Hello, Using firmware 5.2.8 of the SPA942 and 3CX Phone System Version6.1.0. I've encountered on issue with the XFER option. The SPA942 has been configured to have 4 lines all registering to the same extension number. If a call is being transfered to this SPA942 all lines will ring. You're able to speak to the person who's transfering the call however when this person is redirecting the call the line goes dead. The transferred call is still in hold (music). This issue occurs only if I accept the call from line 2,3 and 4. Line 1 works fine! Any ideas?
