<div><div dir="ltr"><div>Hello,</div><div><br></div><div>This is on OpenSIPS 1.9.</div><div><br></div><div>I want to remove all audio codecs except PCMU from an SDP. I have the following config:</div><div><br></div><div><div>

<div> exit;</div><div> }</div></div><div><br></div><div>It does exactly what it's supposed to do, leaving only PCMU in the SDP. The problem is that it also removes the RFC2833 definition.</div><div>
