21 ; We can optionally override the auto detection. This is necessary
22 ; particularly if asterisk does not know about our kind of modem.
27 ; We can strip a given number of digits on outgoing dialing, so, for example
28 ; you can have it dial "8871042" when given "98871042".
37 ; Mode selection. "Immediate" means that as soon as you dial, you're connected
38 ; and the line is considered up. "Ring" means we wait until the ring cadence
39 ; occurs at least once. "Answer" means we wait until the other end picks up.
45 ; List all devices we can use.

55 ; More complex ISDN example
57 ; A single device which listens to 3 MSNs
58 ; the wildcard '*' can be used when all MSN's should be accepted.

76 ; none: Don't detect inband DTMF
