I have written several articles recently that people might find useful. This is all part of my retirement project - a brain dump. They cover some basics of SIP in depth, referencing how solutions are built using OpenSIPS. There are four based loosely on the theme of "header fixing" - this introductory one has links to the other three: https://kb.smartvox.co.uk/opensips/nat-contact-and-via-fixing-in-sip-part-1/
and there is one that examines loose routing plus contact, record-route and route headers: https://kb.smartvox.co.uk/opensips/contact-and-record-route-headers-explaine d/ I'd be happy to receive feedback/criticism/comment/suggestions for improvements. I'm also just finishing one that talks about issues and snags encountered when setting up a Teams SBC. Details to follow.
