How is it possible to dial out from a CTP System with MCU and ISDN Gateway to another VC System which

has only an ISDN connection.

It is working fine when Dialing in from an External VC system to the MCU.

So the CTP system and the external VC are connected to the MCU with Interop.

So but what about the other direction ?

Someone from the Headoffice wants to call a other company which is using a VC which is only connected

to ISDN. The other Side is not allowed to make outside calls over the ISDN.

So the only possibility is to call the SIDE from the Headoffice where the CTP is located.
