4.1 GET_TYPE

The GET_TYPE verb returns the conversation type (basic or mapped) of a particular conversation, and whether the

conversation operates in full-duplex or half-duplex mode.

With this information, the TP can determine the correct verbs to issue on this conversation.

AP_UINT16 primary_rc;

AP_UINT32 secondary_rc;

unsigned char tp_id[8];
