Overlap Dial
Define whether MyPBX can dial this switch using overlap digits
or not. 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.
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 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().
Enable Facility
To
enable
transmission
of
facility-based
ISDN
supplementaryservices (such as caller name from CPE over
facility).
