Hi All I'm trying to implement a proxy through which Subscribe and Notify could flow. While, the subscribe method is sent successfully, the notify is rejected by proxy with 481-Call/Transaction Does Not Exist. I'm using stateful proxy example to implement the same. Any pointers as to what could be potentially wrong? Br, Sandeep -------------- next part -------------- An HTML attachment was scrubbed...
