Basic Tests:
Checking for physical link: no WAN link
Please check the physical connection of the WAN interface. Cable not plugged or broken?
Test failed.
If diagnostics are successful, but you are still unable to place a call to 88888# then check the
SIP registration status.
Open the SIP Registration Status page using the QX IP PBX management Status menu item
System Status. Besides the SIP registration information for the auto attendant and each con-
nected extension, the Detected Connection Type is shown. If QX IP PBX 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- 46: SIP Registration Status page
QX IP PBX 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 QX IP
PBX in front of the router, or configure NAT traversal manually as explained in
Appendix: Con-
figuring NAT Traversal.
