Hello,
I am new to Ser. I am able to configure the Ser and
mysql on linux both are working fine I am able to
register with messenger with in our Internal Network.
What I want is to access this server and register it
from out of office employees.
We are using Check Point firewall I configured this
server to allow both way in/out and NATED with public
IP.
For testing purpose I kept all ports opened in the
firewall, for this particular server. I don�t why I am
not able to register it.
What am I doing wrong? Do I need to configure anything
else in SER or Mysql?
Which is better PSTN gateway. We are looking at 1 to 2
FXS port at this time for testing purpose.
Thanks
KD

I think the easiest solution for you would be use of a VPN.

Hard to say what is you filtering/NAT problem. Keep in
mind that getting SIP alone over fw/nat doesn't help
as you want media to get through as well. That's a much
harder problem. Again, VPN is imho a fairly reasonable
choice for remote workers.

? FXS is a PSTN-phone-2-IP gateway, isn't it? The most
popular is cisco's ata.

Might take a closer look at the Checkpoint to see if it is
doing Port Address Translation (PAT) in addition to NAT.
If I recall correctly, the older versions of Checkpoints
software did PAT, which caused folks problems when an app
wanted to use specific tcp/udp port numbers (for example,
when trying to use an non-checkpoint VPN box on the inside
of the checkpoint).

I always thought that was FXO but I periodically confuse these
two abbreviations. Anyway, if folks want to have a low-cost
analog-line gateway, the cheapest I'm aware of are ~1000+ with
four analog ports. That's audiocodes and allied telesyn -- I never
tested them though and my hand-waving guess is that these
products still need to mature.
If anyone is aware of an affordable PSTN gateway, let me know.

the already-mentioned Asterisk Linux PBX could be a good choice for the
low end range. Take a EUR300 PC, a isdn4linux card (or one or the fair priced
digium cards), and you're in.

FXO is Foreign Exchange Office, or the telephone company.
FXS is Foreign Exchange (Something?), the actual telephone device.
If you want to plug in a phone, you must use FXS.
If you want to create a PSTN gateway, you must use FXO.
We have experimented with several FXO cisco devices.
None are too expensive. The Cisco 17xx series is a good
device that accepts VWICS that can be FXO or FXS.
The Cisco 26xx or 36xx with a NM-HDV (?) card accepts
VWICS. I've used the POTS based VWICS and the ISDN based
ones. ISDN is better.
