The system has detected a PSTN call from an IP Phone
(UA) that is not registered correctly. To prevent
abuse, all UA's must register with our proxy server
before they can place a PSTN call. Common reasons
for your UA not to be registered are:
PROBLEM: Incorrectly set USERID (phone
number) or PASSWORD in the UA
SOLUTION: Make sure your USERID and PASSWORD are set
correctly. Re-enter them if necessary.
PROBLEM: "Registration"
is set to "Never" or "No" in the
UA's configuration
SOLUTION: Modify your UA's configuration to force
it to register before placing a call.
PROBLEM: Call placed too soon after
registration
SOLUTION: Wait at least 5 seconds after successful
registration before making a PSTN call.
