Thanks for the feedback. In our old telephone system you could define whether the calls are dropped (busy signal) or forwarded to another group/participant / voice box. There are also many other situations where this is useful. A service counter with a cash desk e.g. with 3 employees...

A function we painfully miss is the limitation the number of incoming calls to a call group. We have more telephones than employees who commute between the checkout area, workshop and office. With our old telephone system I could define that a call group would only receive the amount of calls...

Many thanks for your support. With us it was actually due to an "&" at the BLF's. :-)

Good afternoon, For some time now, our Fanvil X7 devices have been cyclically displaying the message "Invalid file". Apparently the phone doesn't like the provisioning file anymore. I have reset one and now I don't get it provisioned anymore, no matter what firmware I use. 3CX recommended or...

Thanks for the link, I'll try and report back

Thank you for your feedback. Yes, there are a total of 34 devices in use, all have the same problem. The newer firmware from the Yealink site has already been tested, unfortunately without improvement.

We have with the Yealink T58A phones the problem that if only one side speaks at a time the quality is good, but if you talk into each other then the outgoing sound is hard to understand. The external caller on the Yealink is always good to understand only hears this one on the Yealink talking...

Here I can tell you the solution if someone has the problem again: The German Telekom does not support outgoing calls with video function. Although there is no camera and nothing like that activated the Yealink seems to send a video data/protocol in the outgoing call. This simply blocks the...

We have 32x Yealink T58A on a Netgear switch S3300-52X and 5x Grandstream HT802 on a 3CX Pro on Linux. There's nothing set yet in terms of QoS or Vlan, especially as I don't know how to set this up properly. Netgear has a port-based Auto-Voip function. It also improves the transmission of faxes...

E164 is deselected and everything configured according to 3CX specifications for Telekom. The crazy thing about us is we can do it with the same phone and the same settings. Not with our client. Difference is with the customer VDSL25 and with us VDSL100 from then on there won't be any problems...

Oh, thank you, I didn't know that. If nothing fundamental is known, I will run a trace to the provider in the hope of getting information there.

Thanks for your feedback. Under the 3CX's phone provisioning, I can find only the codecs G722, G729, Opus, PCMU, PCMA. Nothing else is offered under Add.

Good day, we have a strange problem with a new 3CX installation. 90% of outgoing calls via Telekom are rejected with the message: 488 Not Acceptable Here Dialing the same number with the softclient and headset works, you let the softclient dial the phone in CTI mode it does not work. Not even...

Thanks for your feedback. If I am logged in as an administrator on the RDP server all lines are available and work. If you log in as a user with a username that is also in the 3CXTAPI.ini, no Tapi line is available. However, the Windows client in this session is active and working. Nothing...

We want to install the 3CX Multi Line Tap on our RDP (Terminal) server but the installation routine only allows user names with alphanumeric characters. Our user names have the syntax "x.name". It is not possible to change all usernames. Will there be a new version that can handle"." "-"? or...
