Building A Phone System Capable of scaling up in every direction

Load Balancing 2 a2billing/freepbx Servers and 2 BlueBox Server while terminating local calls itself. It also handles nated agents And soon to handle presence.

In these Configuiration i have a total of 6 servers.

OpenSips Server
Database Server
2 * A2billing Servers (Working as billing/ Authentication Servers)
2 * BlueBox Servers (Working as Media Servers)

All Servers Connect to the same database And we have created an a2billing View insde the Opensips database which mirrors a2billing cc_sip_buddies table.

With this set all asterisk and bluebox servers can remain on a private ip address since opensips is the proxy and and has public interface and private ip address (I used 2 nics, but a 1 to 1 Nat may work)

FYI (I use Untangle as my Firewall.. great firewall if you have the right hardware. But with this firewall i had to disable Sip Helper. Sip Helper conflicts with nat transversal technics used. After disabling i had to restart the untangle server.)

This Config Is Still Being Worked on. The following is still a work in progress. (will take help from others)

Presence Server isnt configured
Multi-domain is supported yet.. ( I added bluebox servers to impliment multi-tenet ) although partitioning context should work, clients will not yet be able to have to same extenstion as that another client has until i get this working
Checking voicmail without typing password

All Phones Connects to the proxy.. My services include residential and Commercial phone service along with sip trunking. later ill include IM Support so that instant messangers will work and be able to make calls as well.

Opensips registers users that are in a2billing.. It then reads all calls, in this config extenstions are 4 digits long it will terminate all calls 2XXX Itself and send other calls too the loadbalancer Module.

The load Balancer will read all calls and send Voicemails calls to to the server is the database for voicemail Calls, And it will send all calls for confrences to the server designated for confrences and do the same thing for PSTN Calls

Installing Opensips

yum install gcc bison flex zlib-devel openssl-devel openssl-devel libxml-devel mysql-devel perl-DBI libcurl-devel

make include_modules="db_mysql Load-Balancer presence MEDIAPROXY PRESENCE_MWI PRESENCE_XML" prefix="/" all
make include_modules="db_mysql Load-Balancer presence MEDIAPROXY PRESENCE_MWI PRESENCE_XML" prefix="/" install

Edit config for database

#nano /etc/opensips/opensips.cfg

create database
/sbin/opensipsdbctl create

In my setup opensips connects to a2billing using a MySQL VIEW

CREATE VIEW a2billing AS select `mya2billing`.`cc_sip_buddies`.`id` AS `id`,`mya2billing`.`cc_sip_buddies`.`username` AS `username`,`mya2billing`.`cc_sip_buddies`.`outboundproxy` AS `domain`,`mya2billing`.`cc_sip_buddies`.`secret` AS `password`,_latin1'' AS `ha1`,_latin1'' AS `ha2`,_latin1'' AS `rpid` from `mya2billing`.`cc_sip_buddies`

I suppose if you want to use freepbx/trixbox you may can create this view

CREATE VIEW `opensips`.`subscriber` AS select

  `asterisk`.`sip`.`id` AS `id`,
  `asterisk`.`sip`.`id` AS `username`,
  _latin1'emunited' AS `domain`,
  `asterisk`.`sip`.`data` AS `password`,
  _latin1'' AS `ha1`,
  _latin1'' AS `ha2`,
  _latin1'' AS `rpid`

from `asterisk`.`sip` where keyword='secret';

When dialing out through a2billing to a bluebox Server number try's to terminate as NXXNX/XXXXXX,60,HRrL(5400000

I have spent hours trying to figure this out.. but i notice it only didnt work when i connect to a bluebox PBX provider.. which is also me...

When connecting to my asterisk box there's no problem.. maybe asterisk deletes everything after the number by default.

Bluebox shows the number being dial as "1678XXXXXXX,60,HRrL(5400000"

Instead of "1678XXXXXXX"

My simple fix is deleting "|60|HRrL(%timeout%:61000:30000)" in a2billing under "Dial Command Params"
