Dont Send Facility Message | Set this flag to prevent sending Facility messages to endpoints that do not tunnel and have difficulty processing Facility messages. The options are:
NOTE: Enabling this flag on the ingress leg may result in no media establishment for H.323 calls with discrete H.245 (no H.245 tunneling) due to H.245 socket collision. To avoid this issue, either disable this flag or ensure the H.245 signaling port address (actual hex value) associated with this setting is greater than its peer. |
Refuse Fast Start Proposal | When this flag is set,

Ingress Ip Attributes - Flags
Parameter | Description |
|---|---|
Sip181Supported | Enable flag to allow the SBC to support 'SIP 181 Call Is Being Forwarded' messages in the backward direction on the ingress trunk group. The options are:
|
Sip182Supported | Enable flag to allow the SBC to support SIP 182 Queued messages in the backward direction on the ingress trunk group. The options are:
|
Map Called Party Category In PSig Info Header | Enable flag to map Called Party Category parameter to outgoing SIP P-Sig-Info header. The P-Sig-Info header is a customer-specific SIP header used to convey ISUP information in SIP messages. The options are:
|
No Sdp In 180 Supported | By default, the Unable to show "metadata-from": No such page "_space_variables" includes SDP in outbound 180 messages. When enabled, the Unable to show "metadata-from": No such page "_space_variables" does not include SDP in outbound 180 messages. It converts the 180 message to a 183 message instead. When disabled the Unable to show "metadata-from": No such page "_space_variables" includes SDP in outbound 180 messages. The options are:
|
Registration Expires in Expires Header | Controls what the Unable to show "metadata-from": No such page "_space_variables" signals back to a peer when it has received a REGISTER message from that peer. When enabled, Unable to show "metadata-from": No such page "_space_variables" inserts the Expires header in the message. When disabled, Unable to show "metadata-from": No such page "_space_variables" does not insert the Expires header. The options are:
|
Send183On Initiating Disconnect Treatment | Enable flag to send a 183 message on initiating a disconnect treatment. The options are:
|
Send Sdp In200Ok If18x Reliable | Enable flag to send SDP in final 200 OK response messages when provisional 18x responses are reliable. The options are:
This flag only applies to 200 OK sent for an early offer. |
Send Sdp In Subsequent18x | Enable the flag to send SDP in subsequent 18x response messages after the SBC sends the answer in non-reliable provisional response to the INVITE. When this parameter is in disabled state, the SBC does not send SDP in the subsequent 18x response messages. The options are:
|
Send TLSConnection Failure Response | Enable flag to report TLS connection failure and respond with '408 Request timeout' message and Warning header instead of '504 Server timeout'. The options are:
|
Supress 183For3xx Redirect Response | Do not send 183 without SDP upon receiving 3xx Redirect Response. The options are:
|
Supress 183Without Sdp | Never send 183 without SDP. The options are:
See SDP Support topic for details of |
Set-cut-through-indication-in-OBCI | Enable flag to set the BIT-H of BCI parameters in the outgoing 18x message to allow the node to temporarily halt call set-up and play tones or announcements, or both, and collect additional in-band information from the calling user before routing the call further. The options are:
|
Send Updated SDPin200Ok | Enable this flag to send any SDP update before the answer (i.e., when the SDP changes between the last response sent and a 200 OK) on the ingress side in the 200 OK without using a reInvite. An SDP update is required at the ingress side if any change occurs in the SDP between 18x and 200 OK on the egress leg.
