		<summary type="html">&lt;p&gt;Created page with &amp;quot;You will need to configure the SCTP stack of the operating system yate is running on if you plan to use SIGTRAN. The default configuration on most systems is inadequate for th...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;You will need to configure the SCTP stack of the operating system yate is running on if you plan to use SIGTRAN. The default configuration on most systems is inadequate for the tight timings required in telephony - timeouts range in tens of seconds instead of hundreds of milliseconds.&lt;br /&gt;
&lt;br /&gt;
On this page:&lt;br /&gt;
* [[#Linux configuration|Linux configuration]]&lt;br /&gt;
* [[#Other configuration steps|Other configuration steps]]&lt;br /&gt;
&lt;br /&gt;
== Linux configuration==&lt;br /&gt;
&lt;br /&gt;
The SCTP kernel module must be loaded at boot time so the settings can be applied.&lt;br /&gt;
As root edit the '''/etc/modprobe.preload''' file and add to it the SCTP related lines:&lt;br /&gt;
 &lt;br /&gt;
 # /etc/modprobe.preload: kernel modules to load at boot time.&lt;br /&gt;
 #&lt;br /&gt;
 # other modules are listed here&lt;br /&gt;
 &lt;br /&gt;
 # SCTP must be loaded early for sysctl&lt;br /&gt;
 sctp&lt;br /&gt;
&lt;br /&gt;
The actual settings are in the '''/etc/sysctl.conf''' file that is applied at boot time.&lt;br /&gt;
Edit this file and add the SCTP timeout tweaking lines:&lt;br /&gt;
&lt;br /&gt;
 # /etc/sysctl.conf: kernel sysctl configuration file&lt;br /&gt;
 #&lt;br /&gt;
 # other settings are listed here&lt;br /&gt;
 &lt;br /&gt;
 # SCTP tweaking for SIGTRAN&lt;br /&gt;
 net.sctp.rto_min=200&lt;br /&gt;
 net.sctp.rto_initial=400&lt;br /&gt;
 net.sctp.rto_max=800&lt;br /&gt;
 net.sctp.hb_interval=5000&lt;br /&gt;
&lt;br /&gt;
You can apply the configuration immediately by running (again, as root):&lt;br /&gt;
&lt;br /&gt;
 modprobe sctp&lt;br /&gt;
 sysctl -p&lt;br /&gt;
&lt;br /&gt;
If Yate was already started you must restart it to allow the settings to apply to the SCTP sockets.&lt;br /&gt;
&lt;br /&gt;
==Yate configuration==&lt;br /&gt;
To use SCTP in yate you must configure it in [[SigTransport|sigtransport]] module.&lt;br /&gt;
&lt;br /&gt;
===Example===&lt;br /&gt;
&lt;br /&gt;
In sigtransport.conf:&lt;br /&gt;
&lt;br /&gt;
 [link]&lt;br /&gt;
 type=sctp&lt;br /&gt;
 stream=false&lt;br /&gt;
 local=192.168.168.156:5050&lt;br /&gt;
 remote=192.168.168.200:6999&lt;br /&gt;
&lt;br /&gt;
==Other configuration steps==&lt;br /&gt;
&lt;br /&gt;
* [[Configure M2PA]]&lt;br /&gt;
* [[Configure M2UA]]&lt;br /&gt;
* [[Configure MTP3]]&lt;/div&gt;</summary>
