In this section:
Use this object to specify parameters associated with various enhanced services and features for this SIP trunk group.
CLI commands are case-sensitive and must be entered exactly as shown in this guide. Objects and profiles with names that differ only in case are considered distinct objects.
For example, the following trunk groups are three distinct trunk group entities: trunkgroup1, TRUNKGROUP1, TrunkGroup1. It is strongly recommended to avoid such naming conventions, and to also adopt a standard naming convention when initially defining your configuration.
Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core 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.
As a best practice, always use UPPERCASE for trunk group names.

NAT Traversal Parameters
Parameters | Length/Range | Description |
---|---|---|
adaptiveLearning | N/A | Adaptive NAT pinhole learning parameters.
|
iceSourceAddressFilterPriority | N/A | Enable this parameter for the SBC to prioritize the processing of STUN packets matching the source addresses received in the candidate lines of the ICE SDP received from the peer during the STUN connectivity check phase.
Note
The filtering mechanism is applicable to the following RTP address types:
Note
When ICE Source Address Filtering is enabled, STUN packets received during the connectivity check phase that do not match the addresses sent by the peer are still processed, but at a reduced rate. This allows the SBC to learn of the presence of Peer Reflexive Candidates through STUN. This has no impact during a stable call when only packets received from the learned source address are processed and the remaining are dropped by default. |
iceSupport | N/A | This parameter indicates the type of ICE method used for STUN packet check.
Note
For MS Lync ICE ( Note
Ribbon 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. Refer to Configuring SBC for WRTC for ICE-Lite configuration best practices. |
iceTcpRole | N/A | Use this flag to specify if SBC initiates the TCP connection for ICE Lync.
Note
The Refer to Configuring SBC and LYNC in Media Environment for configuration details. |
learnNatForRtpOnly | N/A | Enable flag to learn media NAT from the first RTP packet only. If disabled, media NAT is learned from any first packet received. For egress trunk groups, this flag is applicable only if dynamicLRBT flag is disabled. If dynamicLRBT is enabled, NAPT learning occurs on arrival of RTP packet until the call is connected, at which point learnNatForRtpOnly applies even for egress trunk groups.
Note
The flag
Note
Do not enable learnNatForRtpOnly for SIP trunk groups with iceSupport enabled because it does not apply to ICE NAT traversal. |
mediaNat | Specifies the whether or not NAT/NAPT support is required for media.
Ribbon 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.
| |
disableMediaNatIfSameMediaAndSigIp | N/A | Enable this flag to disable Media NAT if Media and Signaling IP addresses are identical.
|
outboundTcpKeepaliveTimer | 0-32767 | The NAT outbound keep-alive timer (in seconds) for SIP over TCP (default = 240) |
outboundUdpKeepaliveTimer | 0-32767 | The NAT outbound keepalive timer (in seconds) for SIP over UDP (default = 60) |
qualdifiedPrefix | N/A | Set of IP network media and signaling prefixes that an address must match to be considered for NAT handling. If there are no entries in qualifiedPrefix table, the endpoint is treated as existing behind a NAT device. As a result, the SBC considers requests from all IP addresses to be behind a NAT device.
|
secureMediaNatPrefix | 0-32 | Use this parameter to match up to 'N' bits of the network IPv4 address obtained from signaling. If set to "0", feature is disabled, and no match of network IP address will occur. (default = 0) |
signalingNat | N/A | This indicates whether or not NAT/NAPT support is required for signaling.
|
tcpKeepaliveTimer | 15-65535 | This NAT TCP keep-alive timer sets the registration refresh rate (in seconds) for SIP over TCP. (default = 240). |
udpKeepaliveTimer | 15-65535 | This NAT UDP keep-alive timer sets the registration refresh rate (in seconds) for SIP over UDP. (default = 60). |
