Tom, Analog/POTS: AudioCodes seem nice. I have yet to use one extensively, but I have a couple of them lying around that I have played with a bit. They have a TON of configuration options (seriously - if you though Sipura was bad, just wait), which I always appreciate. For one off scenarios, I like the Linksys/Sipura devices. The features aren't bad, they are easily provisioned, and they are stable. There are some quirks, though. For instance, last I checked the 3xxx gateways do not listen for DTMF tones on the PSTN Line when the call has been connected to a SIP server. That's pretty annoying... Digital (PRI hopefully): Cisco. I really have a love/hate relationship with them. Just when I start to appreciate their products, I am reminded of why so many people hate them. When it comes time to activate or renew a service contract, for example (just to get new IOS versions). Anyways, they are expensive but you can find a 2651XM and NM-HDV module on the used market for less than you'd think (still not cheap). It you are buying new gear, on the low end the 2811 + PVDM2 + VWIC2 is a good combo. On the high end, you have got to appreciate the AS5xxxXM, which can easily support eight PRI circuits in 1U. All Cisco gear has standardized versions of IOS that support everything you'd ever need, including: 1) SIP over anything - UDP,TCP,etc 2) T.38 faxing (even as a gateway, obviously) 3) G729a/b/G723 in hardware (DSP) 4) So, so much more -- Kristian Kielhofner _______________________________________________ Astlinux-users mailing list [email protected] http://lists.kriscompanies.com/mailman/listinfo/astlinux-users Donations to support AstLinux are graciously accepted via PayPal to [EMAIL PROTECTED]
