Users call into our Asterisk voice server through a Zaptel PCI
interface from regular phones, usually from a PBX (virtually all of
them ISDN-based).

The only files I modified are zaptel.conf, zapata.conf, and
extensions.conf, which don't have anything DTMF-related, so Asterisk
uses the default options.

Thanks.
