[SR-Users] Kamailio 5.3.0 and HEPv3 oversized traffic

[Sergiu Pojoga]

Compared to previous versions, under 5.3, one must invoke the
sip_trace_mode() function if you wanted to see the full SIP flow in Homer.
It's not clear from documentation that it's a must function, but it did fix
the problem in my case.

For example:

sip_trace();
sip_trace_mode("t")
