[@adithyakr]

Nice one Vishal. Thank you.:-)

[@ArunKonkati]

Dude you are just awesome!! Thanks alot for sharing!! I have a question, When this Invite, trying, ringing and Ok messages will come into picture when registering the sip PHONE? Is that the same as Request and Response or after authorization sip phone will send invite messages? Please clarify my doubt?

[@VishalPatel4487]

Thank you arun. This video explains only registration part. Invite, Trying & ringing & ok comes into the picture when you make call to other party. When you send invite to other party, server 'll send the proxy-authorization header instead of www-authenticate header.

[@ArunKonkati]

Oh great!! thats awesome u cleared my doubt

[@venkaiahgunduboina4416]

Nice video ......@

[@sahild6584]

Excellent, outstanding!!!!!!!!!

[@ashutosh567]

GOOD JOB !!! Very well explained!

[@harshdeepsingh4165]

lovely explaination.

[@anthonyfredrick838]

INFORMATIVE VIDEO.. THANK YOU

[@niteshvashist2151]

Gud work Vishal.. keep It up.. But I have some doubts regarding this first is. 1) why you use only python for calculating response means can we do it in C. If we can then please give some hint and 2) Apart from MD5 is there any other Algorithm to calculate response . if so then let us know.. waiting for your valuable reponse. :)

[@VishalPatel4487]

Thank you Nitesh for your encouraging words. You can calculate the response on any language. Fundamental for SIP is same as HTTP protocol. Every protocol has RFC (Request for Comment) document in which they define how this protocol should work. The current RFC is RFC3261. In that they have define to use digest authentication using MD5. HTTP also uses MD5 for checking authentication.

[@Major7Sharp5]

Very nice explanation, thank you

[@B2B_gyan]

Sorry to interrupt you My friend But one thing you should always remember that a Proxy server will always give 407 Authentication and a Registrar server will give 401 Authentication. In the slide you mentioned Proxy server. PDN

[@VishalPatel4487]

Thank you praveen.Yes, i think, it should be SIP server. SIP server can act as a proxy server also as a register server. Concept wise it is same. If any other difference, please share. It would be helpful to all of us.

[@BandikatlaSaicharan]
