This is a -ve test to verify whether phone displays duplicate entries.

Steps to reproduce:
1. Create user groups -- 'member' having users 201, 202, 203, 204, 205 and 'consumer' having users 204, 205, 376 (Snom 320 -SIP 6.5.17 )
2. Add a phonebook 'sales' with groups 'member' and 'consumer' under Member user group and groups 'member' and 'consumer' under Consumer user group.
3. Send Profiles and restart the Snom phone. --> Note: there were no duplicate entries on the phone top and in the .htm file of the phone.
4. Now upload a CSV file 'UserDetails' (file attached) to the phonebook 'sales' and send profiles and restart the Snom phone.
5. On the Snom phone TUI press the 'PhoneBk' soft key or the 'Directory' soft button.

Expected Result:
In addition to the entries in the Member User groups, the entries in the CSV file should be displayed on the Snom phone TUI with no duplicate entries.

Actual Result:
The entries in the CSV file are not displayed on the Snom phone TUI, But some duplicate entries are observed as shown in "Snom_TUI_duplicate_entries.jpg".

Observation:
1. Mac-id>.htm file of the phone correctly displays the entries in the phonebook as below, But the phone TUI does not :

tu_0!: 484
tc_0!: none

tn_8!: Preethi Das
tu_8!: 205
tc_8!: none
to_8!: active
tn_9!: Robert Archer
tu_9!: 376
tc_9!: none
to_9!: active

2. Basic upload of CSV file (other than this scenario) works as expected.
