DESCRIPTION
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>.
• 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>.
Specify whether to add a prefix number in the callerID name when you make calls
through this trunk connection. The availability of this setting varies depending on
the format of CallerID Name & Number you selected.
Type the SIP user name associated with this extension. The IP phone registering
with the X6004 must provide this for authentication.
Type the SIP password associated with this extension. The IP phone registering
with the X6004 must provide this for authentication.
Select the type of voice coder/decoder (codec) that you want this extension to use
when communicating with the X6004. The following codecs (shown in highest
quality to lowest quality order) are supported by the X6004:
• G.711 a-law (typically used in Europe)
• G.711 u-law (typically used in North America and Japan)
• G.729
• G.723.1 - you must activate support for this codec in the Configuration > PBX
> Server Configuration > Server > Global screen.
• G.726
See Voice Codecs on page 182
When two SIP devices start a SIP session, they must agree on a codec.
If these SIP extensions are assigned to videophones, you must specify the video
codecs used for video calls. The X6004 allows the following video codecs to
passthrough:
• H.261
• H.263
• H.264
• MP4
See Video Codecs on page 183
This column indicates the codec types not used for these extensions. You can add
