This field displays the caller ID format shown to the callees depending on the setting you

CallerID Name &

Select the caller ID display format you want to use when you make calls.
A caller ID consists of a call ID name (A), a caller ID number (B) and a SIP server IP
address (C). The caller ID has the following format: “A”<B@C>.
The choices are:
(In the following examples, we assume a company representative number is 12345678,
their SIP server IP is 10.1.1.1, a caller extension number is 1111 and DDI/DID number
12345555 can map to the extension 1111.)
• Extension + Extension: Displays the caller’s extension number in A and B. For
example, “1111”<1111@10.1.1.1>.
• Extension + Representative Num.: Displays the caller’s extension number in A and
the SIP trunk’s representative number in B. For example,
“1111”<12345678@10.1.1.1>.
• Representative Num. + Representative Num.: Displays the SIP trunk’s
representative number in A and B. For example, “12345678”<12345678@10.1.1.1>.
Select this format if you don’t want callees to know the caller’s extension number.
• Extension + Representative Num (DDI/DID mapped): Displays the caller’s
extension number in A and the SIP trunk’s DDI/DID mapped representative number in
B. For example, “1111”<12345555@10.1.1.1>. If no DDI/DID is matched, displays
the representative number in B.
• Representative Num (DDI/DID mapped) + Representative Num (DDI/DID
mapped): Displays the SIP trunk’s DDI/DID mapped representative number in both A
and B. For example, “12345555”<12345555@10.1.1.1>. If no DDI/DID is matched,
displays the representative number in A and B.
