NO JOY No audio till after on hold

[Alex Hackney]

I've got a small system running in the cloud with 4 endpoints at a client location.
They can receive calls fine. When making calls, there is no initial audio when the call is answered until the calls is put on hold then the audio begins to work.

Its behind a sonicwall firewall, so I'm sure thats it, but not sure how to fix.

So it's also happening between endpoints.

routing between nets is interesting

I appreciate the assumption that I didn't do these two things. I did though. I just can't seem to figure out where the issue is. I think it has to be in the sonicwall.

If you use your google link, this thread is now third lol.

This reminded me that there is always more going on than we think.... How about using Wireshark to see what's going on
