Convert a PSTN to VoIP to PSTN

[Alan Daniel Chavira Rodriguez]

I have  4 PSTN lines, i want to put them over ip and send via wireless to a branch office and there I want to convert from IP to PSTN again to connect a PBX.

Can i use a Cisco SPA8800 o SPA3201 to do this?

Or how can i resolve the problem, somebody who can help me...

Thanks

It is normally done, however if you are the end user, it is recommended you engage a professional for the task.

There are too many confusing thing that could and will go wrong unless you belong to the trade.
