[SR-Users] UAC Register Asterisk

[Marrold]

Why not just authenticate on Kamailio in that case?

Also, be aware that the Authorization Username ($au) is included in SIP
digest authentication. $au and $fu aren't necessarily the same,  but on
most end points the default is to use the same value for both. If you
manipulate $fu or $au it may cause auth issues.
