For reading the pcap files, you could use epcap (which uses libpcap)
or Anders Nygren's pran (which reads the pcap file using Erlang):

https://github.com/msantos/epcap
https://github.com/nygge/pran

For fun, I've used epcap to dump HTTP responses, doing the parsing with
httpc (httpc is awesome!):

https://github.com/msantos/perv

You might be able to do something similar and pass off the data to the
Erlang megaco module but I don't know anything about megaco.
