FAQs
Why can I not log in?
To log in to ConnectUC, you’ll need to use your username that was assigned to you. You should have received an email from a Unicom representative with your login information when your extension/user was initially created. (username is typically your work email). If you would like to request app access for the first time or are having difficulty logging in, please reach out to support at support@unicomtelecom.com
Is there a way to reset a password for my user?

How can I find what version of ConnectUC Web I’m using?
You will find the version number you are using on the preferences page in the lower left. There’s also a refresh button there to check for a newer version. Maintaining an up to date app version will keep your user experience bug free and up to date with the latest features.
Do I have the ability to block numbers in SMS?
Yes, if you wish to stop receiving SMS/MMS messages from a number, simply respond with the keyword ‘BLOCK.’ Sending ‘BLOCK’ as a response will ensure the recipient is blocked (Each keyword response is only applicable to the number sending the response).
If you wish to stop blocking a previously blocked number and resume incoming messages, simply respond with the keyword ‘UNBLOCK.’
Additionally, you may also send ‘MSGBL‘ (Abbreviation for ‘Message Black List’) to any number, and you will be provided with a list of currently blacklisted numbers, or confirmation that no numbers are currently being blocked, as seen below.
Using the keywords BLOCK/UNBLOCK will not notify the wireless subscriber that they have been blocked or unblocked.
Should I be getting pop-up notifications of calls and other events?
On a Mac make sure that Chrome or Edge and their helpers have notifications enabled.
Also ensure that pop-ups are allowed by clicking on the Lock icon in the browser’s address bar.
If you are using a Mac, ensure that notifications are enabled for the browser and browser helper that you’re using in Settings -> Notifications.
What firewall ports need to be open outbound for ConnectUC Web and Desktop?
ConnectUC uses encrypted WebSocket connections on ports 443 tcp/udp and 9002 tcp. Additionally audio communications is over DTLS (TLS for UDP) on ports 30000 – 40000 udp.
Chat additionally opens a port 443 to Amazon Chime messaging services. WebSocket URLs connect to servers in the DNS domain ws-messaging.chime.aws.
Calling doesn’t seem to work; what could be wrong?

If port 9002 is blocked the user will see a yellow warning banner.
