Ruwan's techno Blog: SIP

yup , I set up a SIP server (SIP proxy) to test VoIP with our IP DSLAM ... no problem so far , VoIP use very little band width. In the beginning I thought it will be very difficult to set up a SIP server , but it was much easier than I expected and the software are available freely from many vendors. Here I will explain how to use :

SIP server : http://www.brekeke.com/download/download_sip_2_0.php ( SIP server 2.0)
SIP client : http://www.counterpath.com/index.php?menu=Products&smenu=xlite (X-lite 3.0)

first : you need three PCs ( or two PCs also is oki ) and a Small Hub to make a small network

*** may be u can use VMware to run Three OS in the same PC so you do not need a network

Step - 1

install the SIP server in Server- Windows XP is the best for this ( get Academic licence - the process is bit long but it works and its free ) ...

Install the SIP server : to an easy and trouble free installation ,

1) make you IP address fixed ( Manually assigned - NO DHCP) - if the IP address is "assigned by DHCP" the server will refuse to start !!
2) MAke sure that you can acess internet through the same IP address.

*** even if u cannot access internet through the same IP you can get this working but ... kind of .... can cause u trouble . . . just follow the instructions on http://www.brekeke.com/products/products_sip_quickstart.php

username : sa
password : sa

add two user account :

* better to user numbers as user accounts - eg : 101 , but you can use names as well , eg : "ruwan" ...

SIP server uses the TCP port 5060 , make suer that network you are in allows this port !!! ( if this is a local environmant and NO filer wall you do not have to worry abt these stuff )

Add the user info :

click "add" - and thats it !!! and another user the same way , may be as user name "104" so that you have two account for VoIP phones , 103 and 104 ...you can call from 103 to 104 abd vice versa ...
