[Freeswitch-users] [NOTICE] sofia.c: [INCOMPATIBLE DESTINATION] (setting up NAPTR records?)

[Ravi sanyal]

This is a follow up to the previous problem.

I was able to fix the certificates and stop the codec error, however it's
still getting INCOMPATIBLE DESTINATION and hanging up as a result.

the debug log looks like this:

I think it's something to do with SCTP, but knowing nothing of this
standard, I am not sure if this is the problem i'm facing. I'm guessing it
may be not getting the required information between, since if it is trying
to send through sctp ports, my server is not currently set up for that.

So how do you set up sctp on freeswitch? i have an article im looking at:
https://wiki.freeswitch.org/wiki/SIP_TLS

which mentions NAPTR and SRV records. Do you need to set up a DNS server to
make NAPTR records?
