The format of zapata.conf (up until 1.4) required that workaround. When
the configuration is generated, it is generated for each channel
separately. If I set the context to, say, "from-internal" for this
channel, I cannot assume it won't be something else on another one.

One method to combat this is to always set all the "options" for all
channels. Even options I don't need for this channel: I might use them
on another one.

Or even worse: what happens if someone #include-s some arbitrary zaptel
configuration in zapata.conf after zapata-channels.conf (as is in, e.g.,
trixbox).

So I chose to try to "reset" the options. I can't just "save" the
configuration before configuring the channel and "restore" it later.
So I must revert to resetting to defualt values.

The proper fix: in Asterisk 1.6 zapata.conf supports separate contenxts
for channels. This allows me to safely apply some configurations just
for a single channel (or a group of them).
