Hi All, I have a 3CX deployment that is giving me continuous issues. The latest issue is related to voicemails. One of the issues is the caller is getting cut off mid sentence when leaving a voicemail. I've had a wireshark capture analysis by 3CX and they advised in the instance I provided that a DTMF 5 tone was detected that is meant to be "save message". I doubt I've getting multiple callers all pressing the 5 key mid sentence when leaving a voice mail Inbound calls are via an Epygi 4 port ISDN BRI gateway (I know its not supported, but it was all that was available in a hurry). Generally this gateway works very well. Does anyone have any ideas what might be causing my DTMF tone, or causing multiple voicemails from being cut short. I have added the MAXVOICEMAILDURATION parameter with a value of 300, but these are being cut off at random intervals as quickly as 12 seconds. The other issue I'm having is the receptionist goes to listed to a voicemail that was left at 9:53am today, but the message prompt advises the message was received yesterday. 3CX v15 running on a Windows 10 i5 NUC.
