I'm trying to make an outbound call to an IPv6 host using the pre-supplied
internal-ipv6 profile.

<action application="bridge"
data="sofia/internal-ipv6/nnnn@ipv6-host.domain"/>

I can ping the host with ping6, and it has a DNS AAAA record. (There is no A
record as the host is a friend's box behind a NAT).

My own box is also behind a NAT, but it has IPv6 connectivity via a tunnel
broker.

The error in the freeswitch.log file is:
[ERR] sofia_reg.c:1344 sofia_reg_handle_sip_r_challenge() No Matching gateway
found

It's quite possible I could be doing something wrong, or there might be a bug
somewhere, or the provided internal-ipv6 profile might need some adjusting...

Suggestions welcome.

Incidentally, if I try it with the external profile, or with my own
external-ipv6 profile (the same as the supplied one, but binding to IPv6
rather than IPv4 addresses), then I get

2008-12-15 16:16:50 [DEBUG] mod_sofia.c:253 sofia_on_hangup()
sofia/external-ipv6/nnnn@ipv6-host.domain Overriding SIP cause 503 with 503
from the other leg

The other party (with a configured FreeSWITCH listening at the IPv6 address in
question) gets the same error upon attempting to call my machine.

Turning on all of the Sofia debugging options reveals the following.

FS sends out the invite (UDP, 1245 bytes).

Then we get:

nta: timer shortened to 500 ms

tport_udp_error: icmp(6) message was truncated (at 832)

The IPv6 address that sent the "message too long" error is presumably that of
a router between my FreeSWITCH box and my friend's FreeSWITCH box.

Is there a way around this?

Are you using SVN trunk? This has been fixed already as far as I
remember!!

From the past emails and the data you have provided so far it makes
me believe you're not on SVN trunk. Also the second email looks like
the far end tries to challenge you and we can't find a matching
gateway. I have tested IPv6 with Snom and FS to FS pretty much
daily. Can you verify you're on SVN trunk and not 1.0.1?

Well its important to know if he's on 1.0.1 or SVN trunk. In 1.0.1
the retry via TCP was disabled on ipv6 and that has now been
corrected. If it gets the message too big error it'll turn around and
requeue the invite on TCP without any user interaction.

Pretty much everything in ipv6 will be over the MTU... on ipv4 we
disabled this because when you talk to things that don't speak TCP you
have a packet over the MTU you try TCP it times out in 30 seconds then
you send it anyway via UDP. So why have a 30 seconds timeout when you
don't need too.

Well I just tested this again with the latest svn trunk

Seems to work fine for me... care to let me at your machine to take a
look?

Works great did an ipv4 call to my FS box and ipv6 out to the
conference box.


Try this out

sofia/internal-ipv6/888@[2001:470:7:ea::2]

(correct the profile for your needs)

Thanks for keeping us updated! It's a lot nicer than, "I wonder whatever happened to Jason and his IPv6 issue?"
