Determines what happens when the VCS receives a SIP search that originated as an H.323 search,
destined for a system that was located via this zone. The default is Off.
Off: a SIP OPTION or SIP INFO message will be sent to the system.
On: searches will be responded to automatically, without being forwarded to the system.
This option should normally be left as the default Off. However, some systems such as

Microsoft Office Communications Server (OCS) 2007 will not accept SIP OPTION messages,
so for these zones this should be set to On. If you do 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 will generate 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. The default is On.
On: SIP INVITEs with no SDP will be generated and sent to systems located via this zone.
Off: SIP INVITEs will be generated and a pre-configured SDP will be inserted before the INVITEs are
sent to this system.
In most cases this option should normally be left as the default On. However, some systems
!
such as Microsoft OCS 2007 will 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

SIP poison mode
On: SIP requests sent to systems located via this zone will be 'poisoned' such that if they are
received by this VCS again they will be rejected.
Off: SIP requests sent out via this zone that are received by this VCS again will not be rejected; they
will be processed as normal.
SIP SDP attribute line limit mode
Determines whether requests containing SDP sent out to this zone will have the length of
lines restricted.
On: the length will be truncated to the maximum length specified by the
length
setting.
Off: the length will not be truncated.

some systems such as Microsoft OCS 2007 cannot handle attribute lines longer than 130
