[asterisk-users] Reverse-ATA : Using PSTN lines to connect toAsterisk

[Mike]

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.

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
