# sst_b2b SBC profile

|
|
# This implements a transparent B2BUA with
|
|
# SIP Session Timers known from the sst_b2b app.
|
|
# Also see the description below.
|
|
|
|
# defaults: transparent
|
|
#RURI=$r
|
|
#From=$f
|
|
#To=$t
|
|
|
|
## filters:
|
|
#header_filter=blacklist

#header_list=P-App-Param,P-App-Name

## authentication:
|
|
#enable_auth=yes
|
|
#auth_user=$P(u)
|
|
#auth_pwd=$P(p)

|
## session timer:
|
|
enable_session_timer=yes
|
|
# if session_expires is not configured here,
|
|
# the values from sbc.conf are used, or the
|
|
# default values
|
|
#session_expires=120

#minimum_timer=90

#session_refresh_method=UPDATE_FALLBACK_INVITE

|
#
|
|
#This application can be routed through for achieving
|
|
#two things:
|
|
#
|
|
# 1. Forcing SIP Session Timers, which prevents
|
|
# overbilling for calls where BYE is missing,
|
|
# for example in cases where media (RTP) path
|
|
# does not go through the system, but billing
|
|
# is still done.
|
|
#
|
|
# 2. Topology hiding; this application acts as
|
|
# B2BUA, so on the B leg, no routing info from
|
|
# the A leg can be seen.
|
|
#
|
|
#The incoming INVITE for a newly established call is
|
|
#passed in signaling only B2B mode to the B leg,
|
|
#which tries to send it to the request URI.
|
|
#
|
|
#SIP Session Timers are enabled on both legs. The
|
|
#session refresh method may be configured; UPDATE
|
|
#or INVITE with last established SDP may be used.
