This<br>
is all part of my retirement project - a brain dump.<br>
They cover some basics of SIP in depth, referencing how solutions are built<br>
using OpenSIPS.<br>
There are four based loosely on the theme of "header fixing" - this<br>
introductory one has links to the other three:<br>

<br>

route headers:<br>

<br>
I'd be happy to receive feedback/criticism/comment/suggestions for<br>
improvements.<br>
<br>
I'm also just finishing one that talks about issues and snags encountered<br>
when setting up a Teams SBC. Details to follow.<br>
