Customizing a Local Contact File (Color Screen Phones)
feature is only applicable to SIP-T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones.
Display called party information allows the IP phone to present the callee identity in addition to
the presentation of caller identity when it receives an incoming call.
The following figure shows an example of screen display when Display Called Party Information
feature is enabled on the phone (a call from Tom (phone number: 1008) to Marry (phone
number: 1009)).

For SIP-T54S/T52S/T48G/T48S/T46G/T46S/T29G IP phones:
You can customize the call information to be displayed on the IP phone as required. IP phones
support five call information display methods: Number+Name, Name, Name+Number, Number
or Full Contact Info (display name<sip:xxx@domain.com>).
The caller information may be too long to be entirely displayed on the phone in a short time.
You can customize the horizontal scroll speed of the caller information when the phone is
ringing, so that you can check the caller information more quickly before picking up the call.
