Most implementations require this setting to be configured to 1.
Min. Delay before Dial
PSTN 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.
Round Robin and/or
Flexible
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.
Prefix to specify Port
(1 stage dialing method) 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.
Dial Plan The Dial Plan feature implemented is applicable for VOIP to PSTN calls only. You
may configure a dial plan based on the following grammar:
