"/dev/i4b" supports alerting OK, but "/dev/i4btelXXX" doesn't. And if you want
to get sound-data from a call, one has to do something similar to what
"isdnphone" does, right?
And then comes the problem "/dev/i4btelXXX" can only work as an answering
machine or dial out. There is no "ringing" signal from "/dev/i4bteldXXX" so
that "isdnphone" can decide whether to accept a call or not, and not just
If one does it properly multiple configurations (cep's) in isdnd should be
allowed to compete for a call. Then it should be possible to set up an
answering machine in addition to "isdnphone".
So it would have been nice if you could have had a look at my code to see how
I implemented it, so that we don't end up incompatible.
