View Full Version : Blocked UDP

08-17-2006, 09:52 AM
A few of our clients are experiencing Blocked UDP when you view in
System Events. When this happens, all SIP registration will fail. There
are still responses when the SIP servers are PINGed from the Quadro.
Re-registration of SIP accounts will not work, and the Quadro needs to
be rebooted for the SIP registrations to come back up.

These Quadro have been working normally with NAT traversal set to STUN,
but this Blocked UDP issue will happen intermittently and is causing
headache for us when supporting these Quadros.

Any ideas as to why
Blocked UDP happens?
