# 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. The PRACK
# mechanism will be used if this switch is enabled and the Proxy server specifies
# support for the PRACK mechanism. PRACK is NOT SUPPORTED in current versions of
# Asterisk, but is to be supported on subsequent versions. PRACK should not be
# required on local area networks.
#PROXY1_PRACK = disable
#---------------------------------------------------------------------------------------------#
# PROXYn_KEEPALIVE_SECS specifies that the phone should send Keep Alives to the
# PROXYn server. It can be set to 0 or anywhere from 10 to 3600 seconds.
# The default value (which is applied if no parameter is supplied in this file) is
# 0 which means the phone will not send keep_alives to PROXYn.
#
# If the phone failes to get a keepalive response within the SIP 32 second
# timeout, the keepalives are terminated for that PROXY until the next successful
# registration to the PROXY.
#
# This parameter is REQUIRED on Asterisk Business Edition with the Polycom 8002
# phone but not with the Polycom 8020/8030 phones. This is because Linux, the
# OS running Asterisk, has a ARP Cache flushing mechanism. This feature serves
# to refresh the ARP Cache for the 8002 phones. For 8020 and 8030 phones, the
# ARP Cache is refreshed by the SVP server. 8020/8030 phones do not know how to
# parse this parameter.
#
# The value of this parameter for 8002 phones should be just less than the
# minimum ARP Cache flushing time on the Linux box running Asterisk. For Redhat
# this minimum flushing time is 15 seconds, so the parameter needs to be set for
# 14 seconds or less. For other Linux Distributions, you may have to determine
# what this minimum value is, however 14 seconds should work fine.
#
# The lower this setting, the more the impact on the 8002's standby battery life.
#(8002 phones running version 130.003 and earlier code ignore this parameter if
# present)
#(8020/8030 phones ignore this parameter if present no matter the SW version)
#PROXY1_KEEPALIVE_SECS=14
#---------------------------------------------------------------------------------------------#
# PROXYn_REREG_SECS specifies the the re-registration interval for a PROXY. This
# is the requested expiration interval sent in the REGISTER request message. It can
# be set to anything between 35 and 3600 seconds.
# The default value (which is applied if no parameter is supplied in this file) is
# 3600 which means the phone will attempt to register every 3580 seconds, if the
# server's response interval doesn't take precedence (see below).
#
# If the server has a lower maximum setting or a higher minimum setting that
# this value then the server's response will take precedence and this parameter
# will be ignored.
#
# The phone will always attempt to re-register with the PROXY 20 seconds prior to
# the expiration interval. Thus, if this parameter is set to 35 seconds, and the
# server's response interval doesn't take precedence, then the phone will attempt
# to re-register every 15 seconds.
