I too have Yealink phones in the exact same manner terminating to
several different asterisk installations and have not had any call
quality issues.  Of course there are many variables that have to be
considered with voip over the internet, the firewall itself, the
internet connections on either end and utilization of them, the model
and firmware of the phones themselves and the everything about the
asterisk installation as well.

Mark,

Is your pfsense hardware particularly powerful? Which Yealink models
are you using (latest firmware versions I assume)? I suspect that the
pfsense hardware and/or internet connection is the problem in my case
since asterisk clients on the LAN have not had these problems. Moreover
I seem to be able to rule out the remote networks since I have several
clients in various geographic regions all experiencing the same issue.

Thanks,

Andrew

If you have the option of using OpenVPN on the phones (Grandstream,
Yealink, Snom & maybe others?) that might be better than the possibility
of double nat and other configuration issues that can crop up.
