I'll look at implementing that but it sounds like the "use_init_sdp" parameter is the answer to my issue but it doesn't include the initial SDP message in my re-invite. <div><br></div><div>I am a little confused how to go about this because I found this post by Anca</div>

<div><br></div><div>So in her post the re-INVITE shouldn't have any SDP and then you add the SDP in the the 200OK. My SIP Provider says they will not allow a re-INVITE without a SDP message. And when you read the description for the "use_init_sdp" parameter it says "<span style="font-family:Helvetica,Arial;font-size:12px;text-align:justify;background-color:rgb(255,255,255)">The correct way is to send an Invite without a body in this case, but it has been observed that not many gateways support this". Sure enough my SIP Providers gateways don't support a re-INVITE without SDP.</span></div>

<div>I have a couple of issues with transferring calls when my SIP provider is involved.<div><br></div><div>Issue #1 - Call comes from SIP Provider to Customer A100. Customer A100 picks up. Customer A100 transfers call to Customer A102. While Customer A102's phone is ringing the SIP Provider user on the line doesn't hear anything at all.</div>
<div><br></div><div>Issue #2 - Call comes from Customer A100 to someone on the PSTN network via my SIP Provider. PSTN user picks up. Customer A100 transfers call to Customer A102. This fails because SIP Provider sends me a 603 Decline.</div>
<div><br></div><div><br></div><div>I have talked with my provider and they say both scenarios are due to the fact that I am sending a Re-Invite without any SDP message. On my B2BUA OpenSIPS server I am using the REFER scenario and also have the following in my config</div>
