[SR-Users] SIP between IPv4 and IPv6 agents

[Komáromi Péter]

Hello all,

I have a properly working kamailio on my computer. I can register from user agents using IPv4, and they are able to call each other (with and without proxy as well). So it seems to be ok.
But! If I try to switch the IP addresses to IPv6, the calls between the two hosts are ok, but I cannot register to the server with them and cannot call each other. 

When I start kamailio:   # /etc/init.d/kamailio start
I get the followings:

Starting kamailio: kamailioListening on 
             udp: 127.0.0.1 [127.0.0.1]:5060
             udp: 192.168.124.140 [192.168.124.140]:5060
             tcp: 127.0.0.1 [127.0.0.1]:5060
             tcp: 192.168.124.140 [192.168.124.140]:5060
Aliases: 
             tcp: ubuntu:5060
             tcp: localhost:5060
             tcp: localhost.localdomain:5060
             udp: ubuntu:5060
             udp: localhost:5060
             udp: localhost.localdomain:5060

So it listens only on IPv4 address socket. There is no IPv6 socket. Is it the normal working, if the interface has both IPv4 and IPv6 address?
If yes, how can I manage the registering from the IPv6 agents?

Peter
