Calling from Cisco Spark to Skype for Business

[SamSaul]

Hi there, 

We got users with Cisco Spark accounts and couple of SX20 connected to Cisco Spark infrastructure. We want to call/video with users who are having a Skype for Business accounts and vice-versa. 

Is this possible right out of the box? (Because both got SIP URI)  Or we need to do configuration on both sides to get this thing working?

Appreciate any help and pointing to the right direction. 

Thanks. 

Regards, 

Sam Saul
