Hello, The FCP module for SER seems to be approaching to a stable version (no guarranties, though). The module is in charge of 2 functions: - Translation of SIP messages from a private network to a public one (using NAT). - Open and close pinholes in a firewall to allow media sessions through. The module implements the FCP side that communicates with a deamon called fcpd that runs on the firewall itself (developed by iptel: http://www.iptel.org/fcp/). It seems to be reasonably stable now with cvs version of ser from 31/03/03. I'm looking for anyone interested in trying it and provide any feedback (bugs, new features or complains :)). Greetings, Jaime
