Hi All, Having an issue with a DID that is not ringing through to an extension I have set up. I have two SIP lines configured in 3CX. With two DID numbers, each number rings an individual extension. The first number rings through to the extension perfectly but the second sounds like it is a foreign ringtone and says 'record your message and then press pound'. Not sure where I am going wrong as the settings are exactly the same for each SIP line. Also just to note, the PBX has registered both lines with the SIP provider. The SIP provider says the issue is with the PBX.
