<b>Subject:</b> [SR-Users] Altering received parameter in Contact</font>

<div>Hello,</div>
<div><br>
</div>
<div>I'm hoping someone can give advice on altering the received parameter in the Contact header on a reply. The situation is that a customer is REGISTERing using TLS, and our Kamailio replies with a 200 OK that includes a Contact header like this:</div>
<div><br>
</div>
<div>Contact: <sip:123456789@xx.xx.102.10:5061;transport=tls>;expires=3600;received="sip:xx.xx.102.10:36051;transport=TLS"</div>
<div><br>
</div>
<div>The customer's device apparently had an issue with this, and the device manufacturer advises that they need the ";transport=TLS" on the received parameter removed. This sounds like a strange requirement, but it's what we've been told. Does anyone know
how to alter this in a Kamailio configuration?</div>
<div><br>
</div>
<div>Our system uses www_authorize to authenticate and is running Kamailio 4.2.1.<br>
</div>
<div><br>
</div>
<div>Thanks in advance for any help!<br>
</div>
