(This flag is for specific call flows and is not intended for generic use)

• disabled (default)
• enabled

• none – (default)
• required
• supported

• disabled (default)
• enabled

sipArsProfile

The name of the SIP ARS (Address Reachability Service) profile.

defaultJipProfile – The default name of the SIP JIP profile to associate in egress and ingress SIP Trunk Groups.

Enable this flag to allow insertion of JIP parameter in SIP trunk group ingress and egress headers.

• disabled (default)
• enabled

• none – When set to "none", the

  does not add SIP precondition attributes in SDP of outgoing request even if attributes are present in the SDP of incoming requests.
• required – Use this option to add SIP precondition attributes in SDP of outgoing request even if attributes are NOT present in the SDP of incoming requests. If precondition attributes are added by the

  , the local preconditions are set to ‘met’ and remote preconditions are set to ‘not-met’.
• supported – (default) Use this option to ensure backward compatibility behavior. Use this option to add SIP precondition attributes in SDP of outgoing request only if attributes are present in the incoming request.
  

Enable the flag to send new SIP requests mid-dialog to the previously-learned IP address before performing any SRV DNS query.

The previously-learned IP address is updated in the following cases:

1. SBC receives an INVITE from the peer.
2. SBC receives re-INVITE from the peer.
3. SBC receives 200 OK response to INVITE sent.

4. SBC receives 200 OK response to re-INVITE sent.

If a time-out occurs on requests sent to previously-learned Active IP address mid-dialog, a SRV DNS look up is performed.

• disabled (default)
• enabled

Adaptive NAT pinhole learning parameters.

• maxTcpPinholeTimer – Defines upper limit of the pinhole timeout for TCP in seconds. (range: 60-65535 / default = 600).
• maxUdpPinholeTimer – Defines the upper limit of the pinhole timeout for UDP in seconds.  (range: 60-65535 / default = 180). 
• reLearningInterval – Interval in hours at which the pinhole timeout is relearned. (range: 1-240 / default = 24). 
• state– Enables/disables the adaptive nat pinhole timeout learning process for devices behind NAT. 
  • disabled (default)

• serverReflexivePrefixLength – The length (in bits) of the prefix for server reflexive IP address (range: 0-32 / default = 16).

• state – Administrative state of iceSourceAddressFilterPriority.

  • disabled
  • enabled (default)

INFO:

The filtering mechanism is applicable to the following RTP address types:

• • IPV4 Server Reflexive Address (for this address type, filtering is based on the provisioned Server Reflexive Prefix Length)
  • IPV4 Relay Address
  • IPV6 Relay Address
  • IPv6 Host Address

This parameter indicates the type of ICE method used for STUN packet check.

• none (default)


• iceWebrtc – Select this attribute for WebRTC Gateway interworking. For example, using 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, the SBC acts as a generic ICE-Lite agent.

• iceLync – Select this attribute when interworking with a Microsoft Lync 2010 or 2013 client.

  • iceKeepaliveTimer – Set Keep-Alive timer value, in seconds, for MS-Lync ICE to prevent network loss of STUN message exchanges. (range: 1-60 / default = 15)

• iceFull – Select this attribute when interworking with a full ICE client requiring the generation of a STUN connectivity check by the SBC in response to its own STUN connectivity check. 

  • iceKeepaliveTimer – Set Keep-Alive timer value, in seconds, for full-ICE to prevent network loss of STUN message exchanges. (range: 1-60 / default = 15)

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

Refer to Configuring SBC for WRTC for ICE-Lite configuration best practices.

Use this flag to specify if SBC initiates the TCP connection for ICE Lync.

• active – Use this option for the SBC to initiate the TCP connection when connected to internal-facing trunk groups where the peer is not behind the NAT. Also, use this option when working with certain Unified Communication (UC) servers such as Acano which expect the peer to initiate the TCP connection. This is only supported when there are no NATs between the SBC and the UC server.
• passive (default) – The SBC waits for the peer to initiate the TCP connection. Use this option when working directly with Lync endpoints.

NOTE: The iceSupport parameter must be set to IceLync to configure this flag.

Refer to Configuring SBC and LYNC in Media Environment for configuration details.

• disabled (default) 

• enabled

NOTE: The flag mediaNat must be enabled to use this flag.

NOTE: Do not enable learnNatForRtpOnly for SIP trunk groups with iceSupport enabled because it does not apply to ICE NAT traversal.

Specifies the whether or not NAT/NAPT support is required for media. 

• disabled (default) 
• enabled

• ipAddress – IPv4 address. 
• prefixLength – Value from 0-128 specifying the number of bits representing the network part of ipAddress.

• disabled (default)
