Zaptel does not use indications.conf, because that is an Asterisk
configuration file :-) But you are correct, chan_zap does not use
indications.conf, it allows Zaptel to generate indication tones instead,
and Zaptel uses the tonezone data that is compiled into it.

Based on my quick reading of zt_callwait in chan_zap.c, it appears that
the frequency and duration values of the callwaiting beep tone are
hardcoded in the source of chan_zap.
