| Parameter | Description |

sdpOlineOnlyCompares | When enabled, the SBC checks only the o-line when comparing SDPs. When disabled, the SBC checks the entire SDP body when comparing SDPs. |

Configuration options: NOTE: Refer to SDP Support for examples of the above behavior. |
sendDirectMediaInfoInSdpAttribute | Enable flag to send direct media information in the SDP attribute X-DMI. NOTE: The 'directMediaAllowed' flag must be disabled on the associated trunk group. |
sendOnlyPreferredCodec
| Enable this flag on Answer side to send a single preferred codec in an Answer for an Initial Offer or Re-Invite. Enable flag on Offer side to send the most preferred codec in a re-INVITE offer. When disabled, the SBC sends all possible pass-through codecs in the route Packet Service Profile when the call is answered. This flag is used primarily in pass-through cases where more than one pass-through codec is possible. When generating an answer, the SBC chooses the most preferred codec based on the ordered list created by Send Route Preference (SRP)/Honor Remote Preference (HRP). Note that when this flag is disabled SBC sends all possible pass-through codecs in the answer or the Route Packet Service Profile when generating a re-INVITE offer. For offers generated by the SBC, especially in HOLD/RESUME cases, only the most preferred codec is sent in a re-INVITE offer when this flag is enabled. |
sendPtimeInSdp | Enable flag to allow the SBC to send a=ptime in the SDP. |
sendRTCPBandwidthInfo
| Enable flag to send the RR and RS bandwidth information, as well as "b=RR:" and "b=RS:" in the SDP offer. |
sendRtcpPortInSdp | When enabled, the adds the attribute,a=rtcp:<rtcpPort> to the audio and video m lines in the outgoing SDP (Rtcp port mentioned will be SBC RTP port + 1). |
sessionTimerRefreshUpdate | Enable flag to control session timer refresh method with SIP peers via UPDATE messages. When disabled, the sends INVITE messages. NOTE: This flag is only accessible when the flag "minimizeRelayingOfMediaChangesFromOtherCallLegAll" is set to "enable". |
setAcceptHeaderToApplicationSdpOnly | Use flag to specify the Accept header format in SIP messages expected by the remote peer. When enabled, the remote peer receives a short Accept header format containing the application/SDP value only. When disabled, the remote peer receives the standard Accept header format containing all of the standard parameters. |
setOlineDash | Specifies the SDP O-Line format in the SDP of SIP messages expected by the remote peer. When enabled, the remote peer receives an O-Line format in which the username component is set to a "-" (dash). When disabled, the remote peer receives the standard O-Line format containing all of the O-Line parameters, including the username. |
setSessionVersionZero | Enable flag to set the session version to zero in the o-line of the outbound SDP. When disabled, the assigns a session version randomly. |
setSlineDash | Specifies the SDP S-Line format in the SDP of SIP messages expected by the remote peer.disable (default) – Remote peer receives standard S-Line format containing all of the S-Line parameters.enable – Remote peer receives a short S-Line format containing a dash only (s=-).
|
skipPsxQueryForRefer | Set flag to skip the ERE query for Refer flag. |
storePChargingFuncAddr | Set this flag to store the values received in the PCFA header in a request or response. The stored value is added to a subsequent response or a request based on the flag addPChargingFuncAddr. |
storePChargingVector | When this flag is enabled, the SBC stores the P-Charging-Vector (PCV) received in requests. When the response is forwarded back, the stored PCV is inserted and sent. If the SBC receives the PCV when this flag is disabled, the SBC ignores the PCV and does not log the CDR. Example of SBC acting as IBCF: INVITE (PCV1) --> SBC --> INVITE
200 OK (PCV1) <-- SBC <-- 200 OK |
storePathHeader | Set this flag to locally store (cache) a Path header received in an incoming REGISTER request. |
storeServiceRouteHeader | Set this flag to locally store (cache) a Service-Route header received in an incoming 200 OK response to REGISTER. |
supportSCSCFRestorationProcedures | SBC acting as P-CSCF rejects a request with 504 (Server Time-out) response carrying MIME body of type application/3gpp-ims+xml, if SBC does not receive any response to the request from S-CSCF network or the next hop address is blacklisted as part of ARS (Address Reachability Service) service (see IMS Restoration Procedures for addtional details). |
suppressMinSeIfNotReceived | Enable flag to add Min-SE header to re-INVITEs/UPDATEs only if it exists in the previous offer/answer. When this flag is disabled, Min-SE is always added to session refreshes. |
