Defining our friends and peers

after setting up our extensions, we need users
SIP phones login to the server using name/password
define these at the end of sip.conf
[jeremy]
type=friend
password=jeremy
context=linux3
host=dynamic
nat=yes
password is unencrypted in this file
nat=yes tells asterisk to ignore address info in the SIP headers, in an attempt to work around NAT
context is where the extension is defined (we already did that)
'friend is matched on username for incoming calls, where peeris only matched on IP
Short answer: always use friend
