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

The minute you call it an Issue you should be filing it on JIRA.
We get countless emails a day to the list so I don't always read them all
so you are lucky I have managed to follow this thread.

https://freeswitch.org/jira

We have a small team and dealing with the mailing list is a volunteer
effort.

Here is also a tip.  Just provide the info to questions asked.  I asked you
to do a diagnostic test for me by adding sleep to the other FS.
Regardless if you can change the production or not, its still relevant to
me what happens when you change it.
