Network Conference on Shared Line

[JasonTricom]

We are having a problem using the Network Conference feature on a shared line.

We are running FusionPBX.
We set up the conference type to Network Conference and entered the correct URI.
The network conference works fine if the line is set to private; however once we change the line type to share, we get the following error.

Call Failed!
"Wrong Call id"


The two parties, however, are transferred to the conference room. Our extension is just disconnected.
