pidgin 2.13 + pidgin-sipe

So I installed on Ubuntu18.04 pidgin 2.13 and pidgin-sipe.

Although I can make calls without issues, when people try to call me, I only get a pop-up window saying there is a call and not an actual call sound. found that 2.12 should have supported this in the sound lists, but there is no incoming call to select there.

Any ideas to get this integrated?
