Hello Zoom Support Team,

I am developing a mobile application using the Zoom Video SDK with Flutter for both Android and iOS platforms. The application is focused on enabling real-time audio and video calls between two users.

We are experiencing a consistent delay during session joining. It takes around 8 to 10 seconds for both users to connect, and for the audio/video streams to become active.

This delay is negatively affecting the user experience.

We would like your help in understanding the following:

1. Are there known causes or limitations in the Zoom SDK that might result in this delay?

2. Are there recommended optimizations for improving performance on mobile, especially in Flutter integration?

3. Could the issue be related to token generation, SDK initialization, or event listener timing?

We would appreciate any guidance or solutions that can help reduce the session join latency.

Thank you for your support.

Hello.  I am trying to get started with Zoom Phone.  I have the Unlimited Calling Plan.  I can receive calls but cannot make calls.  It tells me, "Sorry, we cannot complete your call.  Your service plan does not support calling this destination."  Is there a setting I need to change, or what?

Hi,

I’ve purchased a Zoom Phone license with the U.S./Canada Unlimited Calling Plan (1 license – active), but I can’t assign a phone number to my user.

When I go to Phone System Management → Users & Rooms, I get this message:

“You need more licenses.”

I’m the account owner and the only user. No numbers are showing up for assignment.

I also can’t manually purchase or add one from Plans and Billing.

This is blocking me from making any calls, and I’m actively paying for the service.

I’ve submitted a support ticket but haven’t received a response yet.

Ticket number: TS1873868

Can someone from Zoom please resolve or escalate this?

Thanks.

Adam

I am seeing faxes from Athenahealth mostly but occasionally others, being split into two separate faxes.

E.g. 1st fax pages 1-6 and then a 2nd fax with pages 7-11.

Oddity is that it's also only one specific location/fax line seeing this behavior.

Path is as follows:

Zoom Fax # "X" > Auto Receptionist "X" that forwards to > EMR fax # "A"

This is the one splitting sometimes

Zoom Fax # "Z" > Auto Receptionist "Z" that forwards to > EMR fax # "A"

This one, and many others configured similarly have never seen this issue

This is all within their normal PBX config, nothing related to online fax.

Our EMR vendor is at a loss.

I cannot find any meaningful config differences between other fax lines, and the one with the issue.

(Beyond the obvious like a different fax # and name).

Hoping someone else has seen similar issues? Have not found anything as of yet...
