Feature-Request: Add TCP support for HEP3 listen

[sergey-safarov]

In our installation, we use big INVITE messages (webRTC) and to avoid packet fragmentation we use TCP transport for HEP3 messages.
I found sngrep can parse HEP3 messages via UDP transport but not via TCP.
Please check the attached PCAP file.
hep-tcp.pcap.gz

Wireshark with lua plugin properly parses this.

Hi!

Yes! The only implemented protocol right now is UDP, so I will consider this a feature request that requires an additional setting (eep_listen_proto) to support a HEP listening socket in TCP.

Thanks for reporting!
