How to use Zap instead of DAHDI
As ZAPTEL is now not used in Asterisk, systems that are still using ZAP channels can be configured to use Dahdi.
Edit /etc/asterisk/asterisk.conf file and add this line:
dahdichanname = no
Adding this entry solves a few issues:
All CLI commands that begin with 'zap' are now available as 'dahdi' commands as well; the 'zap' variants will report that they are deprecated the first time you use each one in an Asterisk instance, but they will otherwise operate just as they did in previous versions
Channel configurations will be read from
/etc/asterisk/zapata.conf
So if you use "dahdichanname = no" - make sure to enter channel configuration in that file.
