Hmmm, Looking directly at the .../channels/chan_sip.c code does not get any clues.
Switch( resp ) ... ... case 480: /* Temporarily Unavailable */ case 404: /* Not Found */ case 410: /* Gone */ case 400: /* Bad Request */ case 500: /* Server error */ case 503: /* Service Unavailable */ if (owner) ast_queue_control(p->owner, AST_CONTROL_CONGESTION); break; Basically the code says that "something happened that we have not written code to deal with the problem so lump it in with other things we don't handle and tell the SIP device on the other then, "Doh!" I found this reference from the "Gods and Generals" at Cisco: http://www.cisco.com/univercd/cc/td/doc/product/voice/sipproxy/relnotes/ solrelnt.htm +++++++++++ "Problem: Server Internal Error might be returned in response to a REGISTER request (CSCds02480) Problem Description: Occasionally, the Cisco SIP Proxy Server returns a "500 Server Internal Error" response to a REGISTER request. This problem occurs primarily during periods of heavy CPU loads and receiving REGISTER requests at a rate equal to or greater than 10 per second. Also, this problem is more likely to occur when running a server farm because the registration information is being updated on multiple machines. This condition is temporary. Recommended Action: Reissue the SIP REGISTER request." ++++++++++++ Like I said, the SIP server is responding with "Doh!" Any more clues as to when this happens?
