Replay T.38 Fax from a PCAP or T.38 XML File Window

This page appears when you select Debug Tools > T.38 Player from the Development Tools menu. Use this page if you want to replay a captured PCAP file or a T.38 XML file.

Telephone Number
Enter the number that is dialed over the configured gateway. This parameter must be numeric and may not be longer than 70 digits.
Initial Delay in ms
Enter the delay after which the first T.38 packet is supposed to be sent. This may help to synchronize the fax send simulator with the receiving (real) fax machine.
Check received frames
Select this option if you want to check received frames only. This option only makes sense for XML input.
Enter the trace file
Enter the path to the extracted Wireshark T.38 data stream. Note that full Wireshark without any extractions does not work properly. Alternatively, you can enter a T.38 XML file.
Browse button
Click to locate the trace file.
Send Fax button
Click to start the fax transmission.
