Page 383 - Asterisk™: The Future of Telephony

minexpiry
This sets the minimum amount of time, in seconds, allowed for a registration or
subscription:
maxexpiry=3600
notifymimetype
This takes as its argument a string specifying the MIME type used for the message-
waiting indication (MWI) in the SIP NOTIFY message. The most common setting
for this field is text/plain, although it can be customized if need be:
notifymimetype=text/plain
notifyringing
Specifies whether Asterisk should notify subscriptions on RINGING state:

notifyringing=yes|no
notifyhold
Specifies whether Asterisk should notify subscriptions on HOLD state:
notifyhold=yes|no

pedantic
You can set pedantic to yes or no. Setting it to yes enables slow pedantic checking
for phones that require it, such as the Pingtel, and enables more strict SIP RFC
compliancy. In an effort to improve performance, SIP RFC compliance is not nor-
mally strictly adhered to:

pedantic=yes
realm
This option sets the realm for digest authentication. Set realm to your fully qualified
domain name, which must be globally unique:
realm=mybox.example.com
recordhistory
You can set recordhistory to yes or no to enable or disable SIP history recording
for all channels:
recordhistory=yes|no

registerattempts
Specifies how many times Asterisk will attempt its outbound registrations before
giving up. This setting defaults to 0, which means that Asterisk will retry
indefinitely:
registerattempts=0
registertimeout
Specifies how often Asterisk should attempt to re-register to other devices:
registertimeout=30
