together)
•
Cisco Unified Communications Manager
•
Nortel Communication Server 1000
•
TANDBERG Advanced Media Gateway
Custom: lets you configure each Advanced setting individually. These settings are listed in the remainder of this table below.

automatically
responded to
Determines what happens when the VCS receives a SIP search that originated as an H.323 search.
Off: a SIP OPTION or SIP INFO message is sent.
On: searches are responded to automatically, without being forwarded.
This option should normally be left as the default Off. However, some systems such as Microsoft Office Communications Server (OCS)
2007 do not accept SIP OPTION messages, so for these zones it must be set to On. If you change this to On, you must also configure
pattern matches to ensure that only those searches that actually match endpoints in this zone are responded to. If you do not, the search
will not continue to other lower-priority zones, and the call will be forwarded to this zone even if it cannot support it.

Empty INVITE allowed
Determines whether the VCS generates a SIP INVITE message with no SDP to send via this zone. INVITES with no SDP mean that the
destination device is asked to initiate the codec selection, and are used when the call has been interworked locally from H.323.
On: SIP INVITEs with no SDP are generated.
Off: SIP INVITEs are generated and a pre-configured SDP is inserted before the INVITEs are sent.
In most cases this option should normally be left as the default On. However, some systems such as Microsoft OCS 2007 do not accept
invites with no SDP, so for these zones this should be set to Off.

The settings for the pre-configured SDP are configurable using the

commands. They should only be changed on the advice of Cisco customer support.
