Few more questions: The SIP outbound Draft says - while sending Non-REGISTER requests "If the UAC cannot use one of the existing flows, then it SHOULD form a new flow by sending a datagram or opening a new connection to the next hop, as appropriate for the transport protocol."
1. As per this if we create a new flow while sending an INVITE, how do we refesh the flow when keep-alive fails on that flow? Do we need to send ReINVITE/UPDATE or do we need to REGISTER on that new flow/connection? 2. Similarly how do we refresh flows created by other dialog creating requests like SUBSCRIBE? 3. After Call establishment when the flow fails and when remote sends a BYE. That BYE may not reach the UAC as the flow had already failed. What should be the ideal behaviour in this case?
