SIP User ID

It is used to configure the user account information, provided by your VoIP service provider (ITSP). It’s usually in the form of digits similar to phone number or actually a phone number.

SIP Authentication ID

It is used to configure the SIP service subscriber’s Authenticate ID used for authentication. It can be identical to or different from the SIP User ID.

SIP Authentication ID

It is used to configure the SIP service subscriber’s Authenticate ID used for authentication. It can be identical to or different from the SIP User ID.

SIP Authentication Password

It is used to configure the account password required for the device to authenticate with the ITSP (SIP) server before the account can be registered. After saving, it will appear as hidden for security purpose.

Voice Mail Access Number

This parameter allows you to access voice messages by entering voice mail or dialing access number. On the device, the users can select LCD menu🡪Applications🡪Voice Mail and click on the account to dial out to voicemail portal.

Display Name

It is used to configure the SIP server subscriber’s name (optional) that will be used for Caller ID display. The configured content will be included in the From, Contact and P-Preferred-Identity headers of SIP INVITE message.

Tel URI

If the device has an assigned PSTN telephone number, this field should be set to “User=Phone”. Then a “User=Phone” parameter will be attached to the Request-Line and “TO” header in the SIP request to indicate the E.164 number. If set to “Enable”, “Tel:” will be used instead of “SIP:” in the SIP request. The default setting is “Disable”.

Settings/SIP/Network

Parameters

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’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

It is used to configure the IP address or the 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 SUTN 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-Required 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.

Settings/SIP/SIP

Parameters

Descriptions

Session Expiration (s)

It is used to configure the device’s SIP session timer. 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. If it is set to “UAS” and the remote party does not support refresh feature, the device will refresh it. The default setting is “UAC”.

Force INVITE

It is used to set the SIP message type to refresh the session. If it is set to “Yes”, the Session Timer will be refreshed by using the SIP INVITE message. Otherwise, the device will use the SIP UPDATE or SIP OPTION message. 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.

Use Actual Ephemeral Port in Contact with TCP/TLS

It is used to set the port information in the Via header and Contact header of SIP message when the device uses TCP or TLS. If set to “No”, these port numbers will use the permanent listening port on the device. Otherwise, they will use the ephemeral port for the particular connection. The default setting is “No”.

Symmetric RTP

It is used to enable the symmetric RTP mechanism. If set to “Yes”, the device will use the same socket/port for sending and receiving the RTP messages. Default is “No”.

RTP IP Filter

It is used to configure whether to filter received RTP packets. The options are “Disable”, “IP Only” and “IP and Port”. The default setting is “Disable”.

This setting can be used with “Symmetric RTP”. Please see below:

  • Symmetric RTP = No, RTP IP Filter = Disable

The device sends RTP packets to the IP:Port included in SDP and accepts RTP packets from any address.

  • Symmetric RTP = Yes, RTP IP Filter = Disable

The device sends RTP packets to the IP:Port where the RTP packets come from and accepts RTP packets from any address.

  • Symmetric RTP = No, RTP IP Filter = IP Only

The device sends RTP packets to the IP:Port included in SDP and only accepts RTP packets from the IP in the SDP.

  • Symmetric RTP = Yes, RTP IP Filter = IP Only

The device sends RTP packets to the IP:Port where the RTP packets come from and only accepts RTP packets from the IP in the SDP.

  • Symmetric RTP = Yes, RTP IP Filter = IP and Port

Settings/SIP/Codec

Parameters

Descriptions

DTMF

It is used to set the parameter to specify the mechanism to transmit DTMF (Dual Tone Multi-Frequency) signals. There are 3 supported modes:

  • In audio: DTMF is combined in the audio signal (not very reliable with low-bit-rate codecs).

  • RFC2833: 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: Use SIP INFO to carry DTMF. The disadvantage 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 transmitted respectively.

The default setting is “RFC2833”.

DTMF Payload Type

It is used to configure the RTP payload type that indicates the transmitted packet contains DTMF digits. The valid range is from 96 to 127. The default setting is “101”.

Preferred Vocoder

It lists the available and enabled audio codecs for this account. Users can enable the specific audio codecs by moving them to the Selected box and set them with a priority order from top to bottom. This configuration will be included with the same preference order in the SIP SDP message. The codec option includes “PCMU”, “PCMA”, “Opus”, “G.722”, “G.722.1”, “G.722.1c”.

Codec Negotiation Priority

It is used to configure the codec negotiation sequence when the GVC3200/GVC3202 is acted as a callee. If set to “Caller”, the device will negotiate codec by SDP codec sequence from the received SIP INVITE message. If set to “Callee”, the device will negotiate codec according to the codec priority configuration on the device itself. The default setting is “Callee”.

Silence Suppression

It is used to set the silence suppression/VAD feature. If it is set to “Yes”, when silence is detected, a small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. If set to “No”, this feature is disabled. The default setting is “No”.

Voice Frames Per TX

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 in payload during the call. e.g.: if set to 2 and the first codec is G.729 or G.711, the “ptime” value is 20ms for the SDP. If the TX exceeds the maximum allowable value, the device will use and save the maximum allowed value according to what the first codec is. For end users, it is recommended to use the default setting, as incorrect settings may influence the audio quality. The default setting is “2”.

G.722.1 Rate

It is used to select encoding rate for G.722.1 codec. It supports 24kbps or 32kbps. The default setting is “24kbps encoding rate”.

G.722.1 Payload Type

It is used to configure payload type for G.722.1 codec. The valid range is 100-126. The default setting is “104”.

Opus Payload Type

It is used to configure payload type for Opus codec. The valid range is 96-126. The default setting is “123”.

Use First Matching Vocoder in 200OK SDP

If set to “Yes”, the device will use the first matching vocoder in the sent 200OK SDP as the codec. The default setting is “No”.

Enable RFC5168 Support

If set to “Yes”, the RFC5168 mechanism will be enabled for video call. RFC5168 allows SIP party to request the sender to refresh its video frame in H.264, or refresh the full picture in VP8. The default setting is “Yes”.

Enable Video FEC

If enabled, the video sender will temporarily allocate part of the bandwidth to one data channel to send FEC data to system, thus to improve the video quality the receiver gets. Enabling this function will take up part of bandwidth and reduce call rate. The default setting is “Yes”.

Video FEC Mode

If set to 0, FEC is not sent by separate port. If set 1, FEC is sent by separate port. Default setting is 0.

FEC Payload Type

It is used to configure FEC payload type. The range is 96-127. The default setting is 120.

Enable FECC

If set to “Yes”, You can control the camera of the opposite side for video call, but the opposite site must support FECC, and allow remote control on its local camera. The default setting is “Yes”.

FECC H.224 Payload Type

It is used to configure FECC H.224 payload type. The valid range is from 96 to 127. The default value is 125.

H.264 Payload Type

It is used to configure the H.264 codec message payload type format. The default setting is 99. The valid range is from 96 to 127.

Packetization-mode

The packetization mode can be set to 0, 1 or Auto. When it’s set to 0 or 1, the INVITE will include packetization mode value as 0 or 1. If it’s set to Auto, the INVITE will include both 0 and 1, and the packetization mode value is a result of negotiation between the endpoint and the server. Default setting is 1.

H.264 Image Size

Provisioning and Configuration File Download

Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP or HTTP/HTTPS. The “Config Server Path” is the TFTP, HTTP or HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be the same or different from the “Firmware Server Path”. A configuration parameter is associated with each particular field on the web configuration page. A parameter consists of a Capital letter P and 2 to 4-digit numeric numbers. i.e., P2 is associated with the “Admin Password” in the Web GUI🡪Maintenance🡪Web/SSH Access page. For a detailed parameter list, please refer to the corresponding firmware release configuration template in the following link: http://www.grandstream.com/support/tools

When the GVC3200/GVC3202 boots up, it will issue TFTP or HTTP request to download a configuration XML file named “cfgxxxxxxxxxxxx” followed by “cfgxxxxxxxxxxxx.xml”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab” or “cfg000b820102ab.xml”. If downloading “cfgxxxxxxxxxxxx.xml” file is not successful, the provision program will download a generic cfg.xml file. The configuration file name should be in lower case letters.

For more details on XML provisioning, please refer to the following document:

https://documentation.grandstream.com/knowledge-base/sip-device-provisioning-guide/
