Hello Jaime,
check http://developer.berlios.de/project/?group_id=102 This is a FCP daemon for linux 2.4.x
The "official" site is http://fcpd.berlios.de. It contains links to latest versions of our FCP protocol with some examples. Sadly their is not much more information available.
Also check http://pizza4free.de There you can find description of FCP protocol understood by the FCP daemon.
What is needed is a module for ser that will be able to communicate with the FCP daemon.
The communication with the FCP deamon should not be hard thing, because the protocol is quite simple. From my point of view the hardest part is to intercept SIP messages before they are forwarded, until you have received the confirmation of the FCP deamon that it will open a hole in the firewall, or reserved a port on the NAT box for media.
Also look at http://iptel.org/~jiri/fcp - you can find some additional info there.
My colleague has already developed some parts of the module for ser but it doesn't work yet. I will review the code and send it to you if it is usable so you will have some inspiration at least.
Nils (one of the authors of the FCP daemon) is subscribed to this mailing list too so he might provide you with more information regarding the FCP daemon.
For questions about where and how to intercept and change the messages in the transaction management of SER Jiri is your man. I'll be glad to answer questions about the FCP deamon, or fix bugs (their are probably a lot).
Nils

Is anybody aware of any SIP ALG developed or being developed for linux/freebsd?

PS: If nobody is looking at the FCP client side for SER, I would like to contribute in my spare time. Please let me know where should I start and may be I could give it a try.

Subject: Re: [Serusers] FCP support in SER
This piece of work is stalling for some reasons.
First, the gentlemen who was supposed to integrate an FCP client silently stepped away from this assignment. FCP server on linux is working.
The other problem with FCP is there are no real standards. I was expecting the Midcom WG in the IETF to come up with one. Instead, it spent two years with doing things whose use I very strongly doubt.
If there is any volunteer on this mailing list who would wish to complete or create the FCP client module, we will be glad to provide guidance.
Users willing to traverse NATs may consider STUN/UPnP or ALGs as an alternative solution. Users willing to traverse firewalls may need to use an ALG or VPN technology. Unfortunately, NAT/FWs break too many things and there is no one-size-fits-it-all solution addressing all scenarios.

Hi,
I am wondering if this is the right place to ask, but here it goes.
Is the SER software going to incorporate the client side of FCP (Firewall Control Protcol) as a module at some point?
Regards,
Jaime
