Zones Zone [1..200] DNS 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 1 DNS Interworking SIP EmptyInviteAllowed: On
Zones Zone [1..200] DNS Interworking SIP Video DefaultBitrate: <64..2048>
Specifies which video bitrate to use when empty INVITEs are not allowed.
Default: 384
Example:
xConfiguration Zones Zone 1 DNS Interworking SIP Video DefaultBitrate: 384
Zones Zone [1..200] DNS 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 1 DNS Interworking SIP Video DefaultCodec: H263
Zones Zone [1..200] DNS 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 1 DNS Interworking SIP Video DefaultResolution: CIF
Zones Zone [1..200] DNS SIP Poison Mode: <On/Off>
SIP requests sent out this zone will be 'poisoned' such that if they are received by this VCS again they will be rejected.
Default: Off
Example:
xConfiguration Zones Zone 1 DNS SIP Poison Mode: Off
Zones Zone [1..200] DNS SIP SDP Attribute Line Limit Length: <80..65535>
If SIP SDP attribute line limit mode is set to On, sets the maximum line length of a=fmtp SDP lines.
Default: 130
Example:
xConfiguration Zones Zone 1 DNS SIP SDP Attribute Line Limit Length: 130
Zones Zone [1..200] DNS SIP SDP Attribute Line Limit Mode: <On/Off>
Determines whether requests containing SDP sent out to this zone will have the length of a=fmtp lines restricted.
On
: the length will be truncated to the maximum length specified by the SIP SDP attribute line limit length setting.
Off: the length will not be truncated.
Default: Off
Example:
xConfiguration Zones Zone 1 DNS SIP SDP Attribute Line Limit Mode: Off
