[SR-Users] How to change MSRP from sip address?

This From header is in the MSRP message itself, it is not in the INVITE
opening the MSRP session.

I guess this is an extension of your MSRP client or maybe an addition
done later to the core MSRP RFC, because there only From-Path is
defined, iirc.

There is no function offered by the msrp module in kamailio.cfg to
change that header, so it will require to write some c code to implement
such functionality.

Cheers,
Daniel
