Zones Zone [1..1000] Neighbor Interworking SIP Audio DefaultCodec: <G711u/G711a/G722_48/
G722_56/G722_64/G722_1_16/G722_1_24/G722_1_32/G722_1_48/G723_1/G728/G729/AACLD_48/
AACLD_56/AACLD_64/AMR>
Specifies which audio codec to use when empty INVITEs are not allowed.
Default: G711u
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Audio DefaultCodec: G711u
Zones Zone [1..1000] Neighbor Interworking SIP EmptyInviteAllowed: <On/Off>
Determines whether the VCS will generate a SIP INVITE message with no SDP to send to 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 will be generated and sent to this neighbor.
Off: SIP INVITEs will be generated and a pre-configured SDP will be inserted before the INVITEs are sent to this
neighbor.
Default: On
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP EmptyInviteAllowed: On
Zones Zone [1..1000] Neighbor Interworking SIP Encryption EncryptSRTCP: <Yes/No>
Determines whether or not the VCS offers encrypted SRTCP in calls to this zone.Info: the VCS will send an INFO
request.
Default: No
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Encryption EncryptSRTCP:
No
Zones Zone [1..1000] Neighbor Interworking SIP Search Strategy: <Options/Info>
Determines how the VCS will search for SIP endpoints when interworking an H.323 call.
Options: the VCS will send an OPTIONS request.
Info: the VCS will send an INFO request.
Default: Options
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Search Strategy: Options
Zones Zone [1..1000] Neighbor Interworking SIP Video DefaultBitrate: <64..65535>
Specifies which video bitrate to use when empty INVITEs are not allowed.
Default: 384
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Video DefaultBitrate: 384
Zones Zone [1..1000] Neighbor Interworking SIP Video DefaultCodec:
<None/H261/H263/H263p/H263pp/H264>
Specifies which video codec to use when empty INVITEs are not allowed.
Default: H263
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Video DefaultCodec: H263
Zones Zone [1..1000] Neighbor Interworking SIP Video DefaultResolution:
<None/QCIF/CIF/4CIF/SIF/4SIF/VGA/SVGA/XGA>
Specifies which video resolution to use when empty INVITEs are not allowed.
Default: CIF
Example: xConfiguration Zones Zone 3 Neighbor Interworking SIP Video DefaultResolution:
CIF
