Descriptions

Outbound Proxy

It is used to configure the IP address or the domain name of the primary outbound proxy, media gateway, or session border controller. It is 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

It is used to configure the 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

It is used to set which DNS service will be used to look up IP address for SIP server’s hostname. It can be selected from the dropdown list:

• A Record
• SRV
• NATPTR/SRV.

If the device needs DNS SRV resource, in which case the DNS server responds with more than one result, it should be set to “SRV” or “NATPTR/SRV”.

The default setting is “A Record”.

NAT Traversal

It is used to configure the NAT traversal mechanism used on the device. It can be selected from the dropdown list:

• NAT NO
• STUN
• Keep-alive
• uPnP
• Auto
• VPN
• TURN

If the outbound proxy is configured and used, it can be set to “NAT NO”.

If set to “STUN” and STUN server is configured, the device will periodically send STUN message 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.

If set to “Keep-alive”, the device will send the STUN packets to maintain the connection that is first established during 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 device.

If the device needs to use OpenVPN to connect to host server, please set it to “VPN”.

If the firewall and the SIP device behind the firewall are both able to use UPnP, it can be set to “UPnP”. Both parties will negotiate the port used to allow SIP packets to go through.

If it is set to “TURN”, the protocol is designed to be used as part of the ICE (Interactive Connectivity Establishment) approach to NAT Traversal.

The default setting is “Keep-alive”.

Proxy-Require

It is used to add the Proxy-require header in the SIP message. It is used to indicate proxy-sensitive features that must be supported by the proxy. Do not configure this parameter unless this feature is supported on the SIP server.

Parameters

Descriptions

SIP Registration

It is used to set if allowing the device to send SIP Register messages to the proxy/server. The default setting is “Yes”.

Unregister Before New Registration

It clears the SIP user’s registration information when the GVC3210 reboots. The SIP REGISTER message will contain “Expires: 0” to unbind the connection.

Three options are available:

• If it is set to “All”, the SIP user’s registration information will be cleaned when the device starts pre-registration after rebooting. The SIP Contact header will contain “*” to notify the server to unbind the connection.
• If set to “Instance”, the device only cleans the current SIP user’s info.
• If set to “No”, the device will not unregister the SIP account when rebooting.

The default setting is “Instance”.

Register Expiration (Min.)

This option is used to enable or disable session timer on the GVC3210 side when server side can provide both session timer UPDATE or session audit UPDATE.

The default setting is “Yes”.

Session Expiration (s)

It is used to configure the device’s SIP session timer period (in seconds). It enables SIP sessions to be periodically “refreshed” via a SIP request (UPDATE, or re-INVITE). If there is no refresh via an UPDATE or re-INVITE message, the session will be terminated once the session interval expires. Session Expiration is the time (in seconds) where the session is considered timed out, provided no successful session refresh transaction occurs beforehand. The default setting is 180 with a valid range from 90 to 64800.

Min-SE (s)

It is used to configure the minimum session expiration timer (in seconds) if the device acts as a timer refresher. The default setting is 90. The valid range is from 90 to 64800.

UAC Specify Refresher

It is used to set the party which will refresh the active session if the device makes outbound calls. If it is set to “UAC” and the remote party does not support Refresher feature, the device will refresh the active session. If it is set to “UAS”, the remote party will refresh it. If it is set to “Omit”, the header will be omitted so that it can be selected by the negotiation mechanism. The default setting is “Omit”.

UAS Specify Refresher

It is used to set the party which will refresh the active session if the device receives inbound calls. If it is set to “UAC”, the remote party will refresh the active session.

The default setting is “No”.

Caller Request Timer

This is used to set the caller party to act as refresher. If set to “Yes” and both parties support session timers, the device will enable the session timer feature when it makes outbound calls. The SIP INVITE will include the content “refresher=uac”.

The default setting is “No”.

Callee Request Timer

This is used to set the callee party to act as refresher. If set to “Yes” and both parties support session timers, the device will enable the session timer feature when it receives inbound calls. The SIP 200 OK will include the content “refresher=uas”.

The default setting is “No”.

Force Timer

It is used to activate the session timer feature on the device. If it is set to “Yes”, the device will use the session timer even if the remote party does not support this feature. If it is set to “No”, the device will enable the session timer only when the remote party supports this feature. To turn off the session timer, select “No”.

The default setting is “No”.

Enable 100rel

It is used to activate the PRACK (Provisional Acknowledgment) method. This option is very important to support PSTN internetworking. PRACK improves the network reliability by adding an acknowledgement system to the provisional Responses (1xx). If set to “Yes”, the device will respond to the 1xx response from the remote party.

The default setting is “No”.

Caller ID Display

It is used to set the header tag from the SIP INVITE message for the Caller ID display. If it is set to Auto, the device will use one of the available headers in the priority hierarchy of P-Asserted Identify Header, Remote-Party-ID Header and From Header. If it is set to “From Header”, it will use the From Header information for the Caller ID. If it is set to “Disabled”, all the incoming calls Caller ID will be displayed with “Unavailable”. The default setting is “Auto”.

Use Privacy Header

Controls whether the Privacy header will present in the SIP INVITE message or not, whether the header contains the caller info. When set to “default”, the Privacy Header will show in INVITE only when “Huawei IMS” special feature is on. If set to “Yes”, the Privacy Header will always show in INVITE. If set to “No”, the Privacy Header will not show in INVITE. The default setting is “Default”.

Use P-Preferred-Identity Header

It is used to set if the P-Preferred-Identity Header will be presented in the SIP INVITE message. If set to “default”, the P-Preferred-Identity Header will be omitted in SIP INVITE message when “Huawei IMS” special feature is active.
