[SR-Users] Kamailio second contact header

[Daniel-Constantin Mierla]

Hello,

the r-uri is added as a Contact address for 3xx replies -- I don't
remember if this is some RFC requirement or just an implementation of
the sl function for 3xx replies (well, I haven't implemented those
function either).

The active branches of the request are added as contact header to the
reply. So you can practically use append_branch() as many times as you
need and then do sl_send_reply("3xx", ...). You don't need to append
headers to replies explicitely.

Cheers,
Daniel
