Account x 🡪 Network Settings

DNS Mode

This parameter controls how the Search Appliance looks up IP addresses for hostnames.
There are four modes: A Record, SRV, NATPTR/SRV, Use Configured IP.
The default setting is “A Record”.
If the user wishes to locate the server by DNS SRV, the user may select “SRV” or “NATPTR/SRV”.
If “Use Configured IP” is selected, please fill in the three fields below:

If SIP server is configured as domain name, phone will not send DNS query, but use “Primary IP” or “Backup IP x” to send SIP message if at least one of them are not empty.

Phone will try to use “Primary IP” first. After 3 tries without any response, it will switch to “Backup IP x”, and then it will switch back to “Primary IP” after 3 re-tries.

If SIP server is already an IP address, phone will use it directly even “User Configured IP” is selected.

DNS SRV Fail-over Mode

The option will decide which IP is going to be used in sending SIP packets after IPs for the SIP server host are resolved with DNS SRV.

Register Before DNS SRV Failover

This option allows to choose the behavior for registering before DNS SRV Fail-over.
If set to “No”, a REGISTER request will not be initiated when a server failover occurred under DNS SRV mode.
If set to “Yes”, a REGISTER request will be initiated when a server failover occurred under DNS SRV mode.

Primary IP

Configures the primary IP address where the phone sends DNS query to when “Use Configured IP” is selected for DNS mode.

Backup IP1

Configures the backup IP1 address where the phone sends DNS query to when “Use Configured IP” is selected for DNS mode.

Backup IP2

Configures the backup IP2 address where the phone sends DNS query to when “Use Configured IP” is selected for DNS mode.

NAT Traversal

This parameter configures whether the NAT traversal mechanism is activated. Users could select the mechanism from No (Default), STUN, Keep-alive, UPnP, Auto or VPN.
If set to “STUN” and STUN server is configured, the phone will route according to the STUN server. If NAT type is Full Cone, Restricted Cone or Port-Restricted Cone, the phone will try to use public IP addresses and port number in all the SIP&SDP messages.
The phone will send empty SDP packet to the SIP server periodically to keep the NAT port open if it is configured to be “Keep-alive”. Configure this to be “No” if an outbound proxy is used. “STUN” cannot be used if the detected NAT is symmetric NAT. Set this to “VPN” if OpenVPN is used.

Support Rport (RFC 3581)

This option enables the utilization of symmetric response routing. When enabled, the "rport" field gets appended to the Via header in the SIP Request. The necessary data is then extracted from the SIP 200OK Response during a SIP Register operation, allowing the rewriting of SIP Contact information and its application in subsequent SIP Requests.
Enabled by Default.

Proxy-Require

A SIP Extension to notify the SIP server that the phone is behind a NAT/Firewall. Do not configure this parameter unless this feature is supported on the SIP server.

Use SBC

If set to “Enable”, “Tel:” will be used instead of “SIP:” in the SIP request. The default setting is “Disable”.

SIP Registration

Selects whether the phone will send SIP Register messages to the proxy/server. The default setting is “Yes”.

Unregister On Reboot

If set to “All”, the SIP user’s registration information will be cleared when the phone reboots. The SIP Contact header will contain “*” to notify the server to unbind the connection.
If set to “Instance”, the SIP user will be unregistered on current phone only. 
If set to “No”, the phone will not unregister the SIP account when rebooting.

SIP T2 Timeout

SIP T2 Timeout is the maximum retransmit time of any SIP request messages (excluding the INVITE message). The re-transmitting and doubling of T1 continues until it reaches the T2 value. Default is 4 seconds.

SIP Transport
