[Freeswitch-users] NAPTR and TCP transport

Tue Nov 10 02:35:08 MSK 2015

sure, you can send your calls any time to:

sip:attendant at demo.voxserv.net
sip:attendant at tdemo.voxserv.net

or create NAPTR records in your own domain which point to my SRV records.

But so far, I couldn't find any error in the syntax, and the UDP record
actually works.
