Thank you David, that info accurately describe the process to connect the 3CXPhone to the PBX. I however meant to refer to the stand alone 3CXPhone, not to the PBX. The stand alone 3CX phone allows you to provision several accounts and it has 5 lines, which sort of suggests that you should be able to set up one voip account per line. I tried with 2 different accounts right in the softphone but was unable to assign a specific voip account to any specific line. I'd like to know how to achieve that.
