Default TBCT functionality question (network vs user)

I currently have 2-B channel tranfer (TBCT) configured on my ISDN-PRI trunks with my service provider and the feature is working. In this situation, the CM is acting as the user and my service provider is acting as the network.

Would I be able to connect an adjunct or other switch behind the CM and expect TBCT to work? In this situation, the CM would be acting as the network and the adjunct or other switch is acting as the user.

I believe that each situation is different and support for the user side functionality does not imply support for the network side functionality.

Thanks for reading.

We do not support the network side to TBCT, unless everything is SIP. With SIP, we support both sides of NCR which involves REFER messages, etc. If you want CM as the network side, it would require either SIP or QSIG. With QSIG, you would be using Path Replacement as opposed to TBCT.
