Record-Route and Loose Routing

I have just published a new post on my wiki site which examines how Contact, Record-Route and Route headers are used in what is known as “loose routing”. This is a somewhat fundamental part of understanding how SIP Proxies work and if you don’t get this, then you’ll probably find it very difficult to understand what’s going on in a SIP trace or packet capture. So if you don’t already have this topic under your belt, go and take a look at my latest tutorial article. Just click on this link:

…and, if you find it helpful, please remember to use the Like or Recommended buttons that you’ll find at the end and start of the post.
