OpensSips issue on low bandwidth conditions

  • Our current problem which we encounter on the OpenSIPS server is that we try to create multiple MSRP stream sand  for some of them we receive the 404 response, because of clients being offline(perfectly normal) in other cases we get a 200 response meaning a MSRP session successfully established but in some cases we receive an “Internal server error” response. In the server logs we have these messages:

    On the server side we have OpenSIPS server working over TLS, also we have MSRPRelay working on TLS. On the client side we are using sipsimple.
