autodomain
Set this option to yes to have Asterisk add the local hostname and local IP addresses
to the domain list:
autodomain=yes|no
bindaddr and bindport
These optional parameters allow you to control the IP interface and port on which
you wish to accept SIP connections. If omitted, the port will be set to 5060, and all
IP addresses in your Asterisk system will accept incoming SIP connections. If mul-
tiple bind addresses are configured, only those interfaces will listen for connections.
The address 0.0.0.0 tells Asterisk to listen on all interfaces:
bindaddr=0.0.0.0
bindport=5060
buggymwi
This setting allows Asterisk to send a message-waiting indication to certain Cisco
SIP phones with firmware that doesn’t fully support the message-waiting Internet
RFC. Enable this option to avoid getting error messages when sending MWI mes-
sages on phones with this bug:

buggymwi=no|yes
callevents
Set this to yes when you want SIP to generate Manager events. This will be im-
portant if you have external programs that use the Asterisk Manager interface, such
as the Flash Operator Panel:
callevents=yes
checkmwi
This option specifies the default amount of time, in seconds, between mailbox
checks for peers:

checkmwi=30
compactheaders
You can set compactheaders to yes or no. If it’s set to yes, the SIP headers will use
a compact format, which may be required if the size of the SIP header is larger than
the maximum transmission unit (MTU) of your IP headers, causing the IP packet
to be fragmented. Do not use this option unless you know what you are doing:
compactheaders=yes|no
defaultexpiry
This sets the default SIP registration expiration time, in seconds, for incoming and
outgoing registrations. A client will normally define this value when it initially
registers, so the default value you set here will be used only if the client does not
specify a timeout when it registers. If you are registering to another user agent server
(UAS), this is the registration timeout that it will send to the far end:
