Can't dial an external extension while in a conference call

[vintegrity]

This seems to be a new issue. When in a conference call, once we dial the external number to add them to the call, we can’t dial their extension.

So for example, if we dial a client's main number and they have an extension It doesn’t allow us to input the extension, it doesn't pass the tones it seems.

The version is version 18 Update 2 and I believe they were able to do this in version 16.

An explanation here, as to why DTMF, while in a conference, is not supported.

Thank you, that is the issue. This is for a recruiting office so they often make calls as a group. I guess I'll have to try workarounds.

What you can do is start a new call and transfer it to the conference call instead.

If for instance you're using the 3CX Webclient you can:

1. click on "New Call" while you are in the Conference


2. Dial the external number and navigate through the IVR
3. Transfer the call to the conference by transfering to 700**EXT# where EXT# is the extension number who started the conference (example: 700**101)
