SIP Server

The URL or IP address, and port of the SIP server.

This is provided by your VoIP service provider (ITSP).

Secondary SIP Server

The URL or IP address, and port of the SIP server. When configured, GSC3570 will register to both Primary and Secondary SIP Server. If Primary SIP Server is not reachable then the GSC3570 will use Secondary SIP Server for GSC3570 services (including making/receiving calls).

Outbound Proxy

IP address or Domain name of the Primary Outbound Proxy, Media Gateway, or Session Border Controller. It is used by the GSC3570 for Firewall or NAT penetration in different network environments.

IP address or Domain name of the Secondary Outbound Proxy which will be used when the primary proxy cannot be connected.

SIP User ID

User account information provided by your VoIP service provider (ITSP).

It is usually in the form of digits like phone number or a phone number.

Notes:

Users can register an account with a SIP user ID that carries “@”. (For example: “111@test.com”, so the GSC3570 will register the account as “111@test.com” instead of 111)

The server domain will not be included in the SIP from header.

Authenticate ID

SIP service subscriber’s Authenticate ID used for authentication.

It can be identical to or different from the SIP User ID.

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:

Primary IP:

Backup IP 1.

Backup IP 2.

If SIP server is configured as domain name, GSC3570 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.

GSC3570 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, GSC3570 will use it directly even “User Configured IP” is selected.

Primary IP

Configures the primary IP address where the GSC3570 sends DNS query to when “Use Configured IP” is selected for DNS mode.

Backup IP1

Configures the backup IP1 address where the GSC3570 sends DNS query to when “Use Configured IP” is selected for DNS mode.

Backup IP2

Configures the backup IP2 address where the GSC3570 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 GSC3570 will route according to the STUN server. If NAT type is Full Cone, Restricted Cone or Port-Restricted Cone, the GSC3570 will try to use public IP addresses and port number in all the SIP&SDP messages.

The GSC3570 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.

Proxy-Require

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

Account x 🡪 SIP Settings 🡪 Basic Settings

TEL URI

If the GSC3570 has an assigned PSTN phone 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.

Unregister on Reboot

Allows the SIP user’s registration information to be cleared when the GSC3570 reboots. The SIP REGISTER message will contain “Expires: 0” to unbind the connection. Three options are available: The default setting is “No”.

If set to “All”, the SIP user’s registration information will be cleared when the GSC3570 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 GSC3570 only.

If set to “No”, the GSC3570 will not unregister the SIP account when rebooting.

Jitter Buffer Type

Selects either Fixed or Adaptive for jitter buffer type, based on network conditions. The default setting is “Adaptive”.

Jitter Buffer Length

Selects jitter buffer length from 100ms to 800ms, based on network conditions. The default setting is “300ms”.

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.

G723 Rate

Note: For some network environment, the default setting “720P” might be too high that causes no video or video quality issue during video call. In this case, please change “H.264 Image Size” to “VGA” or “CIF” and change “Video Bit Rate” to “384kbps” or lower.

The default setting is 720P.

H.264 Profile Type

Selects the H.264 profile type from the dropdown list.

Baseline Profile

Main Profile

High Profile

BP/MP/HP (Default Setting)

Note: Lower levels are easier to decode, but higher levels offer better compression. Usually, for the best compression quality, choose “High Profile”; for playback on low-CPU machines or mobile devices, choose “Baseline Profile”.

If “BP/MP/HP” is selected, all three profiles “Baseline Profile” “Main Profile” and “High Profile” will be used for negotiation during video decoding to achieve the best result. This is usually used in video conference when there is higher requirement on the video.

Video Bit Rate

Configures the bit rate for video call. It can be selected from the dropdown list. The default setting is 2048 kbps. The valid range is from 32 – 2048 kbps.

Note: The video bit rate can be adjusted based on the network environment. Increasing the video bit rate may improve video quality if the bandwidth is permitted. If the bandwidth is not permitted, the video quality will decrease due to packet loss.

For some network environment, the default setting “720P” might be too high that causes no video or video quality issue during video call. In this case, please change “H.264 Image Size” to “VGA” or “CIF” and change “Video Bit Rate” to “384kbps” or lower.

H264 Payload Type

Specifies the H.264 codec message payload type format. The default setting is 99.

The valid range is from 96 to 127.

Enable Proxy Video Compatibility
