;===============
; More complex ISDN example
;
; A single device which listens to 3 MSNs
; the wildcard '*' can be used when all MSN's should be accepted.
; (The incoming number can be used to go directly into the extension
; with the matching number. I.e. if MSN 33 is called, (context,33)
; will tried first, than (context,s) and finally (default,s).

; If set, only these numbers are allowed to be set as A number
; when making an outbound call. callerid is used to set A
; number.

; Set DTMF-detection/generation mode to:
;  asterisk: Let Asterisk do inband detection (default)
;  i4l:      Use the inband detection made by ISDN4Linux
;  none:     Don't detect inband DTMF
;  both:     Transmit using both in-band and out of band (generation only)
;
; You may specify either one mode, or the detection/generation mode
; individually separated by a '/'.

; two other devices, which are in group '1' and are used when an
