Dear user,

Thank you for your feedback! May I ask if you mean the login account is an admin account? The Extension Groups menu and CDR menu will disappear after upgrading the firmware version? Could you kindly send me a private message with the remote access of your UCM63xx device? We can try to log in your UCM63xx device remotely to troubleshoot this issue. Please kindly upgrade your device to so that we can see this issue directly after login. Thanks for your testing!

Thank you!


Please DM me the configurations you have set, and we can troubleshoot it.

Yes, it is set this way intentionally. However, I’ll bring up this feedback internally to see if this can be updated to be more customizable.

Thank you for the feedback. I’ll bring up this issue with the team.


If you could at least enter the numerals 6-9 (it wouldn’t need to be in the drop down) and have the numeral entered (as long as it was 1-10) that would be great. I know using drop downs are a simple way to check for entry parameters, but in this case it is REALLY limiting for the customers that we use the UCM for. Thank you for all your help!


Dear user,

Thank you for sharing your suggestions with us! We will share your usggestions internally with our development team and evaluate your suggestions. Thanks for your testing!

Thank you!


Im wondering if this is related to us having used the online migration tool from from a UCM6510 to the 6308, I recall a issue we had a year ago, that it was somthing to do with a change in database types and if you had used the migration tool you have a old database, however this got fixed in next release firmware back then. Is this the same issue reappearing again ?


I have grabbed spare UCM6308, factory reset it, upgraded it to and the GUI appears fine, then restored a backup from the working UCM6308 (also running with the GUI issues) and after restoring it on the spare UCM6308 the GUI is now missing Extensions menu item and CDR and other strange things.


Dear user,

Thank you for your feedback! For the Extension Group menu and CDR menu missing issue, do you have the original backup file in the UCM6308? Then, we can try to reproduce this issue with our own devices. Thanks for your testing!

Thank you!


Where is this “online migration tool” located?
We have not found it…


Dear user,

Thank you for your feedback! Please kindly share your original backup file from the UCM6510 to us so that we can check if there is any abnormal data in your backup file. You can share your UCM6510 backup file with me in the private message, and we will generate a normal UCM6308 backup file for your device. Thanks for your testing!

Thank you!


While I support this ability for greater flexibility and customization and also think it’s strange that we allow 10 but not 6-9, could you provide some example scenarios where these exact number of registrations is necessary?


Certainly, we just installed multiple doctor clinics and use 6 concurrent for all incoming answering positions at each clinic. We also just installed numerous schools using 5-8 concurrent for Main answering positions as well as department positions. We also setup hotels with 6-7 concurrent for Main incoming answering positions. We use concurrent to allow easy monitoring and setup of voicemail indicators on each phone. As a rule we keep the number of concurrent extensions to the exact number of phones we have setup as a security aid and “hacking” prevention. We many, many times have more than 5 concurrent, but seldom have 9 or 10. This is definitely a limitation of our setups of systems, and while not a huge security concern, we have had systems hacked in the past which led us to instigate numerous safeguards, which exact number of concurrent connections is one. My question is, why deny the ability to have 6,7,8 or 9 connections able to be programmed?


Dear user,

May I ask if you can share the UCM6308 backup file (before restoring to another UCM6308) and UCM6510 backup file (original backup file, before restoring to a UCM6308) with us in that private message? We can troubleshoot the correpsonding issues based on your backup file and see if any data is abnormal in the backup files. Thanks for your testing!

Thank you!


Thank you! We will bring up this feedback with our team.


Dear user,

Could you kindly share the UCM6308 backup file and UCM6510 backup file to us for troubleshooting? We can help you troubleshoot the Web UI access issue after restoring the UCM6308 with UCM6510 backup file, and troubleshoot the CDR/Extension Group menu missing issue after restoring the UCM6308 with another UCM6308 backup file. We need both backup files respectively so that we can check if there is any abnormal data in the backup file. You can share the backup file download link in the private message I sent to you. Thanks for your testing!

Thank you!

Dear user,

Thank you for your feedback! Since we cannot reproduce this issue, could you kindly how you reproduce this issue? After restoring the UCM63xx device with UCM6510 backup file or using a UCM63xx’s backup file for restoring? Could you kindly share the original backup file with us so that we can try to reproduce this issue locally. Thanks for your testing!

Thank you!


The cause of the issue has been found, and it will be fixed in an upcoming update to this release. Thank you for your feedback.


Dear user,

Thank you for waiting! As we talked through the private message, based on our investigation, there is a known bug related to the issue you mentioned in that ticket and we will release another UCM63xx firmware version to fix that bug within 1 - 2 weeks. If you want to get fixed asap, you can provide SSH access to us so that we can remotely access your UCM6308 to fix this issue. Please enable the SSH access on the Web UI and provide the public address and admin username+password to us, and we can fix this issue in your UCM6308 remotely (you can share the required info with us through that private message). Thanks for your testing!

Thank you!


Another thing
In the call queue tab there is a satisfaction survey where the audio is customizable (we can add customizable audio to our liking)
However, at the end of the survey there is an audio confirming the vote in English and we cannot change this, making it unfeasible to use the satisfaction survey if your default language is not English.
This option could also be customizable or if this is where we change this audio
