We are having a problem with some user names not being available when people use the company directory. We get the greeting from the company directory every time. We enter the first 3 letters of users last name and sometimes it finds valid names. Other times it responds "No directory entries match your search" when valid names are entered. All users have "Yes" ticked for include in dial by name directory in thirdlane. We are using Asterisk 1.4.44. Thanks in advance for any help.
