Freeswitch - more particularly, sofia - does not use the standard Linux
libc resolver. 

For more insight, see:


As far as I know, there is no way to get sresolv to use /etc/hosts. Your
best bet is to run a DNS cache of your own (e.g. dnsmasq) and alias the
desired hostname there, then put that in your DNS query resolution path.
