Hey Anca, <div><br></div><div>Please tell me why can't I capture the "Refer-To" header coming from B-leg of the call ? earlier in your reply you said its for A-leg. I can't seem to have it working for B-leg.</div>
<div><br></div></blockquote><div>It doesn't matter if it is A or B. <br>You can take the Refer-To header in the b2b_request route: <a href="http://www.opensips.org/Resources/B2buaTutorial#toc19">http://www.opensips.org/Resources/B2buaTutorial#toc19</a>.<br>

Hi Sam,<br><br>Seems that you have a bad understanding of what the Refer scenario must do. Let's say A and B are in a call. When a Refer message is received from A, the B2B will terminate the call leg with A and will try connect B and the URI in the Refer-To header. The connection is done indeed by sending first an Invite without any SDP to B and doing a late SDP negotiation in 200OK and ACK.<br>
So what you observed, is in fact the wanted behavior.<br><br>Regards,<br>Anca Vamanu<br><br><div class="gmail_quote"><div><div></div><div>On Mon, Aug 22, 2011 at 1:07 PM, Sam Govind <span dir="ltr"><<a href="mailto:govoiper@gmail.com" target="_blank">govoiper@gmail.com</a>></span> wrote:<br>
