Signaling
Access Class

Set parameter to "3GPP" to select GIBA security mechanism when a REGISTER message is received without specific security headers. The SBC validates Source IP Address against Via header IP Address and transparently passes UEs Via header in egress messages towards network entities. If REGISTER message is received with "sec-agree" in Proxy-Require header along with Auth headers, and no IP Sec profile is configured, the SBC rejects the message with "4xx Bad Extension" error response irrespective of the Access Class parameter value.

When GIBA security mechanism is selected and Via header is configured to pass transparently to egress leg, SBC inserts a “received” parameter with the source IP address of the PDU if the host portion of the UE’s Via header does not equate to the source IP address seen by the SBC.

Possible choices:

  • 3GPP – Select to enable GIBA security mechanism as explained above.
  • none – (default) SBC defaults to SIP Digest without TLS authentication.

    When this parameter is disabled for egress trunk group, SBC does not update the originating and terminating identities in outbound SIP message as per policy response from PSX.
  • enabled : When this parameter is enabled for ingress trunk group, SBC sends the originating and terminating identities URI information as separate fields in policy request to PSX. These originating and terminating identities URI information is rewritten as per rules configured in PSX and sent to SBC in policy response.

When this parameter is enabled, for egress trunk group, SBC updates the originating and terminating identities in outbound SIP message as per policy response from PSX.

For this feature to work, Rewrite Identities should be enabled on both ingress and egress SIP Trunk Groups.

Registration

Require Registration

This flag should be SUPPORTED when the associated trunk group is used for endpoints optionally requiring registration. Select any one of the option: none, required, requirednonpriority, supported, supported-group, required-group and required-group-nonpriority.

  • none – (default) No registration validation is required. 
  • required – Prevent unregistered IADs from making or receiving any calls. 
  • required-nonpriority – Prevent unregistered IADs from making or receiving non-priority calls. Since priority calls are exempt, unregistered endpoints are still allowed to make priority calls. 
  • supported – Accept registrations from unregistered endpoints when the associated trunk group is used for endpoints optionally requiring registration. If an endpoint is registered, then the registration data is used to send calls to that   endpoint instead of PSX route. 
  • supported-group – Accept registrations from unregistered users and from users whose user   names do not match with the stored URI in Registration Control Block. If an endpoint is registered, then the registration data is used to send calls to   that endpoint instead of PSX route.

  • required-group  – If this option is selected for an ingress IP trunk group in relation to a received call (e.g. call from IP-PBX towards AS) so that if the source IP address and port of the INVITE/OOD request do not match the source IP address and port of an existing registration in the zone, they are rejected. However, if the AOR does not match, but if the source IP Address and the port match to the existing registration in the zone, messages are accepted. If this option is selected for an egress IP trunk group in relation to a received call (e.g. call from AS towards IP-PBX), the user part check between registered AoR and Request-URI of the INVITE does not occur, and the call is accepted.
  • required-group-nonpriority – Use this option to prevent unregistered IADs from making or receiving non-priority calls. All emergency calls are allowed even if the source IP/port fails to fetch RCB.

Set Require Registration flag to ‘supported-group’ for the IP Peer on which surrogate registration functionality is being enabled.

Expires This is the time (in seconds) a SIP endpoint's registration session lasts before requiring re-registration. Specify time in seconds. Default is 3600 seconds.

Inside Expires
Minimum

This controls the initial expires value in a REGISTER relayed to a registrar. Specify time in seconds. Default is 3600 seconds.

Since the SBC expects an expires value greater than 540 seconds (9 minutes) from the registrar, do not set “insideExpiresMinimum” value less than 540 seconds. Ideally, set this value much higher (3600 seconds is recommended) to avoid overloading registrar with register refreshes.

When configuring surrogate registration, be sure to set the expires value of ingress trunk group toward IAD to the maximum default value of “3600”.

Include XOriginal Addr

Specifies whether the X Original Address Header need to go in REGISTER message or not.

If "Int Refresh Factor Max" is less than "Int Refresh Factor Min" or both "Int Refresh Factor Max" and "Int Refresh Factor Min" are set to 0, the random factors are ignored and the timeouts or the deadlines are calculated using a random number between x and x/2.

Ext Refresh Factor MinDefines the minimum factor for random number calculation for external refresh timeout. The range values from 0 to 1000 and the default value is 0.
Ext Refresh Factor Max

Defines the maximum factor for random number calculation for external refresh timeout. The range values from 0 to 1000 and the default value is 0.

If "Ext Refresh Factor Max" is less than "Ext Refresh Factor Min" or both "Ext Refresh Factor Max" and "Ext Refresh Factor Min" are set to 0, the random factors are ignored and the timeouts or the deadlines are calculated using a random number between x and x/2.

Auth PasswordPassword needed to create Authorization Digest or Proxy-Authorization headers for trunk group authentication. These credentials are used when replying to local authentication requests. The value ranges from 6 to 32 characters.  
Int Challenge Response

Enable this flag on the ingress IP Trunk Group (IPTG), respective to the request, to allow the SBC to reply locally to egress IPTG authentication challenges. If this flag is disabled, the SBC will not reply to authentication challenges locally even if credentials are configured on the egress IPTG.

  • Disabled (default)
  • Enabled  
Inc Internal Credentials

Enable this flag on the ingress IP Trunk Group, respective to the request, to allow egress IPTG authentication to be internally created using the authorization information in mid-dialogue without being challenged.

  • Disabled (default)
  • Enabled
If intChallengeResponse is disabled, incInternalCredentials is not used.


The SBC will not use IPTG credentials if a call originates from a surrogate originated peer even if intChallengeResponse is enabled on the ingress leg.

 

If IPTG authentication is configured for both ingress IPTG and IP Peer, the IP Peer configuration takes precedence. If you wish to use the flags configured on IPTG, the IP Peer must not be present in the configurations. Otherwise, the IP Peer flags default to 'disabled' state and take precedence over IPTG flags.

It can be configured only when mediaNat is enabled. Also, for egress trunk groups, learnNatForRtpOnly is applicable only if ‘dynamicLrbt’ is disabled. If ‘dynamicLrbt’ is enabled, NAPT learning happens on arrival of RTP packet till the call gets connected. After the call gets connected, ‘learnNaptForRtpOnly’ holds good even for egress Trunk Groups.

Ice Support

This parameter indicates the type of ICE method used for STUN packet check. The values are:

  • Ice Webrtc - This setting is used when inter-working with Webrtc Gateways, for example the Sonus WRTC Gateway or in situations when the SBC is presented with an ICE SDP from a WebRTC Enabled Endpoint.

    When configured for this mode, SBC acts as a generic ICE-Lite agent.

  • Ice Lync - This is used when inter-working with a Microsoft Lync 2010 or 2013 client.
  • Ice Full - This is used when inter-working with a full ICE client which requires a STUN connectivity check to be generated by the SBC in response to its own STUN connectivity check.

For MS Lync ICE (Ice Lync setting), keep-alive messages are sent only to RTP port.

Note

Sonus recommends to avoid configuring both Media Nat and ICE Support on the same Trunk Group because these configurations are independent mechanisms for solving NAT traversal issues. Because of of this, these configurations should not coexist on the same Trunk Group.

The parameter, Learn Nat For Rtp Only, does not apply to ICE and should not be enabled for the Trunk Group with ICE Support enabled.

Refer to SDP Support for a detailed description on Ice Support.
