Latest public release version of 3CX. VoIP provider uses Broadsoft/Broadworks. We have issue where callers don't get any music on hold during attended transfers. I can fix this by setting VoIP Provider to PBX Supplies Audio. However this breaks inbound faxing. (Fax answers then hangs up after about 15 seconds). Anyone got any ideas? I can post logs but unsure if they will show much. Hoping this is some sort of known issue. I am hoping version 9 will fix it.
