wireless handsets by entering the alias IP address, not the wireless handset
physical IP address.

Determining alias IP addresses
When diagnosing network problems, (for example, to “ping” the wireless
handset), it is useful to know the mapping between the alias IP addresses as
displayed by various Call Server commands and the physical IP address of the
wireless handset. There is no single command which provides this
information; however, the administrator can determine it in two ways:
1 If the wireless handset’s IP address is statically configured, the
administrator can look at the IP address of the wireless handset using the
Admin Menu, which is available when the wireless handset is powered
on. Refer to “Admin Menu options” on page 87 for more information.
2 After the wireless handset is operating and in Standby mode, the
administrator can look at the User Preferences menu to find the alias IP
address of the wireless handset. Refer to “User-defined preferences” on
page 113 for more information.
Troubleshooting coverage issues
Coverage issues are best resolved by adding and/or relocating APs. Overlap
issues may be resolved by reassigning channels to the APs or by relocating
the APs.
