<p>UAC--udp--UAS--tcp--UAS</p>
<p>Additional information: it's only happens when UAC send INVITE with ";transport=udp" attribute:</p>
<pre>INVITE sip:xxxxxxx@sip.domain.com;transport=udp SIP/2.0</pre>
<pre> </pre>
<pre> </pre>
<pre>So question is how to avoid appending transport attribute that come from UAC when forwarding this INVITE to upstream UAS?</pre>
<pre> </pre>
<pre>Thanks in advance.</pre>

<p>Dear All!</p>

<p>After upgrading from opensips 1.6.4 to latest trunk I have error when call goes through SIP TCP gateway with transport=tcp.</p>
<p>Opensips append ";transport=udp" to INVITE requests even when I specify diefferent transport in dr_gateways.</p>
<p>INVITE sip:xxxxxxx@x.x.x.x:5060;transport=tcp;transport=udp SIP/2.0</p>
<p>My dr_gateways table have record:</p>
<p><span class="Apple-style-span" style="white-space: pre-wrap;"># select * from dr_gateways;</span></p>
