Hello Dears,

Hope this finds you well.
I am really new in developing.
And i really want to create my own sip web phone client.
Could you please be so kind to advise how to start that? What language is the best and easiest to achieve this, and if there any open source project for sample?

Thank you very much for your assistance and best regards,

OpenH323[^] and Opal[^] are both free, open source and written in C/C++

Iirc, Opal is based off OpenH323 but has a better feature support.

There is a few samples on how to use these included in the source code download, but there is also Ekiga[^] for Linux and MyPhone[^] for Windows which both implement most features available in the libraries.

You will need to get a few other open source libraries and tool to compile them however.
It is all explained in the readme/help files included with the source code
There is a great application which i kind of what you where describing.
It includes development kits for C#/.NET developers.

If it wasn't, still this can give you a good start.
Good luck!
