<p dir="ltr">Jon hi,</p>
<p dir="ltr">Thanks for that. Yes that is what I am using and it works in all scenarios except the one described above.<br>
I think this is due to the fact that the REFER does not pass through the proxy.</p>
<p dir="ltr">Any ideas?</p>
<p dir="ltr">Thanks.</p>

Hi john<br>
<br>
Not sure if it would work in all your scenarios but check in version 3.0 a<br>
option called "allow_refer_method". It should allow in-dialog REFER requests to<br>
be sent from one leg to another and whitelist the required headers in the sbc<br>
profile.<br>
