Configuring DNS Zones

SIP mode

Determines whether SIP calls will be allowed to this zone.

H.323 mode

Determines whether H.323 calls will be allowed to this zone.

Full details of how to use and configure DNS zones is given in URI Dialing.

Empty INVITE allowed

Determines whether the VCS will generate a SIP INVITE messages which has no SDP to send to this zone.

On: SIP INVITEs with no SDP will be generated and sent to this neighbor.

Off: SIP INVITEs with no SDP will be generated but a pre- configured SDP will be inserted before they are sent to this neighbor. The defaults for the SDP are:

Note: 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.

Searches are automatically responded to

Determines what happens when the VCS receives a search destined for this zone.

Off: a SIP OPTION message will be sent to the zone.

On: searches will be responded to automatically, without being forwarded to the zone.

Note: In most cases this option should normally be left as the default Off. However, some systems such as Microsoft 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.
