qsig: Minimalistic protocol to build a "network" with two or more PBX of different
vendors!
·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().
·Facility Enable
To enable transmission of facility-based ISDN supplementary services (such as
caller name from CPE over facility).
