This article describes the sections and features commonly used when configuring a Turbine station towards Cloud PBX providers. 
<br><br>
{{Warn| Do not connect a Turbine station directly to the internet on a public IP. Always behind a firewall.}}

{{Note| 
*NAT Keep-Alive setting available from firmware version 4.11 
*Turbine Firmware does not currently support STUN/TURN/ICE, SIP Proxy must use symmetric RTP and SIP rport}}


== Configuration ==
These configuration steps are done via the Turbine web-interface. (We recommend Chrome or Firefox). 
<br>
Except where stated, the parameters in all the procedures are the default settings and are supplied for reference only. 
=== Main settings ===
Please see [[Main_Settings_(IP_Stations)]]
=== Account settings ===
Please see [[Account_Settings_(SIP)]]
=== Call Settings ===
Please see [[Call_Settings_(Pulse)]]

Please see [[Call_Settings_(SIP)]]

== Custom SIP port ==
To use a custom SIP port, it is necessary to use the SIP proxy fields and corresponding port field.

== NAT Keep alive ==
Sends UDP keep-alives every 25 seconds if enabled.

This function will send small UDP packages through the firewall to the SIP server to keep the firewall from closing the SIP connection prematurely.

== Troubleshooting == 
*Station not registering
** Check that you are using the correct credentials and that the SIP Configuration is correct. 
** Check that you have the latest firmware installed. 

*Call will not connect
**Check your firewall settings
**Check Codec settings. Has the SIP station and PBX a common codec configured? 

*No audio or one-way audio
**Check firewall
**Try to disable SIP ALG in your NAT router

*Relay does not trigger on DTMF
**Check that PBX is sending supported DTMF Type. (SIP INFO or RFC2833)
