We've had dozens of Polycom 3.x firmware phones deployed and working
great for years.
Now I've finally been charged with the long-overdue task of figuring
out why newer Polycom devices with 4.x firmware register fine but do
not respond to SIP OPTIONS request and therefore always become
UNREACHABLE if the sip qualify setting is set to yes.
To my dismay, searches for solutions from others who have encountered
this problem have given zero results.
