2. Voice lost when received Re-INVITE during the active call.

This issue is for S-Series.

You can disable the T.38 option on the SIP trunk settings to overcome the issue. But if you need to use T38 fax at the same time. Please seek help from Yeastar support.

3. Could we use the Hostname as extension registration server address or provisioning?

The answer is no.

The Hostname is basically name for the PBX. If you need it work. You have to request your IT to make DNS mapping for the hostname. But it is not very helpful in most cases.

4. S-Series PBX doesn't support to download the uploaded MOH file from web.

You would need to download it via FTP. How to Access FTP folder?

Login FTP folder: [Your PBX IP address]/sounds/moh/[moh playlist]

 

5. What is the cell battery model used in Yeastar device motherboard?

It is also called CMOS, RTC battery.

2 Models we used for different products: Standard CR2032 & CR1220.

Actually you can check the cell battery model on the battery itself. You don't need to use the same brand of the battery, just match the standard.

 

6. Why it requires password to open a firmware bin file?

It seems the WinRAR default settings makes the Windows try to extract the bin file that prompts you to input password.

In fact, it is not necessary to input password. Just ignore the system behaviour. And use the bin file directly to upgrade.

 

7. Do we need make port mapping for API when connect the S-Series remotely?

Yes, you need to map your local listen port. So that S-Series can push the event normally to your local program.

 

8. Does Cloud PBX support FTP service?

No, for security reason, it's not open for users.

11. Why I get error "500 Server Internal Error" when I try to login the web interface?

It occurs when the flash storage is full. Please try of use SSH console to check which files.

1) Try to input command: df to see which path exists 100% usage or close to 100%.

2) Then enter the path which has 100% usage. Input command: du * -sk to see if any file occupy the storage with abnormal size.

3) Try to use rm command to delete the unnecessary files. (Caution, If you don't know if it is safe to delete, please seek support from Yeastar team.)
