Great addons for Asterisk based Trixbox : Gtalk Skype KDE VNC HUD

* Set up Linux GUI in Trixbox ( CentOS )

People having less experience with Linux can use its GUI for Trixbox basic understanding, and if you have hands on shell expertise you can skip the GUI setup.

Procedure:

Install Basic Window System and then KDE

# yum groupinstall "X Window System" "KDE (K Desktop Environment)"

To connect to the Linux server GUI install vnc server

# yum list vnc*
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
.
.
Installed Packages
vnc-server.x86_64 4.1.2-14.el5_5.4 installed
Available Packages
vnc.x86_64 4.1.2-14.el5_5.4 updates

If you dont have it installed, you can install vncserver by selecting appropriate package from above list

# yum install vnc-server.x86_64

Once its installed you can start vnc server by following, it may ask you for a password to connect to vnc

# vncserver

[root@cent52 ~]# vncserver

New 'cent52:1 (root)' desktop is cent52:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/cent52.server.com:1.log

[root@cent52 ~]#

NOTE: KDE Wont start itself, to start it at the time of VNC connection make appropriate changes in file /root/.vnc/xstartup

#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
startkde &
kdesktop &

Now you must be able to connect to your server via vnc
You can use tightvnc as vnc viewer.

So now our initial step is done hence we can move ahead.

* Set up Hud Lite Server in Trixbox.

With HUDLite you can see the status of all of the extensions on your phone system.

HUD Lite server basically runs with an asterisk manager and an IRC client. So you’re asterisk must be running as basic.

[trixbox ~]# ps aux | grep "asterisk"
root 20994 0.0 0.0 4504 548 ? S Apr03 0:00 /bin/sh /usr/sbin/safe_asterisk -U asterisk -G asterisk

asterisk 23067 0.0 0.6 33392 11520 ? S 04:02 0:00 /usr/sbin/httpd
asterisk 23068 0.0 0.5 29360 9228 ? S 04:02 0:00 /usr/sbin/httpd
asterisk 23069 0.0 0.3 27976 5740 ? S 04:02 0:00 /usr/sbin/httpd
root 32553 0.0 0.0 3936 700 pts/0 S+ 06:26 0:00 grep asterisk
[trixbox ~]#

Go to web Trixbox admin panel of you’re server via web. ( http://<ip> )
Go to packages and click on install for the following packages

"hudlite-server"
"tbm-hudadmin"

and Install them as both packages are necessary

Now this is a tricky part for HUD

[trixbox ~]# mkdir /etc/asterisk/hud
[trixbox ~]# chown asterisk.asterisk /etc/asterisk/hud
[trixbox ~]# service hudlite-server start
[trixbox ~]# Starting hudlite-server: [ OK ]

You can check now that HUD Lite server and ircd server is running

[trixbox ~]# netstat -a | grep 6600
tcp 0 0 *:6600 *:* LISTEN
tcp 0 0 trixbox:43466 trixbox:6600 ESTABLISHED
tcp 0 0 trixbox:6600 trixbox:43466 ESTABLISHED

[trixbox ~]# ps aux | grep "ircd"
ircd 21415 0.0 0.6 15172 10956 ? Ss Apr03 0:00 ircd
root 32599 0.0 0.0 3932 688 pts/0 S+ 06:33 0:00 grep ircd
[trixbox ~]#

You can check service stability by doing

[trixbox ~]# /etc/init.d/ircd restart
[trixbox ~]# /etc/init.d/hudlite-server restart

Now you can check your server status in web GUI, It must show HUD Server Running

From WEB GUI go to PBX -> HUDLite Admin
The extensions and their passwords are kept here.

Configuring HUD clients.

Start you’re HUD client and go in the connection properties

Put User name as sip1001 if you’re extension is 1001
Put password as given in web GUI for the extension

Put IP of you’re Trixbox server in Server
Password is password
Port no. 6600

And you must be able to connect to server.

Whoooaaaaa one more Trixbox Addon done !!!

* Set up gTalk in Trixbox

Configuring the gtalk account in Trixbox. This can really be your company DID for receiving and making gtalk to gtalk or gtalk to world calling.

Carefully follow given instruction as wrong configuration will only last in hair loss.

Install start up modules

# cd /etc/asterisk/
# yum update
# yum install gcc*
# yum install theo*
# yum install ikse*
# yum install gnutls*
# yum install xmlsec*
# yum install speex*

gtalk's jingle protocol runs over TLS hence we need to add TLS support in our server.

You can verify whether the TLS has been installed properly or not by writing following simple C program

gtalk-tls.c

Code:

#include <stdlib.h>
#include <stdio.h>
#include <iksemel.h>

int main()
{
       printf("Checking server for TLS\n\r");
       if(iks_has_tls())
               printf("Yes !! We have TLS.\n\r");
       else
               printf("Sorry !! I dont find it.\n\r");
       return 0;
}

Compile it and run

gcc -l iksemel -o gtalk-tls gtalk-tls.c

# ./gtalk-tls

Checking server for TLS
Yes !! We have TLS.

Now we will check the config file for gtalk and jabber

# vi /etc/asterisk/gtalk.conf
[general]
context=googlein
allowguest=yes
bindaddr=LANIP ; If you are running on Public IP then
; bindaddr=PUBLICIP
externip=PUBLICIP

;
[guest]
disallow=all
allow=ulaw
context=googlein

[buddy]
username=mybestfriend@gmail.com

disallow=all
allow=ulaw
context=googlein
connection=asterisk

# vi /etc/asterisk/jabber.conf
[general]
debug=yes
autoprune=no
autoregister=yes

[asterisk]
type=client
serverhost=talk.google.com
username=myaccount@gmail.com/Talk
secret=mypassword
port=5222
usetls=yes
usesasl=yes
buddy=mybestfriend@gmail.com
statusmessage=”This is an Asterisk server proudly hosted at eukhost.com”
timeout=10

Now we need to configure gtalk audio conection protocol "Jingle"

# vi /etc/asterisk/jingle.conf
[general]
context=googlein
allowguest=yes
bindaddr=LANIP ; If you are running on Public IP then
; bindaddr=PUBLICIP
externip=PUBLICIP

;
[guest]
disallow=all
allow=ulaw
context=googlein

[buddy]
username=mybestfriend@gmail.com

disallow=all
allow=ulaw
context=googlein
connection=asterisk

You have to add custom context in order to integrate gtalk with asterisk, Trixbox

# vi /etc/asterisk/extension_custom.conf
[googlein]
exten => s,1,NoOp( Call from Gtalk )
exten => s,n,Set(CALLERID(name)=”From Google Talk”)
exten => s,n,Dial(SIP/1001) ; 1001 is the extension where I want to terminate the incoming call on my gtalk id.

[googleout]
exten => 200,1,Dial(gtalk/asterisk/mybestfriend@gmail.com) ; If any extension dials 200 the call will be placed to friend using gtalk.
exten => 300,1,Dial(gtalk/asterisk/anotherfriend@gmail.com)

# vi /etc/asterisk/rtp.conf

[general]
;
; RTP start and RTP end configure start and end addresses
;
rtpstart=10000 ; this is default range
rtpend=20000

rtpstart=1650 ; This is needed by gtalk
rtpend=4560

rtpstart=40000 ; This is the UDP port range from where the audio traffic will go.
rtpend=66000 ; This will also help you in debugging.

Now lets apply everything and get our fingers crossed.

[Trixbox $] # asterisk -r
Trixbox CLI> reload
Trixbox CLI> jabber test

Trixbox CLI> reload
Trixbox CLI> jabber test
User: mybestfriend@gmail.com
Resource: 1A945032
client: *******
version: ANYTHING
Jingle Capable: 1
Priority: 1
Status: 1
Message: Speeding up !!!

The jingle capable:1 shows that both users can talk with each other.

* Set up Skype for SIP in Asterisk

Note: Configuring Skype for SIP will require you to purchase a SIP account from skype.com

Once you get the username and password details from skype.com, configure it as a trunk in your asterisk.

SKYPE Trunk Settings for using Skype over SIP for Asterisk.

Go to your FreePBX Trunks setting

Say "Add SIP Trunk" and fill in following details

Maximum Channels: ; Set this to your purchased maximum number of channels.

Dial Rules: ; Set your appropriate dial rule.

Outgoing Settings
-----------------

Trunk Name : 99999999999999 ; Give some trunk name, e.g your skype id.
PEER Details ; Fill in your PEER details to make outgoing calls using Skype.

username=99999999999999
type=friend
srvlookup=yes
secret=xxxxxxxxxxxxxxx
nat=no ; You will need to set it to yes if your PBX is on private network.
insecure=very
host=sip.skype.com
fromuser=99999999999999
fromdomain=sip.skype.com
disallow=all
context=default
canreinvite=no
allowoverlap=no
allow=ulaw&alaw&g729

Incoming Settings
-----------------

USER Context : ; Give some name here

USER Details: ; Fill in your USER details to receive incoming calls over Skype SIP.

username=99999999999999
secret=xxxxxxxxxxxxxxx
nat=no
host=sip.skype.com

Registration ; This is necessary to get yourself registered at Skype SIP.
-----------

Register String:
99999999999999

xxxxxxxxxxxxxx@sip.skype.com/xxxxxxxxxxxxxxx

Now you should be able to use this skype trunk for outbound dialing

I hope you will surely like these four super-cool add-ons with Trixbox.

Thanks a lot for such a wonderful information regarding Trixbox.

I am new user to asterisk and just installed the KDE GUI on my recent CentOS from your post. KDE is running fine but I want to install Trixbox packages on centos. ( I hope that's possible )

Will ask you if I start pulling my hairs.

Hi,

I have been dreaming Elastix and HUD go hand in hand. Do you have any good documentation on that ?

By following your steps I have been successful with gtalk on elastix but now I'm trying with HUD.

Also there are lot of broken links on internet for this topic.

Thanks.

Hi,

Nice to hear that post helped :)

I have been dreaming Elastix and HUD go hand in hand. Do you have any good documentation on that ?

I have not done it yet but will try to work on elastix and hud.

In the mean time I was working on DAHDI installation with asterisk, its pretty simple though I would like to share it with all the readers,

DAHDI is a driver's name for running TDM cards in asterisk. I used Digium PRI TE121 card for integrating the E1 line.

Important Note: Before inserting the card in the system, please check whether the jumper on the card is at correct line type. For example refer card installation manual for E1 or T1 settings.

You can start your asterisk server and you have to change your country settings.

[trixbox ~]# vi /etc/dahdi/genconf_parameters

lc_country XX

Then let the system generate your server configuration

[trixbox ~]# dahdi_genconf

Now reboot the server and execute following command.

If the card gets correctly configured then you should see the "alarms=OK".

[trixbox ~]# dahdi_scan

[1]
active=yes
alarms=OK
description=Wildcard TE121 Card 0
name=WCT1/0
manufacturer=Digium
devicetype=Wildcard TE121 with VPMADT032
location=PCI Bus 03 Slot 09
basechan=1
totchans=31
irq=169
type=digital-E1
syncsrc=1
lbo=0 db (CSU)/0-133 feet (DSX-1)
coding_opts=HDB3
framing_opts=CCS,CRC4
coding=HDB3
framing=CCS
[trixbox ~]#

Now you can use this DAHDI trunk for your outbound and inbound calling. You will need to set appropriate inbound and outbound routes in FreePBX for DAHDI.

Hope this helps. !!!
