An MSRP relay is not something that you install and automagically will solve the NAT problems. It has to be used by the endpoints themselves. You'll need to configure your endpoints to use an incoming relay and then you'll see it in the a=path SDP attribute.
Relays need credentials but MSRPRelay uses the credentials from the OpenSIPS subscriber table, so you can specify the same credentials of your SIP account.
