[VoiceOps] Testing DTMF to known conference numbers

[Jared Geiger]

At the end of the day yesterday I decided to test our product to make sure
that our customers could reach conferencing services and not get FAS,
excessive PDD or DTMF failures especially to international destinations. I
went through old calendar invites that had a link to extra numbers for
Microsoft Teams, Zoom, and an Iowa Freeconferencecall.com number. I'd like
to test Cisco Webex but haven't found an invite with extra numbers for them
yet.

I don't know if the list of numbers are meant for public consumption or if
the client is charged per minute of the call even outside of the conference
room.

Yesterday Simwood's blog highlighted what they were doing for their
customers which included creating a jitsi meet instance (opensource webrtc
videoconferencing and screen sharing software) on their infrastructure.
https://blog.simwood.com/2020/03/remote-working-at-simwood-free-stuff/ I
did the same for our customers as a beta "If it helps and works, I know
little about this so no guarantees" service. Our small clients were very
grateful so we'll see how it goes.

If anyone manages a large conference service that I'm overlooking and
either publishes numbers publicly, I'd like to test to make sure calls
complete as expected (at a random time not the top and bottom of the hour).

In an ideal world this would be a good use of a voice peering fabric but I
understand call compensation and regulatory issues can get in the way of
those orgs being successful.
