Hello, I have a problem with replaced calls (SIP Replaces header), maybe some of you can help. We have a setup with a back-to-back user agent that sends a re-invite with the replaces option for each call. I can see that my CallCallback class receives the on_replace_request event. I return an 200, "OK" status, but the on_replaced function is never called. I can see that the original call gets disconnected. Am I doing something wrong, or is it something with the user agent? It is an Aastra MX-ONE system. Thanks, Norbert -------------- next part -------------- An HTML attachment was scrubbed...
