Parameters Description

adaptiveLearning

N/A

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)
- enabled

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.

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

title	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

	iceSourceAddressFilterPriority_note

iceSupport

N/A

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.

iceTcpRole

N/A

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 .

See 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.

disabled (default)
enabled

Panel

borderColor	#fff2cc
bgColor	#fffdf6

Note

The flag mediaNat must be enabled to use this flag.

Panel

borderColor	#fff2cc
bgColor	#fffdf6

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.

disabled (default)
enabled

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 qualifiedPrefixtable, 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.

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

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.

disabled (default)
enabled

Include Page

	No_NAT_for_IPv6
	No_NAT_for_IPv6

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).
