<p><b>New page</b></p><div>==Description==<br />
<br />
This page describes IPv6 support in the SIP channel.<br />
<br />
==IPv6 address usage==<br />
<br />
When an IPv6 address is specified in a SIP URI it must be enclosed in square brackets.<br><br />
regexroute.conf example:<br />
[default]<br />
^1$=sip/sip:1@[2a00::1:2]<br />
<br />
The URI parser will fail if the address is not enclosed in square brackets.<br><br />
E.g. '''sip/sip:1@2a00::1:2''' will be parsed as host='2a00' and port=':1:2'.<br />
<br />
When an IPv6 address is set in configuration followed by a port it must be enclosed in square brackets. It is not mandatory to put the square brackets when the port is missing.<br><br />
accfile.conf example:<br />
[1]<br />
protocol=sip<br />
username=1<br />
registrar=[2a00::1:2]:9000<br />
<br />
[2]<br />
protocol=sip<br />
username=2<br />
registrar=2a00::1:2<br />
<br />
When an IPv6 address is used to bind to a local interface an interface name can be added after the address.<br><br />
The interface name is required for Link Local addresses (fe80::/10). For these addresses bind will fail if no interface is specified or the address is not assigned to the specified interface.<br><br />
ysipchan.conf example:<br />
[general]<br />
tcp_out_rtp_localip=fe80::1:2%eth0<br />
<br />
[listener udp6]<br />
type=udp<br />
addr=::1%lo<br />
<br />
==IPv6 support enable==<br />
<br />
The global parameter '''ipv6_support''' controls how the addresses are used.<br><br />
If enabled the module will first try IPv6 addresses then IPv4.<br><br />
If disabled the module will always try to bind or connect to IPv4 addresses.<br><br />
ysipchan.conf:<br />
[general]<br />
; ipv6_support: boolean: Enable or disable IPv6 support<br />
; This parameter is applied on reload for new connections or listeners<br />
; This parameter is ignored if yate was not built with IPv6 support<br />
; Defaults to no<br />
;ipv6_support=no<br />
<br />
==Listeners==<br />
<br />
The '''ipv6''' parameter of the listeners controls the listen address family.<br><br />
The parameter is present because the user is required to clearly state what type of listener it should be created (detecting the address family is not enough: a local host name may set in bind address).<br><br />
If global IPv6 support is not enabled the listener won't start.<br><br />
Example:<br />
[listener udp6]<br />
type=udp<br />
addr=2c00::1:2<br />
ipv6=yes<br />
<br />
==Calls==<br />
<br />
IPv6 addresses are handled in SIP URIs.<br><br />
regexroute.conf example:<br />
[default]<br />
^1$=sip/sip:1@[2a00::1:2]<br />
<br />
==Generate SIP messages==<br />
<br />
SIP messages can be generated to IPv6 addresses by setting the '''ip_transport_remoteip''' or '''host''' parameters to an IPv6 address.<br />
<br />
==Line registration==<br />
<br />
Lines can be registered to an IPv6 registrar by setting an IPv6 address or domain name.<br />
<br />
==NOTES==<br />
* The local and remote address family must always be the same. E.g. trying to send a message from a local IPv4 address to a remote IPv6 address (or IPv6 to IPv4) will fail.<br />
Wrong configuration example:<br><br />
ysipchan.conf:<br />
[listener udp4]<br />
type=udp<br />
addr=10.0.0.1<br />
<br />
regexroute.conf:<br />
[default]<br />
^1$=sip/sip:1@[2a00::1:2];oconnection_id=udp4<br />
