User=phone: “User=GAC2570” parameter will be attached to the Request-Line and “From” header in the SIP request to indicate the E.164 number. If set to “Enable”.
Enabled: “Tel:” will be used instead of “sip:” in the SIP request.
Please consult your carrier before changing this parameter. Default is “Disabled”.
Network Settings
Outbound Proxy
Configures the IP address or the domain name of the primary outbound proxy, media gateway, or session border controller. It’s used by the device for firewall or NAT penetration in different network environments. If a symmetric NAT is detected, STUN will not work and only an outbound proxy can provide a solution
Secondary Outbound Proxy
Sets IP address or domain name of the secondary outbound proxy, media gateway, or session border controller. The device will try to connect the Secondary outbound proxy only if the primary outbound proxy fails.
DNS Mode
Defines which DNS service will be used to lookup the IP address for SIP server’s hostname. There are three modes: A Record SRV NATPTR/SRV To locate the server by DNS SRV set this option to “SRV” or “NATPTR/SRV”. The default setting is “A Record”.
Maximum Number of SIP Request Retries
Sets the maximum number of retries for the device to send requests to the server. In DNS SRV configuration, if the destination address does not respond, all request messages are resent to the same address according to the configured retry times. Valid range: 1-10. The default setting is 2.
Note: This option is available when DNS Mode is set to SRV or NAPTR/SRV only.
DNS SRV Failover Mode
The option will decide which IP is going to be used in sending subsequent SIP packets (ex: Register refresh requests) after the list of IPs for SIP server host is resolved with DNS SRV.
Default (prefer server with lowest SRV priority):
The device will always prefer to send SIP requests to the available server having the lowest priority, and in case it’s down it contacts the next one, but once the server having the lowest priority is UP again, the device will switch over to this one.
Saved one until DNS TTL (Stay on responding IP until DNS timeout):
In this mode, the device will resolve DNS SRV records and tries to send the request to the server having the lowest priority and if it doesn’t respond, it will move on to the next IP until one of the servers responds, once this happens the device will keep contacting this responding IP until DNS timeout (30 minutes) before starting over.
Saved one until no response (Stay on responding IP until its failure):
In this mode, the device will send SIP requests to the last responding IP, and it doesn’t failover/switchover to the next one until this responding server is down.
Failback follows failback expiration timer:
When selected, the device will send all SIP messages to the current failover SIP server or Outbound Proxy until the failback timer expire server is down.
Note: This option is available when DNS Mode is set to SRV or NAPTR/SRV only.
Register Before DNS SRV Fail-over
When this feature is enabled (default), the device will register using the outbound proxy when the SIP server is failed to get the registration.
Note: This option is available when DNS Mode is set to SRV or NAPTR/SRV only.
NAT Traversal
Specifies which NAT traversal mechanism will be enabled on the device. It can be selected from the dropdown list:
NAT NO: If the outbound proxy is configured and used, it can be set to “NAT NO”.
STUN: If set to “STUN” and the STUN server is configured, the device will periodically send STUN messages to the STUN server to get the public IP address of its NAT environment and keep the NAT port open. STUN will not work if the NAT is symmetric type.
Keep-alive: If set to “Keep-alive”, the device will send the STUN packets to maintain the connection that is first established during the registration of the device. The “Keep-alive” packets will fool the NAT device into keeping the connection open and this allows the host server to send SIP requests directly to the registered GAC2570.
Auto: When set to “Auto,” the device uses various techniques, including STUN (Session Traversal Utilities for NAT), TURN (Traversal Using Relay NAT), or ICE (Interactive Connectivity Establishment), to establish and maintain connections across NAT boundaries.
OpenVPN: If it needs to use OpenVPN to connect host server, it needs to set it to “VPN”. The default setting is “Keep-alive”.
The Default NAT Traversal mechanism is set to “Auto”
Proxy-Require

DTMF
Specifies the mechanism to transmit DTMF (Dual Tone Multi-Frequency) signals.
There are 3 supported modes: in audio, RFC2833, or SIP INFO.
• In audio, which means DTMF is combined in the audio signal (not very reliable with low-bit-rate codecs);
• RFC2833, which means to specify DTMF with RTP packet. Users could know the packet is DTMF in the RTP header as well as the type of DTMF.
• SIP INFO, which uses SIP INFO to carry DTMF. The defect of this mode is that it’s easy to cause desynchronized of DTMF and media packet if the SIP and RTP messages are required to be transmitted respectively.
The default setting is “RFC2833”.
DTMF Payload Type
Configures the RTP payload type that indicates the transmitted packet contains DTMF digits. Valid range is from 96 to 127. Default value is 101.

Voice Frames Per TX
Configures the number of voice frames transmitted per packet. When configuring this, it should be noted that the “ptime” value for the SDP will change with different configurations here. This value is related to the codec used and the actual frames transmitted during the in-payload call. For end users, it is recommended to use the default setting, as incorrect settings may influence the audio quality.
The default setting is 2.
RTP Settings
SRTP Mode
Sets if the device will enable the SRTP (Secured RTP) mode. It can be selected from dropdown list:
Disable
Enabled but not forced
