Believe it or not FXS gateways are not supported in v15 as of yet, and you would have to know to read through this post to know that:

They are saying Sept/Oct timeframe for SP2 to bring the templates back!
I've created a paging dial code, but the paging option no longer shows up under the ring strategy menu when creating a ring group. Can anybody else confirm this issue in v15?
For the non cloud version, you put the template in the following path:
C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\(your unique provisioning code)\CustomTemplates\phones
Then you may need to restart all services, and the template will show up for you.
On version 14, I get the attached error (PhoneSystemException:Unknown variable) when trying to assign the CP860 to an extension using the templates provided on this thread. With IIS as the webserver, any help appreciated.
