PRI Options
Switch type
Sets the type of PRI switch being used. Default: national. Acceptable values are:
* national: National ISDN type2 (common in the US)
* ni1: National ISDN type 1
* dms100: Nortel DMS100
* 4ess: AT&T 4ESS
* 5ess: Lucent 5ESS
* euroisdn: EuroISDN
* qsig: Found in source (little help here?!)
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. Valid options are:
unknown, local, private, national, and international. This option can almost always be left unchanged from the
default. Default: national.
PRI Local Dial Plan
Local PRI dial plans, Default=local
Over lapdial
Whether Asterisk can dial this switch using overlap digits. Default: no
PRI Indication
Tells how Asterisk should indicate Busy() and Congestion() to the switch/user. Default: inband. Accepted
values are:
