Chapter 3: Configuration
Second Example: E&M Line
In the E&M Line configuration, the
zaptel.conf
is set for the card to take
timing from the telco on E&M with wink while
zapata.conf
mirrors the
configuration. However, Feat_D is a type of E&M with wink that accepts
DID, but there are many E&M options; E&M_W, E&M, Feat_B, etc.
/etc/zaptel.conf:
span=1,1,o,esf,b8zs
e&m=1-24
/etc/asterisk/zapata.conf:
group=1
context=incoming
signalling=feat_d
channel=1-24
Third Example: PRI
By setting the card to take timing in
zaptel.conf
, you acquire 23 b
channels and voice channels, with channel 24 as the data transport. For
Asterisk, define PRI_CPE so it is the client side. Define the switch type
you are connecting to as
national
. There are several options for the switch
type including 5ESS, 4ESS, and NI1. You will then have 23 voice
channels for Asterisk.
