I have a pcap and can open in Wireshark. Starts with PCMU, switches to T.38. Wireshark (newest, 1.8.3) has trouble dissecting some packets (lots of UNKNOWN PER) and unfortunately I am no expert to tell if there is anything wrong.<br>
<br>Would anybody be able to help in debugging the issue having the PCAP? I can post it somewhere to download.<br><br>Best regards<br><br><div class="gmail_quote">2012/10/17 Michael Collins <span dir="ltr"><<a href="mailto:msc@freeswitch.org" target="_blank">msc@freeswitch.org</a>></span><br>
