Administrator’s Guide for SIP-T2 /T3 /T4 /T5 /CP920 IP Phones

The phone displays the keys with left-to-right order. For example, “favorite,uc_favorite,blf_list” means
the display order is Favorite keys > UC Favorite keys > BLF List keys.
If only one type is configured, the configured type will have the highest priority. For example, “blf_list”
means the IP phone preferentially display the BLF List keys, and remaining keys’ display order is: UC
Favorite keys > Favorite keys (the default order).
Note: If Auto Linekeys feature is enabled (features.auto_linekeys.enable = 1), the Line keys (the line
key type is configured as Line) will be shown first.
Permitted
Values
Blank (the display order: BLF List keys > UC Favorite keys > Favorite keys)
blf_list, uc_favorite, favorite or a combination of them
Default
Blank
Parameter
features.uc_dir.match_tail_number <y0000000000xx>.cfg
Description
It configures the minimum matched digits of the tail numbers of BroadCloud Buddy. When the entered
number matches the tail numbers of a buddy in the buddy directory, the phone will automatically dis-
play the matched results on the phone screen when placing a call.
If it is set to 0, the entered number must exactly match the number of BroadCloud Buddy.
If it is set to other values (for example, 4), the entered number less than 4 digits would not match with
the BroadCloud contact.
Example:
If there is a BroadCloud Buddy name “Sunmy” with the phone number “785656” and the parameter
“features.uc_dir.match_tail_number” is set to “4”, “5656”, “85656” or “785656” would match “Sunmy
(785656)”. “656”, “56” or “6” would not match “Sunmy (785656)”.
