I have a Debian server running Kamailio and i have all my users regiatering and talking to each other. I do create/remove users from Siremis. I have followed the guide from here:
https://www.powerpbx.org/content/kamailio-v5-siremis-v5-debian-v9-mariadb-apache-v1
I would like to add freeswitch to the same server and add conference, voicemail, supplementary services  for my users.
I have given it a try to install freeswitch and tried to configure it accordingly to https://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc
But.now the Siremis gui shows a lot of errors and i cannot login any more.  Since it is a Virtual machine i reverted it back and it works without freeswitch.
How could i integrate freeswitch to my system please?
