Status
. Besides the SIP registration information for the auto attendant and each connected
extension, the

router and the STUN is enabled, the detected connection type and the IP address of this
router's WAN port are displayed.

Quadro cannot work behind your router if
Detected Connection Type
is one of the follow-
ing:
•
Unknown connection - unexpected error
•
Symmetric NAT
•
Symmetric Firewall
•
Blocked UDP
If you get one of the above mentioned Detected Connection Types, either connect the
Quadro in front of the router, or configure NAT traversal manually as explained in
Appendix: Configuring NAT Traversal.
