[Freeswitch-users] Bottleneck between mod_xml_radius and freeradius client?

Sat Sep 3 20:49:25 MSD 2016

Default freeswitch is compiled with freeradius-client 1.1.6 version. This
version has several bugs fixed in 1.1.7.
Please recompile FreeSwitch with 1.1.7 radius lib and also check that
iptables and selinux is disables.
