• Receiving an outside call on desk phone or external phone—An outside caller dials the user extension.
The desk phone and external phone ring simultaneously. When the user answers one phone, the other
phone stops ringing. The user can switch from the desk phone to an external phone during a call without
losing the connection. Switching gets supported for incoming and outgoing calls.
• Moving back from an external phone to a desk phone—If a call was initiated to or from the desk phone
and then shifted to the external phone, the call can get shifted back to the desk phone.
• Using midcall features—During a call, users can perform midcall functions, including hold/resume,
transfer, call park, and conference. The external phone cannot resume calls that Cisco Unified IP Phones
put on hold.
The first time that the user views the Reach Me Anywhere setting, no phone numbers display in the drop-down
list box. For Reach Me Anywhere to work for the user, the user must enter a full phone number, including an
outside dial code, area code, and so on. This field does allow a user to enter special characters, such as the
international escape character, +, asterisks, *, and the octothorpe (#).
The user can add a maximum of five phone numbers in the Reach Me Anywhere drop-down list box. The
newest phone number that the user enters displays at the top of the list; the oldest phone number displays at
the bottom.
The user can edit a phone number in the list by pressing backspace on the keyboard. If the user edits a phone
number, the original number continues to display in the list.
To remove all phone numbers from the drop-down list box, the user can click Clear History . Then, the user
can click OK or Cancel in the dialog box that displays.
The user must enter a phone number that is external to the system (outside of the company). The user
must enter a phone number is not part of the dial plan. For example, the user can enter a phone number
for a single-mode mobile (cellular) phone, a smart phone, a dual-mode phone, another IP phone that does
not belong to the system, or for home phone numbers.
Dual-mode phones offer an option to manually hand off calls from the PSTN to WLAN and vice versa.
The external phone must be a Time Division Multiplex (TDM) device.
Reach Me Anywhere gets supported only for Primary Rate Interface (PRI) public switched telephone
network (PSTN) connections.
Tip
Rollover Lines
Rollover lines occur when the same line appearance (extension) displays on the same phone; two or more
lines on the same phone are set up to use the same extension. Rollover lines provide support for call waiting
on some phone models, such as the Cisco Unified IP Phone 6961.
Shared Lines
Shared lines occur when the same line appearance (extension) displays on two different phones.
Most phones with a shared-line appearance can make or receive new calls or resume held calls at the same
time. Incoming calls display on all devices that share a line, and anyone can answer the call. Only one call
remains active at a time on a phone.
Call information (such as calling party or called party) displays on all phones that are sharing a line.
