SIP Stack with SIP Proxy - (VOIP)

SIP Overview

SIP is an application-layer control protocol that can establish, modify, and terminate multimedia sessions (conferences) such as Internet telephony calls. SIP can also invite participants to already existing sessions, such as multicast conferences. Normally SIP uses UDP and TCP port 5060 and TCP 5061 for SSL communication. SIP protocol is very similar to HTTP, so if you have some knowledge about HTTP, then it is easy to learn SIP. SIP doesn't transfer session data like audio, video. RTP(real time protocol) is used for that, SIP just helps to open RTP streams.

SIP Message Example

INVITE sip:john@domain.com SIP/2.0
From: <sip:doe@domain.com>;tag=2084442460
To: <sip:john@1domain.com>
Via: SIP/2.0/UDP domain.com:5060;branch=z9hG4bK2df7b9194cd51e25
Call-ID: john@domain.com-4524j
CSeq: 1 INVITE
Contact: <sip:doe@domain.com:5060>
Content-Length: 226
Content-Type: application/sdp

<session description data, like RTP description>

SIP Server Types

stateless	SIP server doesn't store any transaction info.
statefull	SIP server creates and holds SIP commands transaction state.
registrar/location	Allows users to register their locations and later to use that info to forward calls to registered contact.
B2BUA	SIP server is like statefull + holds active calls state.(This is needed if call billing or full control of call is needed)
presence	Provides user availability services, like if user is online,offline, ... .
...	There are some more, but not so important ones.

Basic SIP Commands

INVITE - Initiates a session. This method includes information about the calling and called users and the type of media that is to be exchanged.
ACK - Sent by the client who sends the INVITE. ACK is sent to confirm that the session is established. Media can then be exchanged.
BYE - Terminates a session. This method can be sent by either user.
CANCEL - Terminates a pending request, such as an outstanding INVITE. After a session is established, a BYE method needs to be used to terminate the session.
OPTIONS - Queries the capabilities of the server or other devices. It can be used to check media capabilities before issuing an INVITE.
REGISTER - Used by a client to login and register its address with a SIP registrar server.

Ok, some ABC done, there are many documents on the internet, so it is not a good idea to rewrite these there.

If want more advanced information, then see:

RFC 3261 (defines SIPv2)

SIP Proxy Demo Overview

This SIP proxy example just implements fully functional simple stateless, statefull, b2bua proxy. You can use hardware SIP phones or soft phones to play with this proxy.This is an advanced example, code is well commented, so beginners don't hate me because no more text here. Just read RFC 3216, see information links I noted earlier. After you go through those, if you then look at the code, it is all nicer then.

Some free available softphones are:

Version:
    11.06.2007
        *) Added B2BUA support.
    07.04.2007 
        *) Many bug fixes. 
        *) SIP -> PSTN and PSTN -> SIP gateway support. 
        *) Non-SIP URI gateway support.

thanks Ivar. would you consider moving your code base to Codeplex or Sourceforge? great Code. especially on SIP. Thanks! You are the ONE.

Hi,
I downloaded code last month and I quickly adapted it to use in my ASP.NET web server,
and it immediately works without problems!

Then I started "play" with code and I found it incredibly valuable and complete,
if you are patient, in this pack you can find a solid base for all your communication needs!

I'm a "normal" developer, to tell I use c# as straight as possible, so initially I found all very complex,
but now I must admit it improved a lot my knowledge and programming skills!

Thanks Ivar Big Grin

How to run both SIP Proxy and a client in the same computer?

First I run the proxy in my computer, then run X-Lite client. But the client can't register in the proxy.

Its not reccomened t run on localhost(127.0.0.1). Also you must ensure that firewall programs wont block UDP traffic.

Thank your reply, Ivar.

I close window's firewall and antivirus software, but it doesn't work.

After I replace localhost(127.0.0.1) with actual IP(192.168.1.112), error occurs in X-lite:
Registration error 407 - Proxy Authentication required. Authentication failed.

Hello,

We are really greatfull for this stack and demo. but we want to understand how demo works. we have 3 years SIP experience as engineer. so we are aware about the registration authantication bla bla issues. i have many times managed to register clients to proxy servers.

now we want to use your stack but we are unable to make the code up and runnning. when we try it after registration packet has arrived we got this error:

Hi, I am trying to make it work at my laptop, single computer. My laptop doesn't belong to any domain, do I have to make it in a domain? Thanks, Linda

Make a dumb domain name in proxy: like "test.com". Aslo fill it in X-Lite.

Thanks Ivar, the domain name problen is solved just using your suggestion. Another problem is the authentification always got error.I did some debugging, I found the response couldn't match the CalculateResponse in the auth.httpdigest.authenticate method. I am guessing the response is from client, and the calculateresponse is calculated by proxy, and I am using x-lite. Do you have any idea about this? Or you may know somebody else have solved this problem.

Anyway, if I return true in the auth.httpdigest.authenticate method, it is working now. Just want to know how the authentification part working. Thanks for your replay agian.
