Thanks.
We use the Tcl IVR API in our project. To test we have used Sockets in the IOS tcl shell environment. An acces via vrl was possible with sockets. The Tcl IVR API does not support sockets. It only supports http. I have not seen any possibility to use VRF with HTTP geturl requests. Without vrf we have no route to the endpoint.
