[SR-Users] Kamailio SBC+ Freeswitch as media server

Tue Jun 8 09:38:07 CEST 2021

in a Debian system i am running Kamailio 5.5 installed from repo and with
the basic setup i have 2 users 101 & 102 to be able to call each other. So
far so good.
i added Freeswitch in the same system and tried to follow this guide
http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc even
though it is old and there are many changes. Freeswitch is installed from
deb repo as well.
after following the guide i tried to adapt to newer versions of kamailio
and freeswitch, but i am getting errors. The problem is that the users now
are able to register to Kamailio, but unable to call each other.
I can see users being registered in Kamailio:

*root at kamfs: ~ $ kamctl online101102root at kamfs: ~ $*
while when 101 calls 102 i am getting:
