BRI Trunks
Basic Rate Interface (BRI, 2B+D, 2B1D) is an Integrated Services Digital Network
(ISDN) configuration intended primarily for use in subscriber lines similar to those that
have long been used for plain old telephone service. The BRI configuration provides 2
bearer channels (B channels) at 64 kbit/s each and 1 data channel (D channel) at 16
kbit/s. The B channels are used for voice or user data, and the D channel is used for
any combination of data, control/signalling, and X.25 packet networking.
To extend BRI trunks on MyPBX, please install B2 module on MyPBX, and connect
the BRI port to the BRI provider with a RJ45-RJ11 cable.

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.
