[sr-dev] [kamailio/kamailio] cscf_get_ue_via does not return UE via (#2864)

[Aleksandar Yosifov]

Hi, again and sorry for the late answer.
I analyzed some log/pcap files and the source code too. Unfortunately,
cscf_get_ue_via is legacy, and I do not know why it is implemented that way.
In conclusion, I believe that the changes proposed by you will not affect
the current implementation.
