Simple purpose: translate pcap sip session to sipp call flow.
Read from a pcap file all sip messages included in a sip session, identified by callid, and then it generates two sipp xml files, named client_scenario.xml and server_scenario.xml. The content of those files is the replica of all messages sent and received by the client or the server, as CDATA content.
Every send message in sipp scenarios is always delayed by a pause of 50 milliseconds, you can decide to remove the pause or change the value.
For the server scenario, the following sip headers are completely replaced by sipp well known keywords:
via is replaced by [last_Via:]
call-id is replaced by [last_Call-ID:]
from is replaced by [last_From:]
cseq is replaced by [last_CSeq:]
to is replaced by [last_To:];tag=[call_number]
record-route is replaced by [last_Record-route:]
contact is replaced by Contact: sip:[local_ip]:[local_port];transport=[transport]
