Grandstream Networks HT503 FXS/FXO Manual De Usuario

 

sounds. ON is the period of ringing (“On time” in ‘ms’) while OFF is the period of 
silence. In order to set a continuous tone, OFF should be zero. Otherwise it will ring ON 
ms and a pause of OFF ms and then repeat the pattern. 
 
Here is an example for the configuration of the dial tone for North America: 
f1=350@-13,f2=440@-13,c=0/0; 
Syntax: f1=freq@vol, f2=freq@vol, c=on1/off1-on2/off2-on3/off3; [...]  
(Note: freq: 0 - 4000Hz; vol: -30 - 0dBm) 

If set to “Yes”, the configuration update via keypad is disabled. 

Disables the voice prompt configuration.  Default is “No.” 

Disables the Direct IP Call function.  Default is “No.” 

URL or IP address of the NTP server, Used to synchronize the date/time. 

The IP address or URL of syslog server, especially useful for ITSP  

Select the ATA to report the log level. Default is NONE. The level is either one of 
DEBUG, INFO, WARNING or ERROR. Syslog messages are sent based on the 
following events: 

• 

product model/version on boot up (INFO level) 

• 

NAT related info (INFO level) 

• 

sent or received SIP message (DEBUG level) 

• 

SIP message summary (INFO level) 

• 

inbound and outbound calls (INFO level) 

• 

registration status change (INFO level) 

• 

negotiated codec (INFO level) 

• 

Ethernet link up (INFO level) 

• 

SLIC chip exception (WARNING and ERROR levels) 

• 

memory exception (ERROR level) 

The Syslog uses USER facility. In addition to standard Syslog payload, it contains the 
following components: GS_LOG: [device MAC address][error code] error message 

 Ex. May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000] Ethernet link is up 

This is a special feature that enables the user to create a text file backup of your 
existing configuration. 

When set to yes the FXS port is activated. 

This field contains the URL string or the IP address (and port, if different from 5060) of 
the SIP proxy server. e.g., the following are some valid examples:  sip.my-voip-
provider.com, or sip:my-company-sip-server.com, or 192.168.1.200:5066 

IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border 
Controller. Used by ATA for firewall or NAT penetration in different network 
environment. If symmetric NAT is detected, STUN will not work and ONLY Outbound 
Proxy will work.  

User can select UDP or TCP or TLS. 

This setting decides whether the NAT traversal mechanism is activated. It should be 
set to “Yes” if the device is behind a NAT router. If no outbound proxy is configured, a 
STUN server needs to be set to activate STUN detection mechanism. Usually ITSP will 
provide these settings.  If this field is set to “Yes”, then the device will periodically send 
a dummy UDP packet to the SIP server to pinhole the NAT. 

User account information, provided by VoIP service provider (ITSP), usually has the 
form of digit similar to phone number or actually a phone number. This field contains 
the user part of the SIP address for this phone.  e.g., if the SIP address is 
sip:my_user_id@my_provider.com, then the SIP User ID is: my_user_id.   
Do NOT include the preceding “sip:” scheme or the host portion of the SIP address in 
this field.
