I&#39;m still having this issue with random EXCHANGE_ROUTING_ERROR disconnects for users utilizing my inbound DID to connect to my FreeSWITCH server. It&#39;s a predictive dialing application, with one agent session being bridged with multiple calls and transfered back and forth between extensions in my dial plan. After a random number of bridging and transferring, FreeSWITCH suddenly sends a BYE to my DID provider citing an EXCHANGE_ROUTING_ERROR. It does not happen at any one-point in my dial plan, or applications--it just randomly disconnects when a call that the Agent is bridged to hangs-up or is disconnected. It seems to only happen when two external sip profiles are being bridged together, and not when an internal and external profile is being bridged.<div>

I enabled sip trace logging and got the logs below, but I am still at a loss at being able to identify the error or reproduce it consistently. The below log indicates to me that my FS server is initiating sending 2 BYE message to my DID provider (<a href="http://didforsale.com" style="color:rgb(20, 125, 186)" target="_blank">didforsale.com</a>).

 Digging a bit in mod_sofia releaved that it can be caused by a SIP<br> code 482 (loop detected), 483 (too many hops) or 484 (address<br> incomplete).<br> <br> Do a SIP trace to sched more light on what&#39;s happening.<br>
