we are using SIPControl 2.1 with a Dialogic BRI card.

Since we need to have 4 channels available at the same time I was looking for licenses, but it seems like there are non available for purchase anymore.

So my question: Is this product not sold anymore? If yes, is there a possibilty to gain more than the 2 available channels in the free version? I heared about SIPControl Version 1.5 having 8 channels for free, is this version downloadable at some spot? (I haven't found one)

Thanks for your time,
