200Appendix B Troubleshooting WLAN IP Telephony installations
The handset sends a handshake to the WLAN IP Telephony Manager 2245 every 30 seconds. If no response is received from the WLAN IP Telephony Manager 2245, the handset tries four more times, for a total of five attempts. If none of these get a response from the WLAN IP Telephony Manager 2245, the handset attempts to find a different AP and repeats the above handshake sequence. If the handset cannot find another AP or the second attempt fails, the No SVP Response message appears on the handset LCD display.
Diagnostic Tools
Run Site Survey, Diagnostics Mode, and Syslog Mode are provided to assist the WLAN administrator to evaluate the functioning of the handset and the VoWLAN system. These tools are enabled from the handset Admin menu.
Run Site Survey for the WLAN Handset 2210/2211/2212
Site Survey is used to evaluate the facility coverage before certifying that an installation is complete. It can also be used at any time to evaluate coverage by testing signal strength, to gain information about an AP, and to scan an area to look for all APs, regardless of ESSID. The information available through Site Survey includes:
•ESSID
•beacon interval
•information regarding support of various protocols and standards, as required
•current security configuration
When Run Site Survey begins, it is in single ESSID mode. Press the Any soft key to switch to all APs (regardless of ESSID) mode; the Any soft key changes to MyID. The display looks like the following in multiple AP mode:
111111 | 444 |
111111 | 444 |
111111 | 444 |
111111 | 444 |
MyID | Detl |

where
111111 = last three octets of the ESSID for the discovered AP
