To connect PSTN to Asterisk, you need

an amphenol cable:

A break out box:

and a TDM24xx Card like the one below. But instead, load it up with FXO modules.

Many in the industry use Audio Codes gateways.

Unless I am missing something, that doesn't have 24 x FXO. Did I miss something? Or would you need 6 of them?

Are You Ready for GDPR?

With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

yeah,i'm looking for gateway/media gateway like mediant not card/pci module for asterisk because i don't want to install driver or compile its kernel .

But mediant is too much expensive! can you suggest other brand name?
(p.s: i need this device to connect pstn to asterisk for calling card access number )

JRSCGI has given you the right device.

You are typically not going to find something much cheaper because you need 24 FXOs, and I wouldn't recommend the cheaper ones anyway.
