Hi All, Sorry for cross-posting this email to PJLIB, but maybe there are some things related. Anyhow! I'm having problems on kamailio v4.0.2 under Fedora 18 64bit and TCP client like iPhone using PJSIP as SIP library. Basically once the iPhone side in close the call (TCP->UDP) I'm getting the error below. Kamailio is running under a VPS without NATed network so it uses a real public address. Furthermore, note that tcp_main is answering to a 192.168.2.98 ip address which is the iPhone client. This looks really strange to me since it should answer directly to the public/port used for the registration and not to a such kind of reserved address. The kamilio configuration is basically the default with a very few changes like NAT, rtpproxy and postgresql backend. This problems doesn't happen at all when using UDP->UDP calls. But I cannot use it because as you certain know UDP connection under iPhone will not work when the application run in background mode. Can someone suggest how to solve this issue or maybe suggest a TCP working solution for iPhone? Thanks in advance. Roberto Fichera.
