What are the Asterisk settings to set up our paging speakers?

For both IP Speaker and the Loudspeaker Amplifier, the settings are contained in the sip_additional.conf file in Asterisk. This file should read as follows in which "100" represents the username of our speaker and the password (secret) is ext100:

[100]
username=100
type=friend
secret=ext100
record_out=Adhoc
record_in=Adhoc
qualify=no
port=5060
nat=never
mailbox=100@device
host=dynamic
dtmfmode=rfc2833
context=from-internal
canreinvite=no
callerid=100 <100>
