Caller ID
If your cell phone service offers caller ID, the telephone number of the party
calling your office number displays on your cell phone. The display may reflect
either the full 10-digit telephone number of the caller, or, for inter-office calls,
either the full 10-digit number or an extension number having fewer than 10 digits.
NOTE:
Some cellular phone networks pass only 10-digit caller IDs, while other
networks are more flexible. Those which pass 10-digit numbers only may
prevent you from receiving inter-office caller IDs having fewer than 10 digits
(for example, a 4-digit extension). Ask your system administrator if 10-digit
numbers can be administered and/or check with your cellular service
provider for more information on caller ID support.
Making calls
The following information explains your options when making calls.
Making calls which send office caller ID
EC500 provides an optional office caller ID, which allows your cell phone to look
like your office phone when making calls to other parties connected to your office
telephone system.
Your system administrator can administer your EC500 cell phone to send office
caller ID to operate as described in this section. When administered this way and
you call parties who share your office telephone system, their display shows your
name and office telephone number - not your cell phone number.
NOTE:
If administered to send office caller ID, EC500 operates as described above,
regardless of whether EC500 is enabled or disabled.
Making calls which do not send caller ID
When your EC500 cell phone does not send office caller ID and you call a party
having caller ID, the called party’s display shows your cell phone number. Even if
EC500 is enabled, the caller ID shown is that of the physical phone you are calling
from and not that of your office phone.
