We are in the process of implementing CTP profile for Series 60 phones. Two crucial pieces that I feel are required to implement this are support for audio in duplex mode and implementation of TCS-BIN.
Publicly available SDKs do not indicate their presence. So if they are implemented what would it require to get access to relevant APIs?
What all Nokia Series 60 phones support them?
I would appreciate any suggestions/pointers in this regard.
