Grandstream Networks HT503 FXS/FXO Benutzerhandbuch

 

dials a number.  If set to “Yes”, an INVITE is sent using the dial-number collected thus 
far.  Otherwise, no INVITE is sent until the “(Re-)Dial” button is pressed or after about 5 
seconds have elapsed.  The “Yes” option should be used ONLY if there is a SIP proxy 
configured and the proxy server supports 484 Incomplete Address response.  
Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error).   
Note: This feature is NOT designed to work with and should NOT be enabled for 
direct IP-to-IP calling. 

Sets the prefix added to each dialed number. 

This allows users to configure the # key as the “Send” (or “Dial”) key.  If set to “Yes”, “#” 
will send the number.  In this case, this key is essentially equivalent to the “Dial” key.  If 
set to “No”, the “#” key can be included as part of a number. 

Dial Plan Rules: 
 

1.  Accept Digits: 1,2,3,4,5,6,7,8,9,0  
 
2.  Grammar: x - any digit from 0-9;   

a.  xx+ - at least 2 digit number;  
b.  ^ - exclude;   
c. 

[3-5] - any digit of 3, 4, or 5;   

d.  [147] - any digit 1, 4, or 7;   
e.  <2=011> - replace digit 2 with 011 when dialing   

• 

Example 1: {[369]11 | 1617xxxxxxx} –  
Allow 311, 611, 911, and  any 10 digit numbers of leading digits 1617   

• 

Example 2: {^1900x+ | <=1617>xxxxxxx} –  
Block any number of leading digits 1900 and add prefix 1617 for any dialed 7 digit 
numbers 

• 

Example 3: {1xxx[2-9]xxxxxx | <2=011>x+} –  
Allow any length of number with leading digit 2 and 10 digit-numbers of leading 
digit 1 and leading exchange number between 2 and 9;  If leading digit is 2, 
replace leading digit 2 with 011 before dialing   

3.     Default: Outgoing - {x+} 

Default is “No.”  When set to “Yes” a SUBSCRIBE for Message Waiting Indication will 
be sent periodically. 

When set to “Yes”, the “From” header along with Privacy and P_Asserted_Identity 
headers in outgoing INVITE messages will be set to anonymous, blocking Caller ID. 

Default is “No.”  If set to “Yes”, incoming calls with anonymous Caller ID will be rejected 
with a 486 busy message. 

Default is “Standard.”  Choose the selection to meet some special requirements from 
Softswitch vendors. 

The HT503 supports 5 different Vocoder types including 

1.  G.711 A/µ law,  (Displayed as PCMA/PCMU) 
2. G.723.1, 

 

3.  G.726 (Supports bit rates 16, 24, 32, and 40)  
4. G.729A/B/E, 

 

5. iLBC 

Users can configure Vocoders in a preference list that will be included with the same 
preference order in SDP message. 

 

This defines the encoding rate for G723 vocoder. Default setting is 6.3kbps. 

This sets the iLBC size in 20ms or 30ms 

This defines payload type for iLBC. Default value is 97. The valid range is between 96 
and 127. 

Defines payload type for G726-16.  Default value is 98.  Range is from 96 to 127. 

Defines payload type for G726-24.  Default value is 99.  Range is from 96 to 127. 

Defines payload type for G726-40.  Default value is 103.  Range is from 96 to 127. 

Defines payload type for G729E.  Default value is 102.  Range is from 96 to 127 

Default is “No.”  VAD allows detecting the absence of audio and conserves bandwidth
