disable (default)
enable

NOTE: When this flag is enabled, the tones processed override any incoming tones in the media stream. For example, when Accept Alert-Info is enabled, the

Spacevars

0	product

plays the tone specified in the Alert-info header of 180 ringing message overriding the inband tones included in the 180 ringing message.

NOTE: When using PSX in your network, enable the acceptAlertInfo flag from PSX's IP Signaling Profile. \

addPChargingFuncAddr

Set (enable) this flag to add the stored value of the PCFA header to a request or response.The PCFA header value is stored based on the flag.

disable (default)
enable

addPathServiceRoute

Enable this flag to allow

Spacevars

0	product

acting as P-CSCF or IBCF to add two Path headers in REGISTER request towards the Core (createPathHeader must be enabled) OR allow

Spacevars

0	product

acting as IBCF to add two Service-Route headers in 200 OK response for REGISTER towards the P-CSCF (createServiceRouteHeadermust be enabled).

disable (default)
enable

NOTE: When noServiceRouteHdrForEmergencyRegistration flag is enabled,

Spacevars

0	product

does not add Service-Route headers for emergency registrations even if addPathServiceRoute and createServiceRouteHeader flags are enabled.

aiToPemInterworking

This flag is used to interwork between PEM and AI headers and the other way. This flag is configured on the IP Signaling Profile.

The options are:

disabled(default)
enabled

If disabled, the SBC plays tone based on the LMSD format.

1	Flags {c}

Parameter Description

callHoldInterworking

Set flag to enable Call Hold Interworking service between ISUP and SIP. The service converts an ISUP call hold to an SIP call hold, or vice-versa. Call holds are invoked by ISUP or SIP/H.323 endpoints. When disabled, call hold indications are dropped.

disable (default)
enable

clearmodeForDataCalls

Set flag to enable the clearmode function for data calls.

disable – (default) If disabled for the SIP Egress call leg, legacy operation is signaled and payload type is assumed implicit (same on both sides). If disabled for the SIP Ingress call leg, legacy G.711 operation is accepted as well as Clearmode.
enable – If enabled for the SIP Egress call leg, Clearmode is sent using dynamic payload type. If enabled for SIP Ingress call leg, only Clearmode data calls are accepted.

contactTransparencyForIsFocusMediaTag

Enable flag to transparently pass Contact header for all requests and responses in outgoing message when "isFocus" parameter is received in Contact header.

disable (default)
enable

NOTE: This flag is configurable from an external PSX.

createPChargingVector

Enable flag to create a new PCharging-Vector header in outgoing message for INVITE and REGISTER messages. The PCharging-Vector header is also supported in SUBSCRIBE, OPTIONS, NOTIFY, MESSAGE, PUBLISH and REFER messages when received from same direction as REGISTER message. The P-Charging-Vector header contains the ICID value, ICID Generated at value and orig-ioi value. The string for orig-ioi value can be configured at egress trunk group.

disable (default)
enable

createPVisitedNetworkId

Enable flag to allow

Spacevars

0	product

acting as P-CSCF to insert a P-Visited-Network-ID Header in the egress REGISTER request with the P-Visited-Network-ID configured string.

disable (default)
enable

createPathHeader

Enable flag to create a new Path header in the outgoing REGISTER request.

disable (default)
enable

createServiceRouteHeader

Enable flag to create a new Service-Route header in the outgoing 200 OK response for REGISTER.

disable (default)
enable

NOTE: When noServiceRouteHdrForEmergencyRegistration flag is enabled,

Spacevars

0	product

does not add Service-Route headers for emergency registrations even if addPathServiceRoute and createServiceRouteHeader flags are enabled.

customizedSessionTimerBehavior

When enabled, the remote peer expects customer-specific session timer behavior. When disabled, the remote peer expects the standard session timer behavior.

disable (default)
enable

Command Parameters

Caption

0	Table
1	Flags {d}

Parameter Description

disableAlsoHeader

Enable this flag to allow

Spacevars

0	product

to ignore the Also header if received from the remote peer and

Spacevars

0	product

does not send the Also header to the remote peer. When disabled, the

Spacevars

0	product

uses the Also header for call forwarding as usual.

disable (default)
enable

disableHostTranslation

Use this flag to enable/disable host name translation. This applies to all URL style headers that require transparency and defines the processing that SBC is to apply to the host name portion of these headers before forwarding.

disable (default)
enable

disableMediaLockDown

Enable this flag to allow

Spacevars

0	product

to disable media lock-down by not sending SIP Re-INVITE/UPDATE messages in the following scenarios:

Multiple codecs are sent in the offer and multiple codecs (or their subsets) are received in the answer, and the call becomes transcoded.
Multiple codecs are sent in the offer and a single codec is received in the response.
Multiple codecs are sent in the offer and a single codec with codec attributes is received in the response.

If the result is a pass-through codec, and the most preferred codec in the answer (first codec in the list) is same as the selected codec, the

Spacevars

0	product

disables media lock-down by not informing the egress peer using a re-INVITE.

If the

Spacevars

0	product

offers both pass-through and transcoding codecs, the minimizeRelayingOfMediaChangesFromOtherCallLegAll flag effectively suppresses the re-INVITEs to peers when the peer answers with a single codec. However, if the peer has multiple codecs, the minimizeRelayingOfMediaChangesFromOtherCallLegAll flag in certain situations cannot suppress the re-INVITEs as a change in one of the common codecs is detected. In these situations, if the

Spacevars

0	product

’s most preferred codec matches the peer's most preferred codec, enable the disableMediaLockDown flag to suppress this Modify Offer initiated by the

Spacevars

0	product

to lock down the codec.

If this flag is disabled, the

Spacevars

0	product

sends a modify offer to lock down the codec.

disable (default)
enable

disableReferToUriParameters

By default, this flag is disabled thereby allowing parameters in the SIP URI Refer-To header to pass through to the outgoing INVITE URI. Enable this flag to prevent the parameters from passing through.

disable (default)
enable

discardReceivedReasonHeader

Enable flag to ignore cause code in received Reason header. When disabled, the

Spacevars

0	product

uses the cause code in the received Reason header.

disable (default)
enable

doNotIncludeSsAttributeInReInvite

Enable flag to prevent

Spacevars

0	product

from sending silence suppression (no a=silenceSupp is sent) in the SDP to the remote peer. When disabled, and when silence suppression is off, the

Spacevars

0	product

sends a=silenceSupp:off in the SDP to the remote peer.

disable (default)
enable

NOTE: a=silenceSupp:on is never sent to remote peer in current implementation when silence suppression is on.

Command Parameters

Caption

0	Table
1	Flags {e}

Parameter Description

enableDefaultPUIProcedures

Enable this flag to allow default PUI procedures on egress trunk group. Note that the Privacy 'Transparency' flag must be disabled to allow this feature.

disable (default)
enable

enableDialStringHandling

This flag is primarily used to enable/disable transparency of dial string (i.e username) received in request URI of INVITE message. Transparency does not occur, however, if PSX/ERE returns globalized or non-private called address. SBC performs dial string identification based on RFC 4967.

disable (default)
enable

endToEndBye

For SIP-to-SIP calls, enable flag to prevent

Spacevars

0	product

from issuing the 200 BYE on the side initiating the disconnect until the 200 BYE is received from the other leg. When disabled, the

Spacevars

0	product

issues the 200 BYE on the side initiating the disconnect regardless of whether a 200 BYE is received from the other leg.

disable (default)
enable

endToEndPrack

When this flag is enabled, SBC forwards the received reliable provisional response without generating PRACK locally. It waits for the PRACK from ingress peer to generate PRACK towards egress peer.

disable (default)
enable

NOTE: This flag must be enabled when both endpoints support PRACK and the 100rel header extension.

endToEndReInvite

When this flag is enabled, SBC forwards the Re-INVITEs received from one leg (with or without SDP) to the other leg.

disable (default)
enable

endToEndUpdate

When this flag is enabled, SBC forwards the Update (With SDP) received from one leg to the other leg.

disable (default)
enable

When enabled, port numbers are included with IP addresses in the From and To headers of SIP messages. When disabled, port numbers are not included with IP addresses.

disable (default)
enable

includeReasonHeader

When enabled, the

Spacevars

0	product

includes the Reason header in 18x, 4xx, 5xx, Cancel, and Bye messages in the forward direction. It is provisioned on the egress trunk group.

disable (default)
enable

includeSsAttributeInInitialInvite

Enable this flag to send the 'a=silenceSupp:off' in the Initial Invite SDP to the remote peer when Silence Suppression is OFF. When disabled, 'a=silenceSupp' is not sent in the Initial Invite SDP to the remote peer. Note that 'a=silenceSupp:on' is never sent to the remote peer in the Sonus implementation when Silence Suppression is ON.

disable (default)
enable

includeTransportTypeInContactHeader

This flag is used by an

Spacevars

0	product

configured for an external PSX.

When this flag is enabled, the

Spacevars

0	product

includes the Transport Type parameter in the Contact headers of 3XX responses. The PSX sends the value of this flag in a DIAMETER response to the SBC.

When this flag is disabled, the SBC does not include the Transport Type parameter.

disable (default)
enable

NOTE: Ensure passcompletecontactHeader flag is disabled (except for the REGISTER method) to obtain the desired behavior.

insertPAccessNetworkInfo

Enable flag to construct and send PANI with received location info.

disable (default)
enable

insertPeerAddressAsTopRouteHeader

When enabled, the

Spacevars

0	product

SIPE inserts the IP address of the next hop in the top route header of the egress INVITE. This is required when the

Spacevars

0	product

acts as a IMS BGCF proxy, and also supports SIPconnect compliance for direct inward dialing.

Command Parameters

Caption

0	Table
1	Flags {l}

Parameter Description

lockDownPreferredCodec

Enable this flag to maintain the most preferred codec of the leg on which it is enabled even if it requires transcoding. This feature also suppresses the re-INVITE triggered on the leg (on which it is enabled from the SBC) due to a MODIFY offer received from the other leg as part of mid-call codec modification.

disable (default)
enable

NOTE: This flag must be enabled in conjunction with minimizeRelayingOfMediaChangesFromOtherCallLegAll flag to produce desired results.

NOTE: When this flag is enabled, the flag “relayDataPathModeChangeFromOtherCallLeg” must also be enabled to propagate HOLD Modify Offers (any modify offer that changes the data-path-mode).

Command Parameters

Caption

0	Table
1	Flags {m}

Parameter Description

mapCauseLocation

Enable this flag to add the cause location is added to or retrieved from the SIP Reason header when mapping ISUP-to-SIP or SIP-to-ISUP signaling (you must also enable the Include Reason Header function). ISUP (and other protocols) indicate where in the network a call release was initiated from; this option enables the SIP Reason header to carry the cause location as well as the cause value. When flag is disabled, cause location mapping is off.

disable (default)
enable

mapSuspendResumeEventInPSvcInfoHeader

Enable this flag to map the suspend/resume event in the P-Svc-Info header. When disabled, the

Spacevars

0	product

does not map the suspend/resume event in the P-Svc-Info header.

disable (default)
enable

mapUuiInPSigInfoHeader

Enable this flag to map the UUI parameter into the SIP P-Sig-Info header. When disabled, the

Spacevars

0	product

does not map or include the UUI parameter.

disable (default)
enable

mimeCausePrecedeReasonHeaderCause

When enabled, the cause value is mapped from the MIME body of the incoming message based on the Q.1912 standard. When disabled, the cause value is mapped from the Reason header based on the RFC3398 standard

disable (default)
enable

minimizeRelayingOfMediaChangesFromOtherCallLegAll

The advertised Sonus SIP SDP is described as a set of capabilities that the

Spacevars

0	product

can receive. The

Spacevars

0	product

by default issues a Modify Offer ( re-INVITE, UPDATE) whenever it detects a change in receive capabilities. In certain scenarios, the Modify Offer can be perceived as redundant. Enabling this flag suppresses redundant Modify offers being sent from the

Spacevars

0	product

.

When enabled, the

Spacevars

0	product

suppresses modify offers that have no changes to the “common codecs” that impact the end-user experience. “Common codecs” are codecs that exist both in the initial offer and answer. Changes to common codecs imply changes to DTMF, packetization time, codec specific FMTP attributes and data-path-mode.

	noUserinfoInContactHeader <disable | enable>

Command Parameters

Caption

0	Table
1	Flags {n}

Parameter Description

noContentDisposition

The Content Disposition header format in SIP messages expected by the remote peer. When enabled, the remote peer expects no Content Disposition header. When disabled, remote peer expects the standard SIP message format which includes Content Disposition header.

disable (default)
enable

noPortNumber5060

Use this parameter to control whether port number 5060 is sent to the remote peer in the Request-URI of PRACK, ACK, and BYE messages.
When enabled, the outgoing SIP URI does not include port number 5060 (sip:user@host). In addition,

Spacevars

0	product

only sends out the Record-Route and Route headers of SIP request and response messages with the port number it receives, such that if the

Spacevars

0	product

does not receive a port number in Record-Route headers, the

Spacevars

0	product

does not send out a port number in the Record-Route and Route headers.

When disabled, the outgoing SIP URI includes port number 5060 (sip:user@host:5060). In addition, if SBC does not receive a port number in Record-Route headers of SIP request and response messages, the

Spacevars

0	product

inserts port number 5060 into the outgoing Record-Route and Route headers.

disable (default)
enable

NOTE: Enable this flag to allow DNS NAPTR/SRV lookups.

noServiceRouteHdrForEmergencyRegistration

When this flag is enabled,

Spacevars

0	product

does not add Service-Route headers for emergency registrations even if addPathServiceRoute and createServiceRouteHeader flags are enabled.

disable (default)
enable

noUserinfoInContactHeader

When this flag is enabled, the remote peer expects no userinfo component in the Contact header URI. When disabled, the remote peer expects the standard format of the Contact header, which includes the userinfo component.

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.

disable (default)

Example of SBC acting as IBCF:

INVITE (PCV1) --> SBC --> INVITE
200 OK (PCV1) <-- SBC <-- 200 OK
