How to do git clone of kamailio source code with minor version.

I could only do git checkout of 5.3 version and it is automatically taking latest stable version. I don't need in this way. I need to do git clone of exact version of kamailio source code .

Example - if I need 5.3.6 version.. exact version source code has to be git checked out from kamailio website.

How to do that .. kindly let me know..

Thanks,

Pavithra
