Possible causes and solutions for registration failure are as follows:
Reason

Switch to a different network to ensure the device can access the public network.
Enterprise network firewall port restrictions.
Modify the enterprise network firewall settings, open the corresponding ports according to the firewall port configuration requirements of the meeting room connector, and refer to:
Check the configured short number, username, password, and gatekeeper address according to the operation configuration guide to ensure they are correct.

An H.323 account or SIP account can only be registered on one device. If the account is already registered, replace the H.323 account or SIP account.
Service unreachable due to DNS configuration restrictions.
After H.323 device registration, how to resolve the issue of successful content sharing display but the remote end not receiving the shared screen during a meeting?
When multiple H.323 devices share auxiliary streams simultaneously in the same meeting, an individual device may occasionally encounter a situation where the auxiliary stream is shown as sent successfully, but the remote end does not receive the shared screen. In this case, the party sharing the auxiliary stream can first stop sharing and then restart sharing the auxiliary stream.
How to resolve when the device fails H.323 authentication during H.323 registration?

In this case, you can join the meeting by directly dialing the Tencent Meeting number from the registered device, or switch to using SIP for registration and outbound calls.

Why Can't I Add New H.323/SIP Registration Accounts? Is There a Limit on the Number of H.323/SIP Registration Accounts per Enterprise Account?
If you cannot add a new H.323/SIP registration account, it may be because the number of currently created registration accounts has reached the upper limit. The maximum number of H.323/SIP registration accounts that can be created is three times the number of MRA licenses purchased by the enterprise.
