<div>Euan,</div>

<div>I think "IP Authentication" can mean a few different things. I have seen it mostly mean that the provider is not requiring a username/password, but that you must send all SIP messages from a pre-allowed IP address, typically your WAN interface. On CUBE,
you'll need to use the <b>bind </b>command to bind the SIP messages to the interface with the IP address that is allowed by the carrier. Take a look here: <a href="http://www.cisco.com/en/US/docs/ios/voice/cube/configuration/guide/vb_1142_ps5640_TSD_Products_Configuration_Guide_Chapter.html">http://www.cisco.com/en/US/docs/ios/voice/cube/configuration/guide/vb_1142_ps5640_TSD_Products_Configuration_Guide_Chapter.html</a></div>

</div>
<div><br>
</div>
<div>
<div>Hello,
<div><br>
</div>
<div>This may be in the archives but I can't see anything.</div>
<div><br>
</div>
<div>I have a customer site who I am trying to setup a CUBE and a SIP trunk but the provider only accepts IP authentication from our IP address and not username and password authentication. I have searched Google but I cannot find any documentation on how to
get the CUBE (881) to register to the provider (Pulsant here in the UK).</div>
<div><br>
</div>
<div>Can anyone point me in the direction of a config, document or even a heads up how to get it to work?</div>
<div><br>
</div>
<div>Thanks in advance.</div>
<div><br>
</div>
<div>Regards,</div>
<div><br>
