Known Issues

  • It always queries the provisioning configuration file using the MAC address associated to the LAN interface even when only the WAN interface is plugged to the network;
  • it is not possible to use a sub path when using provisioning via UDP, you can only specify an IP address or an host name;
  • Generation of DTMF on FXS port (RFC2833) is either not done or incorrect (very short tone, and rapid dtmf events cause wrong dtmf sequence). When using with a phone this is not a problem, but when using to feed an analog PBX that has an IVR it causes failures.


Configuration Tips

  • DHCP Server on the LAN port can be enabled/disabled with option P5001 (# Enable LAN DHCP. 0 - No, 1 - Yes)
  • Details for all options can be found in the configuration template: config-template.zip
  • To see all config fields without the template, log into the web gui and view the HTML page source (CTRL-U in Firefox)
  • When naming config files for provisioning, use the MAC address printed on the label on the bottom of the device (same as the one on the box)
  • Serial settings for console port: 115,200bps, 8,N,1, flow control off
