Hello, can someone tell me how can i add the second line on yealink phone? Is it possible or not in 3CX?Thanks in advance Thanks in advance

Hi @Farkhad,

No, with 3CX we suggest only having one extension per phone. Adding any more extensions to a single device would be using unsupported methods which we don't advise and won't be able to help with.

It works, but expect issues with CSTA(DND) control and stuff like that. You have to do it manually.

In our small office, we want to be able to make private calls and business calls. We have set this up with some manual steps, and as said by Vailis, it is not supported.

Nevertheless, here is how I did it, and any comments on how to do this better is appreciated.

1) Our SIP trunks support passing the caller ID
2) The outbound caller ID is configured on the extension
3) For each phone two extensions are configured, one for business and one for private calls
4) Phones are provisioned to one of the extensions.
5) We use Yealink phones. In the UI, I manually configured the second account and registered it to the second private extension.
6) In the DSS section in the Phone UI, I configured two keys with Type Line, a label and Line1 for the business calls and Line2 for the private calls
7) Under Features, Other, Default account, select the account to be used by default

Strictly speaking the first key is not necessary, because when I dial it uses the Line1 business extension. When pressing the second key for Line2, and then dialing a number, it uses the second extension making a private call.

So far so good. There is a snag, because if you reprovision the phone the custom key is lost. It is possible to protect the personalized configuration with a custom template, in which you set
auto_provision.custom.protect = 1

Or you could prefix personal calls with something and specify the routing on your outbound to use your personal DDI

Yes, that is easier. But we want to use a button, and I did not find how to use 3 digits under a button without starting to dial.
