QuadroM32x Manual I: Installation Guide Appendix: Checking the Connections
If diagnostics are successful, but you are still unable to place a call to 899# then check the
SIP registration status.
Open the SIP Registration Status page using the Quadro management System menu item
Status. Besides the SIP registration information for the auto attendant and each connected
extension, the Detected Connection Type is shown. If Quadro is placed behind a NAT
router and the STUN is enabled, the detected connection type and the IP address of this
router's WAN port are displayed.
Fig. I-54: SIP Registration Status page
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 Qu-
adro in front of the router, or configure NAT traversal manually as explained in
Appendix:
Configuring NAT Traversal.
