Description
Default
Applicable to
SIP UDP/BFCP filter
mode
Determines whether INVITE requests sent to this zone filter out UDP/BFCP. This option may be required to enable interoperability with
SIP devices that do not support the UDP/BFCP protocol, so this must be set to
On
for connections to a Cisco Unified Communications
Manager.
On
: any media line referring to the UDP/BFCP protocol is replaced with TCP/BFCP and disabled.
Off
: INVITE requests are not modified.
Off
Neighbor zones
DNS zones
SIP Duo Video filter
mode
Determines whether INVITE requests sent to this zone filter out Duo Video. This option may be required to enable interoperability with SIP
devices that do not support Duo Video, so this must be set to
On
for connections to a Cisco Unified Communications Manager.
On
: the second video line in any outgoing INVITE request is removed.
Off
: INVITE requests are not modified.
Off
Neighbor zones
DNS zones
SIP record route
address type
Controls whether the VCS uses its IP address or host name in the record-route or path headers of outgoing SIP requests to this zone.
IP
: uses the VCS's IP address.
Hostname
: uses the VCS's
Local host name
(if it is blank the IP address is used instead).

SIP Proxy-Require
header strip list
A comma separated list of option tags to search for and remove from Proxy-Require headers in SIP requests received from this zone.
None
Neighbor zones
Include address record Determines whether, if no NAPTR (SIP) or SRV (SIP and H.323) records have been found for the dialed alias via this zone, the VCS will then
query for A and AAAA DNS records before moving on to query lower priority zones. If A and AAAA records exist at the same domain for
systems other than those that support SIP or H.323, this may result in the VCS believing the search was successful and forwarding calls to
this zone, and the call will fail.
On
: the VCS queries for A or AAAA records. If any are found, the VCS will not then query any lower priority zones.
Off
: the VCS will not query for A and AAAA records and instead will continue with the search, querying the remaining lower priority zones.
Off
