Thanks for the reply.  Internal call work just fine.  I'm currently going through all the firewall settings. 

[Auto Attendant answers but sometimes no audio]

Hello,

I've had this ongoing problem for some time now.  It seems to be fairly sporadic but it's happening more lately.  Sometimes when a call comes in the AA will answer but the greeting doesn't play and all that is heard is silence.  If the caller puts in the extension, the call is sent to that extension.  System is on a linux VM with software version 63.0.1.  AA file type is a .wav 16bit 8hz mono uncompressed.  Any help would be appreciated.  Thanks
