Grandstream make a 4-port and an 8-port FXO ATA
Linksys make one but I think it is proprietary to their own "Linksys One" system

Probably, if I only needed one FXO. What is the customer has 4 "channels" (PSTN lines)? Don't I need 4 FXO? And, about the Sipura, it looks like it would do what I want, but it only has one FXO, limiting it's usefulness. Mike On 4/10/07, *Mike* <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> wrote:

    Hi,
I'm looking for a few pointers on using ATA to connect Asterisk to
    the PSTN.  Basically, I'm running a Hosted PBX service, and in
    urban centers I can usually get SIP or PRIs.  Since I sell my
    customers SIP hardphones, the data flow is like this:
Customer's SIP Hardphone ---- My own Asterisk ----- Outside lines But when it comes to smaller villages (I deal with people in tiny
    places), I'd like to reuse their own PSTN line this way:
Customer's SIP hardphone ---- My own Asterisk ------ Some device
    on the customer's premise ---- customer's PSTN lines
I know ATAs are mostly used in a scenario where you reuse
    traditional phones to connect to SIP servers, but can they
    accomodate my scenario? And if so, what line of ATA should I be
    looking at?
Mike


Hello Mike,

Wouldn't a Sipura SPA 3000, with an FXS and an FXO, handle what you want?

Cheers,

Francis
