How use TCAP instead of DTAP?

Hi list, I want to integrate the OpenBSC with the Mobicents gateway. However, OpenBSC encapsulates the GSM MAP protocol in a DTAP header, while Mobicents expects a TCAP. The question is: Is possible to use the TCAP protocol in OpenBSC ? PS: Currently I am working with the USSD in OpenBSC. I performed some changes in the code and now we implemented the USSD request,facility and release-complete messages. In other words, now we are able to implement menus in USSD operations. Best Regards
