; 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).

; two other devices, which are in group '1' and are used when an
; outgoing dial used: exten => s,1,Dial,Modem/g1:1234|60|r
