Firmware Version 1.4.1.5
Most implementations require this setting to be configured to 1.
Default is 500ms. This needs to be equal to or greater than the Current Disconnect
threshold setting. Once the threshold is reached the gateway can dial out. This
parameter should only be used if there are PSTN line detection issues.
Default is rr:1-8;
The syntax is pretty straight-forward here. The rr stands for Round Robin and the
numbers stand for the ports that belong to that round robin group.
For example:
rr:1-8; -> Round robin within the first 8 ports i.e. outgoing calls will be forwarded to the
next available port within the group of ports 1 to 8.
rr:1,3-6,8;rr:2,7; -> Round robin within port 1,3,4,5,6 and 8; Second round robin group
within ports 2 and 7 i.e. outgoing calls to ports 1,3,4,5,6 and 8 will be forwarded to the
next available port within this group ONLY. Outgoing calls to port 2 and 7 will be
forwarded to the next available port between ports 2 and 7 ONLY.
** In order to terminate a call on FXO port 2 or 7 you will need to change its Local SIP
Listen port accordingly.
Default is 99.
Syntax to USE this feature: prefix# (that is 99) + ch# (could be anything from 1 to 8) +
dialing# will result in this call forwarded to FXO port (ch#) immediately.
The Dial Plan feature implemented is applicable for VOIP to PSTN calls only. You
may configure a dial plan based on the following grammar:
1. Accept Digits: 1,2,3,4,5,6,7,8,9,0,*,#,A,a,B,b,C,c,D,d
2. Grammar:
x - any digit from 0-9;
xx+ - at least 2 digit number;
xx. - at least 2 digit number;
^ - exclude;
[3-5] - any digit of 3, 4, or 5;
[147] - any digit 1, 4, or 7;
<2=011> - replace digit 2 with 011 when dialing
WARNING - illegal input will fall back to default
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
{ [x#]+ | [x*]+ } - Allow any length of number with leading * or
Example 4:
# in number to dial.
Default: PSTN Outgoing - {x+}
Note: If you do not plan to use this feature set to default {x+}
Default 600ms. This value can accept any value in the 100-2000ms range.
Default Yes, No means to use DTMF parameter settings according to DTMF Digit
Length, DTMF Digit Volume and DTMF Dial Pause.
Default value is 100ms. Please note that the value will be multiplied by 10ms
Default value is -11dB.
