#PROXY1_DOMAIN = 10.0.0.138
#PROXY1_DOMAIN = axlx.engr.local
#-----------------------------------------------------------------------------------------------#
# PROXYn_MAIL_SUBSCR is who we should subscribe to for mail center notifications
# This is needed only if the user is not subscribed automatically at registration.
# It is almost never required in current versions of Asterisk to specify this.
# If you are using Asterisk (non-business edition) before v1.2, this is necessary.
# This example is actually specific for a line number:3001
#PROXY1_MAIL_SUBSCR = sip:3001@vmail.asterisk.com
#-----------------------------------------------------------------------------------------------#
# PROXYn_MAIL_ACCESS is the main voicemail dial number
# Examples:
#PROXY1_MAIL_ACCESS = 7999
# PROXY1_MAIL_ACCESS = sip:7999@10.0.0.138
# PROXY1_MAIL_ACCESS = 7999@10.0.0.138
# PROXY1_MAIL_ACCESS = 7999

#PROXYn_KEYPRESS_2833 controls generation of in-stream RFC2833 formatted key
# press events. Normally you want this to be disabled for Asterisk but it depends
# on your configuration and what you want to be able to do.
# The default is disable
#PROXY1_KEYPRESS_2833 = disable
#-----------------------------------------------------------------------------------------------#
#PROXYn_KEYPRESS_INFO controls generation of SIP INFO requests to the SIP server
# for keypress events.
# The default is enable
#PROXY1_KEYPRESS_INFO = enable
#-----------------------------------------------------------------------------------------------#
# PROXYn_HOLD_IP0 controls setting of media stream IP destination to 0.0.0.0 when
# a call is put on hold.
# PROXYn_HOLD_IP0 is not required for current versions of Asterisk.
# For older PBXs that require this, set this to enable
# Try toggling this value if you are having problems with hold
#PROXYn_HOLD_IP0 = enable
#-----------------------------------------------------------------------------------------------#
# PROXYn_PRACK enables ACK'd provisional responses to INVITE requests.
# mechanism will be used if this switch is enabled and the Proxy server specifies

# Asterisk, but is to be supported on subsequent versions.

# PROXYn_KEEPALIVE_SECS specifies that the phone should send Keep Alives to the
