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).

Think the FXS is a Foreign Exchange interface intended to tie a ser-accessible gateway to a telephone/pbx line (not to a telephone instrument).

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.
