I have not been able to find any clear explination of the difference between 
1. Adding a "Calling Plan" 
and 
2. Adding a "Additional Phone Number"

Questions... Can zoom user have two different calling plans?
What can a "Calling Plan" do that an "Additional Phone Number" Cannot?
What can a "Additional Phone Number" do that an "Calling Plan" Cannot?

I have a cell phone which I would like to cancel, do I need to transfer it over as an additional phone number?
Does the additional phone number work like an alias for a calling plan? 

So many questions.... Please Advise! 

Im trying to split test between to Zendesk talk and Aircall.

Ive built a call que with 20 user, 10 auto forwarding to 1 external number (aircall), 1 to another external number (zendesk). its on a 45 second round robin between users. The zoom number is not used

The Aircall forward  works as expected a call will present in the que for 45 seconds, if no answer, it moves to the next user, which will forward into zendesk.

looks like zendesk doesnt like warm transfers somehow, as the call is never answered/acknowledged by zendesk. It does appear as an abandoned call in the zendesk console, but u cant answer it,a nd after 45 seconds goes back to the aircall que. .I know it doesnt answer as the specific zendesk ringtone isnt heard, just the zoom one.

Is there a way to force blind transfer to an external number  for a user in a call que? 

cheers

I am the main receptionist at my company.  When I answer calls I used to hear a sound that indicated I had connected with the caller.  This would also allow me to tell when it was most likely a spam call as there would be the very long pause before the caller started talking.  Now when I answer I hear nothing so often not even sure anyone is there unless I see "call ended".  

Given the glaring absence of call control for Zoom Appliances, I've been experimenting with a Yealink SipT31G.  Whilst both of the above functions do what they say on the tin, there doesn't seem to be any way to have both enabled at the same time.  If i have call control enabled, I can click dial from my Zoom client, just the way I did with Skype for Business.  If I then start a meeting (with call control still enabled), the line key assigned for Zoom meetings stays green.  However, if I disable call control, then start a meeting, the assigned line key turns red and I can use it to join the audio portion of the meeting from the phone.

Am I missing something?  Functionality wise, it seems that we have gone backward from where we were.  None of these were an issue with Skype!  Frustration levels are high at the moment - we're trying to provide a seamless experience for our users, but it just seems as though the 'unified' element is missing.  It's all very disparate.  We are primarily a thin client site, so there is no desktop audio.  We currently have old USB phones plugged in to get around this.

I use multiple mobile devices, IPad and Iphone. I have the app downloaded on both and i stay logged in on both. I use my phone for calls and my Ipad for meetings. How can I stop every device from ringing when I get a call through Zoom? it is very disrupting to have every device ringing in the house.
