Next step in Update 7 with stability-focused fixes.​

Following the successful Alpha and Beta releases of Version 20 Update 7, we are now releasing the Release Candidate. This build focuses on stability and addresses issues reported by the community, support and QA teams.

Amazon AWS S3 Support for Remote Archiving

I missed the Beta version and just upgrade that on our NFR. But RC not showing.
 
Hi @tronic ,

Can you check what version the dashboard is showing? The RC should be showing: Version 20.0 Update 7 (Build 979).

Thanks,
KS.

You need to upgrade the whole way alpha, beta to rc...
 
There are two issues with this new version I do not understand:

Remote storage partially configured

SFTP is configured, but when I select any of the categories for archivinng (chat, fax, recordings, voicemail) I'm getting permission denied - even with system owners. I can reproduce the issue on 2 systems. Is this a bug? What is the intended way to configure the remote storage? Why do we need to display such a large banner on the system overview page?

DATEV integration

Per blog post an 8SC+ Enterprise license is needed, but I can't find this feature anywhere? (16SC Enterprise NFR)

Edit (found it):
Edit2 (translation):
DATEV-Integration for Windows Softphone ( legacy Client v18):
Admin-Console → Users → Options → Enable client-side DATEV integration → Save.

Hi @pace-IT-DL,

Do the logs show something? Is it permission denied to save the setting, or the SFTP is giving permission denied when trying to write a file?

Hi,

That's the RC - on the Dashboard it's labeled as Beta in all the pre-release versions so it stands out that it's not for production.

Alright, I wasn't aware the message was printed by the SFTP-Server.

So, yes, this message just means the permissions on the file system.

Did you try prepending the folder names with username/ , like this:

Found a small bug but we cant use the call log effectively without it. See the screenshot below,

To reproduce this issue, try searching the call log using a custom date, the dates start counting down quick cycling through the days and months, focus on the url at the top it starts running

Is there any update regarding a timeframe for when we might see the return of department phonebooks? A feature that is sorely missed in our org. I read it was in the pipeline but that was back in March...

Maybe U8.. This no return, it wasnt there before. It is complete new feature.
 
Are the Grafana dashboards available for MS SQL anywhere?
 
I've been testing release candidate V20.0 Update 7 (Build 979 Beta) and can see that we are now presented with an error on the dashboard that states "Remote storage is not configured. It is required to keep your system performant and easily updatable. Set Up Remote Storage"

We self-host VMs for our customer base on our own platform and as such we keep backups of each virtual machine to manage any rollbacks.

Is there a parameter available to us so we can disable the alert and if not can you expose one to the web UI?

I've just opened a support ticket for official support, but I wanted to make this post just to see if anyone else is experiencing this or if I have a config issue.

If you have a deployment on the RC that utilizes trunks with a Registrar/Server IP, an outbound proxy, and an Alternative Proxy (entered on the Options tab), can you check to see if your outbound calls are being routed via the outbound proxy and then to the Registrar/Server as expected?

Ours were on previous builds but are not on the RC.

EDIT: In case anyone else comes across this, it appears that removing the trunk's alternative proxy field, saving, and then adding it back resolves the problem.

IN Version 20.0 Update 7 (Build 1019 Beta) this issue is still present you cant search with a custom date range its broken.

Is there a better spot to submit bugs found in the beta testing?

The forum is the space for this, or a ticket if it needs more immediate reaction. We are actively monitoring the release threads. I see your post in the RC2 thread too. I will pick up the conversation there.
