Hi
I am getting incorrect source port to Homer web while tracking
outgoing request from my proxy to remote SIP server.

Interface capture (tcpdump) shows exactly what Juha wrote
i.e. random source port for TLS connection.
I always get local TLS listener address as Homer source_port,
clearly not true when comparing to output of tcpdump.
I am calling sip_trace() from branch_route and onsend_route.
Is it even possbile to use siptrace with TLS so that
it records correct TCP (random) source port to Homer?
I tried briefly printing some structure variables in
siptrace/siptrace.c but it seems that real source port
is not available in struct dest_info at that context.
