[SR-Users] Kamailio HA with Virtual IP and multiple Asterisk servers for dispatching

Hello Sammy all of a sudden everything is working.
What I did was to restart one of the servers. To me it seems that
kamctl restart does not reload what is in the memory for the
dispatcher 'dispatcher dump', because I now recall that when started I
actually made a configuration error and made the two asterisks in two
sets. After that I fixed it for the first one (dont remember how) but
for the second one it failed. Now everything seems to be working fine.
IP failover is made with keepalived (Super happy for the moment with it).
Thank you very much for the help.
I will let you know if I have any further issues with this but I hope I won't
Best regards,
Rumen
