<div>Hi ,</div><div><br></div><div>I am working with the latest revision of Freeswitch and I am having one way audio problem using SILK/8000 codec on B-leg of the call after Session Refresh or on HOLD. This is due to the fact that when FS sends an INVITE out to B-leg it sends 98 in its SDP offer and B-leg responds back with same code but with payload type "120"</div>

</div><div><br></div><div>Freeswitch handles this properly on the initial offer/answer as its using this patch
(<span style="font-family: 'Lucida Grande'; font-size: 12px; font-weight: bold;">tell rtp stack about what remote payload type to expect when the receiving end follows the stupid SHOULD as WONT and sends a different dynamic payload number than the one in the offer</span>)</div>
