TROUBLESHOOTING AND CARE
SYMPTOM: | The device’s Web pages are not accessible. |
SOLUTION A: | Ensure that the ethernet cable connection is secure, and that the link |
| indicators at both ends of the ethernet cable are active. |
SOLUTION B: | Try pinging the phone’s IP address from any Unix or Windows machine |
| connected to the same network. Type: |
| ping www.xxx.yyy.zzz [Enter] |
| (where www.xxx.yyy.zzz is the IP address of the unit). |
SYMPTOM: | The device does not respond to pings. |
SOLUTION A: | Ensure that the ethernet cable connection is secure, and that the link |
| indicators at both ends of the ethernet cable are active. |
SOLUTION B: | Verify that the DHCP server on the network is functioning. |
SOLUTION C: | If you do not have a DHCP server, or want to use a fixed IP address instead, |
| you need to reconfigure the device to use a static network assignment |
| (refer to section 3.2.1). |
SYMPTOM: | The LCD displays "Acquiring IP Address" indefinitely. |
SOLUTION A: | The unit is trying to acquire a DHCP IP address. Ensure that the ethernet |
| cable connection is secure, and that the link indicators at both ends of the |
| ethernet cable are active. |
SOLUTION B: | Verify that the DHCP server on the network is functioning. |
SOLUTION C: | If you do not have a DHCP server, or want to use a fixed IP address instead, |
| you need to reconfigure the device to use a static network assignment |
| (refer to section 3.2.1). |
SYMPTOM: | The automatic DNS discovery process for a VoIP server (MGCP call control |
| agent or SIP server) does not appear to work. |
SOLUTION A: | Ensure that the DNS server is capable of servicing DNS TXT or SRV |
| queries, and that it is configured to respond with the correct server |
| information when queried. |
SOLUTION B: | If the device is configured via DHCP, ensure that the DHCP server has |
| provided the correct DNS server and domain name information. |
SOLUTION C: | If the device network information has been statically assigned (i.e. not via |
| DHCP), ensure that the DNS server IP address is correct, and that the |
| network domain name has been provided and is correct. |
SYMPTOM: | The web browser complains often about errors on the page. |
SOLUTION : | Ensure that the web browser supports frames and that javascript is enabled. |
| Although the device’s internal web pages should be accessible from most |
| modern web browsers, Teledex recommends using Internet Explorer 4.0 or |
| higher, or Netscape 4.0 or higher for optimal results. |
