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.

I got SER up and running with a whopping total of three "domains"
being served on the same server. It was mostly painless, if missing some
features I'd like to have seen (more on that in later messages.)
What open source products are people using for voice mail, voice menu
prompts (press 1 for sales, press 2 for the executative restroom) and
for conference calls (which include PSTN calls as well as IP phones)?

Hi,
Are there any plans to add SIP Symmetric Response support
(http://www.iptel.org/info/players/ietf/firewall/nat/draft-ietf-sip-symmetri…)
into SER, so that it would be possible to use compliant UAs behind NATs
with SER being on a public IP? The idea is simple: when the SIP packet
is received from UA, the server checks if an empty `rport' parameter
is present in the first Via field, and if yes then compares IP:PORT in
the first Via header with the actual IP:PORT this request came from,
and adds `received' and `rport' parameters into the header if either
doesn't match before forwarding request further.
Then, when replying or forwarding the request, the server checks if
any of received or rport is present and uses it instead of the
UA-provided values in corresponding Via header.
Please let me know if there are work in progress on this, so that
I will not have to reinvent the wheel.
Thanks!

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?

hi,
i have met the same problem with acc. i can get the invite message for accounting,but i can't get the bye message, i also capture the udp packages on ser server, i use MSN for UA, i find the sip messeges like: invite,100 trying,180 ringing ,200 ok(for invite),but when i hangup, there are not bye message, it's like sending bye message from UA to UA directly,while not going throug ser server,so there is not BYE message for accounting, is it true?
how to get the bye message for accounting? please help.

Dear Sirs,
Our company is currently evaluating several freely available SIP
proxy/registrars to extend our VoIP billing engine, which currently
only supports H323, to support SIP as well. We found SER to be one of
the best for our needs: speed, documentation, flexibility - everything
is great. Hovewer, since our billing engine uses Radius for AAA, we need
to get Radius modules working. Unfortunately, we can't compile radius
modules with virgin radiusclient 0.3.2 as suggested in documentation - it
seems that some SIP-specific changes need to be applied to radiusclient
headers, see the following log:

Would you be so kind to provide us with your changes for radiusclient or
point out where that modified version can be downloaded?
Thank you in advance!
On a separate note I would like to ask you to let me know if there is
any progress on pre-paid module discussed on this list recently. Since we
will also need this functionality, perhaps we can team-up to implement it.

I changed this to t_relay() and then I get the BYE
ACC output in the syslog file. This explains something else
(I think). Sometimes the BYE would work, sometimes it would
not make it all the way to the other device (either the PSTN gateway or the
UA). That is probably because forward() simply bounces the
packet via UDP and the UDP can fail ??? t_relay() retries??
Does this make sense?

Hi,
I am trying to create a basic script for routing calls to and from
the PSTN. I have experimented with many scripts over the last month,
this included script is an example. I can use a UA on my
laptop called 'estara' and REGISTER with my ser sip server.
I can make a phone call (INVITE) to the PSTN. I can hang up the call
from either end (BYE) and everything seems to work well.
I am trying to get accounting working. I see the call acceptance
record in my syslog file:
Jan 7 00:21:09 build ser[3507]: ACC: transaction answered: method=INVITE, i-uri=sip:92143357976@build.august.net, o-uri=sip:2143357976@64.90.42.16:5060, call_id= 847b3d22-131d-46b0-abcb-dc8e6a9f32b5(a)192.168.100.100, from= greg <sip:1107@build.august.net>;tag=3a7b9c52, code=200
However, I can't get the 'BYE' event to record the transaction to the
syslog file. The 'BYE' event is bouncing through my SIP server.
Can someone give me a hint?
Thank you,
