If your problem is, that the call has been splitted into 3 files, then you could use the tool mergecap to merge these files into one. Mergecap is part of the wireshark package. After you have merged the tracefiles you should be able to find the rest of the call.

use mergecap. It will merge separeted pcap file into one big pcap, and than open by wireshark.

SYNOPSIS mergecap [ -a ] [ -F <file format=""> ] [ -h ] [ -s <snaplen> ] [ -T <encapsulation type=""> ] [ -v ] -w <outfile>|- <infile> [<infile> ...]

mergecap -w result.pcap 1_part.pcap 2_part.pcap 3_part.pcap ...
