[Freeswitch-users] Audio cut off at the begin of the verto call to sip external voicemail

Hello Anthony,

At this replicated scenario, the box I am calling on SIP is FS.
But on real scenario, the box I am calling on SIP is not Freeswitch, it is
an external voicemail server and the initial message have audio cut off.

Thanks for the information about variable ringback, I am already using on
real scenario.

One strange thing is if I use the codec OPUS at verto, this issue doesn't
happen.
But I need to use codec PCMU to avoid audio transcoding.

Let me know if you need more information to debug this issue.

Best Regards,
Jose Lopes
