Hello list ! I don't have the money to test out all the products and reading the manuals is not always that enlightening... Does someone here know a good gateway-product that lets analogue telephones communicate with an Asterisk-server. I have found the Grandstream GXW-400x to be able to add SIP-accounts to analogue telephone devices that are connected to the FXS-ports. Moreover this product has a backup-PSTN line for emergency calls and backup. Could you advice other products/manufacturers ?

I'm far from an expert, but in my experience, at _that_ price range you don't have a lot of products to choose from, the Cisco SPA3102 is similar to what you are describing (Plus it's also a PSTN GW). Of this kind, I used GXW-4004 and Linksys PAP2, SPA3000 (the Cisco 3102 predecesor), also some larger AddPac ATAs (www.addpac.com) with excellent results, all of them have their pros and cons. The Digium TDM410 cards and they have a very good price/quality relation, plus they are intended for asterisk, plus you are supporting asterisk development.

Analog was not so great. We also tried to convert some Cisco VG-224s to SIP with limited success. I don't recommend using either of those (plus they are expensive...) Grandstream (GXW-4024) had major issues with Fax, so we only use them for connecting for voice only applications. They seem to work well with Asterisk, and are easy to configure. Don't count on fax working at all though, or even worse working in some cases... AudioCodes is where we finally found a product that does what we need. They are about twice as much as a Grandstream (at least for the MP-124 vs GXW-4024) but have been rock solid for faxing so far. They also come in multiple configurations which is handy. We use the MP-114 2FXS/2FXO device at our remote sites for local PSTN access and to connect a fax machine. They also support survivability (proxy registration) in case of WAN failure. The complaints that I have are that the web interface has A LOT going on, and there is no real CLI to speak of. Neither of these are real issues, just takes you a few more minutes up front to read the manual. I haven't tried any Adtran devices but have thought about purchasing one to test with if I ever get the time. -Jonathan
