I have just yesterday downloaded the latest version of the 3CX VoIP Phone - Version 4.0.10858.0 I'm using it on Windows XP SP3 I am testing it as a standalone SIP softphone with CallCentric. Everything seems to work fine as far as making and receiving calls. The problem I am having is when I create a phonebook and populate a few names and numbers. It works fine while the phone is still loaded and running. The problem arises when I shut-down the softphone, wait a few moments, and then restart the phone. Now, when I go back to the Phonebook, there are no entries.... no phonebook has loaded? I restart the softphone a half-dozen times, make a couple configuration checks. On seemingly random number of restarts, the phonebook is magically back and readable? But, more often than not, next time I restart the phone, the phonebook is gone again. I have checked that the .ini phonebook files have been created and saved in the Phonebook Contacts and Phones folders: C:\Documents and Settings\Jeff\Local Settings\Application Data\3CX VoIP Phone\Phonebook\Contacts\contacts18.104.22.168.ini and C:\Documents and Settings\Jeff\Local Settings\Application Data\3CX VoIP Phone\Phonebook\Phones\phones22.214.171.124.ini It just seems like it isn't reading the .ini files properly. Anyone else had this problem? Any solution? Or, is it a bug waiting to be fixed?
