Can the CT license be not configured on the AR that is connected to the VE1 interface of the TDM PBX

In V200R003 and earlier versions, the CT license is used to implement call transfer over a trunk. That is, calls received over one trunk are forwarded over another trunk. The AR connects to the VE1 interface of the TDM PBX:
- When the AR working in SIP AG mode connects to the VE1 interface of the TDM PBX, you only need to configure the value-added service package for voice services.
- When the AR working in PBX mode connects to the VE1 interface of the TDM PBX, users connected to the TDM PBX communicate with only local users. After the value-added service package for voice services is configured, you need to configure CM&BEST license. The CT license is not required.
- When the AR working in PBX mode connects to the VE1 interface of the TDM PBX, users connected to the TDM PBX communicate with external users through the AR. After the value-added service package for voice services is configured, you need to configure the CT license.
