Parameter

Description

Convert Progress To Alert

Set this flag to convert Progress messages to Alert messages when communicating to endpoints that have difficulty with Progress messages. The options are:

  • Disable (default)
  • Enable
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:

  • Disable (default)
  • Enable

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, 

Spacevars
0product
does not include FastStart proposal in early media calls. Instead, it relies on H.245 procedure to complete media setup. When cleared, 
Spacevars
0product
always includes fast start proposal in SETUP message for early media calls. The options are:

  • Disable (default)
  • Enable
Send Fast Start Response In Cp

Send Updated SDPin200OkEnable

...

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.
  • Disable (default)- The SBC sends the last sent SDP in 200 OK and updates it using Re-INVITE.
  • Enable - The SBC sends updated SDP on the ingress side in 200 OK for INVITE.
