Good evening,
During pre-production testing, we discovered quite odd IPv6 socket
issues. Problems arise when a SIP dialog is initiated from within
Kamailio (e.g. a SIP INVITE message).
Using ngrep, it seems very odd IPv6 sockets are opened, for example:
Where is that bogus part appearing effectively? Inside the SIP packet or
just the output of ngrep about source and destination?
Topoh and header manipulation doesn't have anything to do with
sending/receiving sockets...
Cheers,

Obviously the "1573541542@0:1440" part is bogus, I expect output similar to:

INVITE sip:s@[2001:beef:285:1::3]:5060 SIP/2.0.
When I do a REGISTER from UA using IPv6, the dialog (and return
packets) seem completely normal.
Using IPv4, there's no problem at all.
It seems the socket problems are triggered when:
1. Using the topoh module.
2. When altering From: headers e.g. using uac_replace_from().
When topoh is disabled and no headers are altered, IPv6 works as good
as IPv4.
We could reproduce the problem using Kamailio 4.1.4, 4.1.5 and 4.2.0
on Debian (64-bit).
Please advice what to do.
Thanks in advance!
Best regards,
Kees
