[Freeswitch-users] ReloadXML takes very long time

Fri Oct 26 09:23:12 MSD 2012

Yes it is kind specific to our needs, which is very fast loading of
specific XML in big environments
We have some experience with FreeSWITCH modules, we wrote the Voicemail
module from scratch after the existing one did not fit our need
I think on the FreeSWITCH clustering we were really struggling and this is
were the scaling became very challenging for us
Do you have any good document or reference on good practice to cluster
FreeSWITCH, specifically cluster of FreeSWITCHes that can hold tenth of
thousands of users in a single cluster?
