· PRI Dial Plan
Sets an option required for some (rare) switches that require a dial plan
parameter to be passed. This option is ignored by most PRI switches. It may be
necessary on a few pieces of hardware. This option can almost always be left
unchanged from the default.
· Reset interval
Set the time in seconds between restart of unused channels. Some PBXs don't
like channel restarts. so set the interval to a very long interval e.g. 100000000
or 'never' to disable *entirely*. If you are in Israel, the following is important:
As Bezeq in Israel doesn't like the B-Channel resets happening on the lines, it is
best to set the reset interval to 'never' when installing a box in Israel. Our past
experience also shows that this parameter may also cause issues on local
switches in the UK and China.
· PRI Local Dial Plan
Sets an option required for some (rare) switches that require a dial plan
parameter to be passed. This option is ignored by most BRI switches. It may be
necessary on a few pieces of hardware. This option can almost always be left
unchanged from the default.
· Over Lap Dial
Define whether MyPBX can dial this switch using overlap digits. If you need
Direct Dial-in (DDI; in German "Durchwahl") you should change this to yes, then
MyPBX will wait after the last digit it receives.
· PRI Indication
Tells how Device should indicate Busy() and Congestion() to the switch/user.
Accepted values are:
inband: Device plays indication tones without answering; not available on all
PRI/BRI subscription lines .
outofband: Device disconnects with busy/congestion information code so the
switch will play the indication tones to the caller. Busy() will now do same as
setting PRI_CAUSE=17 and Hangup().
