## ◆ tcapsrt_call_matching()

struct tcaphash_context_t * tcapsrt_call_matching | ( | tvbuff_t * | tvb,
|  | packet_info *pinfo | _U_,
|  | proto_tree * | tree,
|  | struct tcapsrt_info_t * | p_tcap_info
| ) |  |

Service Response Time analyze Called just after dissector call Associate a TCAP context to a tcap session and display session related information like the first frame, the last, the session duration, and a uniq session identifier for the filtering

For ETSI tcap, the TCAP context can be reached through three keys

- a key (BEGIN) identifying the session according to the tcap source identifier
- a key (CONT) identifying the established session (src_id and dst_id)
- a key (END) identifying the session according to the tcap destination identifier

For ANSI tcap, the TCAP context is reached through a uniq key

- a key (ANSI) identifying the session according to the tcap identifier

## ◆ tcapsrt_razinfo()

struct tcapsrt_info_t * tcapsrt_razinfo | ( | void |  | ) |

Initialize the Message Info used by the main dissector Data are linked to a TCAP transaction
