Your friends can join your conference call from a landline or mobile by dialling your Online Number. You can then add them to the conference call in Skype.

To add a mobile or landline caller to a conference call already in progress, when the incoming call window appears, click More > Add to conference.
You can also merge calls. If you click Answer to incoming calls or call contacts individually, you will see more than one ongoing call on your Recent tab. To merge calls simply drag and drop one call to the other.
In the example below, you would click and drag Charlie Kent to James Cooper, Jiro Ishikawa.
