Actually, you can view the ttl from the states staus in pfsense. I've never
had this issue, but the states viewer allows you to see what you need to
there.

Are you sure this is only for remote workers?

Does it do the same short registrations when on the LAN?

I wonder who thought that was a good idea?

Take a trace of the registrations.  Compare the 'expires' time returned
from the sipXregistrar (as seen in the logs or on the wire between
sipXecs and the pfsense) to what the phone receives.  It may be that the
pfsense is artificially shortening the registration as a NAT keepalive
mechanism (some systems do this - sipXecs does not).
