Chapter 3: Configuration

Second Example: E&M Line

In the E&M Line configuration, the

system.conf

is set for the card to

take timing from the telco on E&M with wink while

chan_dahdi.conf

mirrors the configuration. Feat_D is a type of E&M with wink that
accepts DID, but there are many other E&M options; E&M_W, E&M,
Feat_B, etc.

/etc/dahdi/system.conf:

loadzone = us

defaultzone = us

span = 1,1,0,esf,b8zs

e&m = 1-24

echocanceller = mg2,1-24

/etc/asterisk/chan_dahdi.conf:

group = 1

echocancel = yes

context = incoming

signalling = feat_d

channel = 1-24
