It could be your ISP serving you a new lease on a small pool of IP
addresses.

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.
I agree that this is ideal (both for security and ease of configuration),
however note that I am using an OpenVPN setup on pfSense with Yealink
phones and Asterisk and have run into intermittent quality problems where
audio will drop out for 10-30 seconds one way during a call. I'm not sure
if this is a hardware problem with my pfSense router, overhead from the VPN
connection, or something else.
