Assigning forwarding rules from C# API

[ShMo]

Hello everyone,

My first post, so I apologize if there is insufficient information.

I am using the 3CX Phone system version 9. I have two laptops (Extensions 1050 and 1051) connected using the 3CX Soft phones (ver 5.0.14900.0). I have an intercom (Extension 1001), which always calls Extension 1050, when its call button is pressed.
I am using a C# application to dynamically forward an incoming call from 1050 to 1051. I am using the examples from the "3CXCallControlAPI_v9/TestCSharp" application that I downloaded.

I am able to assign a 'Forward all' forwarding rule to 1050 from my API. When I monitor the extensions, it lists the correct forwarding rule, as shown in the screenshot :

But the incoming call is not forwarded. Heres the log :

if all you are doing is forwarding calls from extension to extension, why not use the 3CX forwarding rules?

 

[ShMo]

The forwarding rules need to be changed dynamically based on a look up table I am reading from a PLC. The call could be forwarded to one of the ten available extensions, based on a set of rules.
If I set the same rule manually in the 3CX Management console, it works fine.
