[SR-Users] Via header line missing

2018-09-07 Thread Karlheinz Knapp 
Hi,

hm the only reason why I'm playing with kamailio is that it should be
able to translate IPv6 from customer phones behind Fritz!Box (NAT) to IPv4
used by the provider (which is not able to handle IPv6).
But it looks that he accept in general the packet with 2 Via lines (also
with IPv6 as address) and send a normal reply. The second Via is not
needed, because he have to send to the first Via.
And if it really comes to trouble, I can remove it with kamailio :)

If it is not possible to make a complete translation with kamailio, then I
have to search again for an other solution.

But still: why is this one Via line not transmitted on the IPv6 side?
Only when I do some modifications it appears magically. That's not a normal
behaviour in my opinion.

If you or Henning can not reproduce this behaviour, then it's possible that
I start TeamViewer
and I can show this on our installation (only at normal working hours).
Btw. I use sngrep to display all the messages, but it works stable and
reliable.

Best regards,
i.A. Bernd

[SR-Users] Via header line missing

2018-09-06 Thread Karlheinz Knapp 
Hi,

of course kamailio is listening on IPv4 and IPv6.

Register coming from IPv6 and goes out on IPv4:

The same answer on th IPv6 side after kamailio without something special:

It contains no Via header!!!

If I add my append_hf()
append_hf("Via: SIP/2.0/UDP
[2a05:e2c1:2::111];branch=$sel(via[1].branch);rport=5060\r\n", "To");
msg_apply_changes();

I get:

With the original Via header !!!

If I add a second Via with append_hf()

append_hf("Via: SIP/2.0/UDP
[2a05:e2c2:0:401:3002:AA:754A:F475]:5060;rport\r\n", "To");
append_hf("Via: SIP/2.0/UDP
[2a05:e2c1:2::111];branch=$sel(via[1].branch);rport=5060\r\n", "To");
msg_apply_changes();

I can see this additional line in the IPv6 packet too.

But since I don't have the right branch, PhonerLite starts a new
registration instead of reregister with username password.

[SR-Users] Via header line missing

2018-09-05 Thread Karlheinz Knapp 
Hi,

we want to use kamailio as a IPv6 to IPv4 proxy.
IPv4 to IPv4 bridging with NAT works.

If we come from an IPv6 address, the registration packet is send via IPv4
to the provider.
He answers with 401 Unauthorized and one Via line in the header.
On the IPv6 side was no Via line in the packet.

So I tried to add one line by hand using an onreply_route and append_hf(),
msg_apply_changes()
To my suprise, this line does never appear, but the original Via line is
now in the packet !!!
If I add now additional Via header lines, they appear in the packet too.

This looks realy like a bug to me.

A solution is needed, because the phone does not respond to the 401 with
user and password.
It starts a new registration instead.

Maybe I can fix it with my additional Via linem but I need the original
branch ID (I think)
How can I get this?

Btw. we have this behaviour with 4.4.2 and 5.1.5

If I get no answer during the next 12 hours I'll try 3.3.7

Best regards

[SR-Users] Ipv6_to_ipv4

2018-09-04 Thread Karlheinz Knapp 
i have tested the sample config from:
https://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6

i found that i can register with v4 to kamailio and to the provider
