VoIP

Interconnecting carrier SIP trunks and enterprise IPBXs looks simple on paper. In practice, it is one of the most expensive friction points in a VoIP infrastructure: you have to secure the IPBX exposed to the Internet, juggle several operators in parallel, fail over when one goes down, normalise routing — all without blowing the budget on a closed, opaque proprietary SBC.

PK-SBC is an open source answer to that problem. A Session Border Controller built on Kamailio, RTP Engine, Redis and PostgreSQL, designed along the KISS principle — Keep It Simple, Stupid — and battle-tested in production since 2012.

With the standard Makefile configuration delivered form git, you can’t compile cdr_pg_csv. You need top edit theMakefile file of cdr_pg_csv module. The file si located here : src/mod/event_handlers/mod_cdr_pg_csv/Makefile . Copy and past the following code :

UNAME := $(shell uname -s)
ifeq ($(UNAME),SunOS)
ISA64 := $(shell isainfo -n)
LOCAL_CFLAGS=-I/usr/include/postgresql
ifneq (,$(findstring m64,$(CFLAGS)))
LOCAL_LDFLAGS=-L/usr/pgsql-9.1/lib/$(ISA64) -R/usr/pgsql-9.1/lib/$(ISA64) -lpq -static
else
LOCAL_LDFLAGS=-L/usr/pgsql-9.1/lib -R/usr/pgsql-9.1/lib -lpq -static
endif
else
LOCAL_CFLAGS=-I/usr/include/postgresql
LOCAL_LDFLAGS=-L/usr/pgsql-9.1/lib -lpq -static
endif
include ../../../../build/modmake.rules

Now, we are ready for make, so do :

This is my first howto in english. As I will release in some days, my project name pyfreebilling (wholesale voip platefom based on Freeswitch, PostgeSQL and Django), i write the first installation step : howto compile and install freeswitch / odbc and postgresql on debian wheezy.

Prerequisites#

You need to install these packages :

apt-get install git-core build-essential autoconf automake libtool libncurses5 libncurses5-dev gawk libjpeg-dev zlib1g-dev pkg-config libssl-dev libpq-dev unixodbc-dev odbc-postgresql postgresql postgresql-client

Configuration#

You download freeswitch using git :
