Hi Dale, Yes, I am trying to overcome the fact that many UA's do not honor record route when they are present. This is a big problem for proxies responsible for call accounting. I know one solution would be to go full B2BUA. However, I want to remain as none-intrusive as possible with the headers so as not to open new cans of worms with regard to interoperability between legs. All I want is to be sure that I get a BYE or any other means for the proxy to know that the call is still persisting, period. Any ideas how this is accomplished in the real world?
