I think it's not. You need to understand how protocols work with each other if you are building a service with them. You don't necessarily need to read tons of specifications, MSRP for example is just 2 RFCs, one for the core protocol and another one for using relays for NAT traversal.

Here are some examples on how the relays are inserted on the SDP: https://tools.ietf.org/html/rfc4976#section-11

We also have different scenario usage diagrams on msrprelay.org.
