<p dir="auto">Hi <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/miconda/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/miconda">@miconda</a>,</p>
<p dir="auto">We are using rtpengine indeed, and we are doing a rtpengine_offer() in the request_route. In the failure route we are only doing a uac_auth() and t_relay the message again.</p>
<p dir="auto">However, just for rule things out, if i remove the rtpengine_offer() from the initial outbound route in the request_route(), then the content length is OK. But then of course we don't have the correct SDP.</p>
<p dir="auto">we are using the rtpengine_offer like this for the outbound call in the request_route:<br>
<code class="notranslate">rtpengine_offer("replace-origin replace-session-connection RTP/AVP SDES-no-NULL_HMAC_SHA1_32 SDES-no-NULL_HMAC_SHA1_80 OSRTP=accept")</code></p>
<p dir="auto">So it is definitely caused by the SDP/body being changed in the request_route() in combination with the failure route doing a uac_auth(). But that should be totally fine right?</p>
<p dir="auto">Hope you have more good idea's:)</p>
