IMPORTANT
Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.
Refer to the SBC SIP Transparency Implementation Guide for additional information.
Note
Prior to release 7.1, when the To-Header Transparency flag is set, the Request-URI is sent transparently even when the globalization flag of the Number Globalization Profile is enabled. In this case, the To-Header Transparency does not send the called number in the Request-URI locally.
Henceforth, the SBC supports globalizing the Request-URI by enabling globalization for the called number and enabling the To-Header Transparency flag. Thus, the Request-URI called number is not transmitted transparently to the egress leg (To-Header transparency flag will not affect Request-URI globalization). Note that Request-URI globalization is independent of the To-Header Transparency. This functionality applies to all scenarios where To-Header transparency is enabled, such as:
- Redirection scenarios
- Refer scenario
- Interaction with Undo LNP
- Modifying hostname of reqURI
To View and Edit Transparency Flags
On SBC main screen, go to Configuration > System Provisioning > Category: Trunk Provisioning > Ip Signaling Profile > Common Ip Attributes > Transparency Flags. The Transparency Flags window is displayed.

The following fields are displayed:
Transparency Flags Parameters
Parameter | Description |
|---|---|
Accept Contact Header | Set flag to allow P-CSCF to transparently pass the received Accept-Contact Header.
|
Alert Information Header | Set this flag to transparently copy the ALERT INFO header from the ingress SIP INVITE method to the egress SIP INVITE message.
|
Authcode Headers | Enable this flag to transparently copy the WWW Authentication header for SIP 401/407 response messages or SIP Authorization/Proxy Authorization headers.
You must enable |
Pass Complete Contact Header | Enable flag at egress IPSP (with respect to message direction) to copy the Contact header and its parameters from the ingress message and insert in the egress message.
|
Contact Header | Set flag to transparently pass the Contact Header Flag in egress leg with respect to the message direction.
|
Errror Info | Enable this flag to transparently copy the Error-Info header from the ingress leg to the egress leg.
|
From Header | Enable this flag to transparently copy the userinfo@host component of the FROM header from the ingress SIP INVITE message to the egress SIP INVITE messag
Even when this flag is enabled, the IP port information is not included unless the "Include IP Ports in From and To Headers" flag, elsewhere in this IP Signaling Profile, is also enabled. |
History Info | Controls History-info header transparency in SIP INVITE messages. When enabled, the SBC passes the History-Info header transparently from the ingress message to the egress message. When disabled, the SBC does not copy the history-info. Provision this flag on the egress leg with respect to the message direction.
|
Max Forwards Header | Enable this flag to decrement the value in Max-Forwards header by 1 for requests traversing through the SBC. By default (disable), the SBC populates the Max-Forwards header with the value configured in Max Fwds Default (default value is 70).
|
Mwi Body | Enable flag to transparently copy the MWI body from the incoming message to the outgoing message for INVITE, REGISTER, BYE, INFO, OPTIONS, NOTIFY, REFER, and SUBSCRIBE. Provision this flag on the egress leg with respect to message direction.
|
P Access Network Info Header | Enable flag to transparently pass the p-Access-Network-Info (PANI) header from ingress to egress.
Enable this flag when Unable to show "metadata-from": No such page "_space_variables" is configured as P-CSCF node. |
P Called Party ID | Set flag to transparently pass the P-Called-Party-ID header from ingress to egress call leg.
|
P Charging Vector Header | When enabled, the Unable to show "metadata-from": No such page "_space_variables" transparently copies the P-Charging-Vector header from the ingress message to the egress message. When disabled, the SBC does not copy the header. PCharging- Vector header transparency is supported in INVITE, REGISTER, SUBSCRIBE, OPTIONS, MESSAGE, PUBLISH, NOTIFY, REFER, and INFO messages.
|
P Early Media | Controls P-Early Media header transparency in INVITE or non-100 RESPONSE requests and their responses if they are relayed. When enabled, the SBC transparently copies the P-Early Media header from the incoming message to the outgoing message. When disabled, the PEarly- Media header is not copied to the egress leg. Provision this flag on egress leg with respect to message direction.
|
P Visited Network IDHeader | Enable flag to pass the P-Visited-Network-ID header transparently to the egress leg.
|
Path Header | Enable flag to transparently copy the Path header from the ingress SIP message to the egress SIP message.

|
Reason Header | When enabled, the ingress Reason header value is passed through unchanged.
|
Referred By Header | When enabled, the SBC transparently copies the Referred-By Header (in INVITE requests/responses) from the incoming message to the outgoing message. When cleared, the Referred-By Header is not copied. Provision this flag on the egress leg (with respect to the message direction).
