Support Services - Additional Phones table can not be sorted by phone model when no device is present

SWVX-12466 Additional Phones table can not be sorted by phone model when no device is present

Validation Date: 1/11/2017
Affects Version: 6.6.0.1 - 6.6.0.4
Resolved Version: 6.7 

Description: When sorting additional phones on the manage phones tab for an extension with multiple Additional Phones, if there is an Additional Phone configured with the phone model left blank, the list is un-sortable by phone model.  This was caused by an issue in the complex sorting algorithm used for this function which would generate an incorrect process based on a non-string entry for phone model.
