·Over Lap 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 supplementary services (such as caller
name from CPE over facility).
·NSF
Used with AT&T PRIs. If outbound calls are being rejected due to "Mandatory information
element missing" and the missing IE is 0x20, then you need this setting.
·Echo Cancellation
Disable or enable echo cancellation; it is recommended not to turn this off.
·Hide Caller ID
If you want others to see your CID, please disable this option.
·Codec
You can choose alaw or ulaw.
