The BSSLAP dissector is called by "GSM BSSMAP" dissector. So both dissectors must be enabled.

Providing more details in your question can help to get an answer.

At the end of the paging response message, 3 bytes data can not decode as BSSLAP. And how to decode it via protocol setting or configuration, etc.. Thank you so much.
