ipDTL will allow up to 6 concurrent calls, with a Gold Subscription, or two with a Silver subscription.

Note: ipDTL has multiple layouts, which can be selected at the very top of the page. Some layouts have more capacity than others, so be sure to choose a layout which allows the desired number of calls.

Add additional destinations by simply clicking their name to connect. You can balance levels in the virtual mixer as each destination is assigned to its own channel, and also record up to four channels (with a Gold subscription) in the Play/Rec section.
