I want to configure skype to allow external calls via a PSTN Gateway. this is the picture of my environment:
- 1 Skype for business 2015 server
- 1 router cisco 2921 voice
- 4 fxo ports
How could i make Configurations?
The majority of the configuration would be on the Cisco Gateway. For the Skype for Business side of the configuration, the documentation starts here: https://technet.microsoft.com/EN-US/library/gg425749.aspx
