[SR-Users] Can the SBC (Kamailio 3.1.x and FreeSWITCH 1.0.6+) do Upper Registration?

[Alex Balashov]

Yes, you can do this either by relaying the registrations + using 
Path, or by using the 'uacreg' table in the 'uac' module, depending on 
just how much you want to relay the registrations upstream 1-for-1.
