I have been using the Sipura/Linksys/Cisco SPA3102 for many years. This device, though still available from AliExpress for $25, has reached end of life many years ago.
What are good options for a single line FXO?
PS: My asterisk is running on a Pi, so I am looking for a standalone device.
The A4A PCI analog card supports up to four (4) connections per card in your Asterisk system. Using Digium’s single-port interface modules, the A4A card can scale from one (1) to four (4) ports. Optional hardware echo cancellation is available with the VPM032 module.https://store.digium.com/src/boards/#search/1A4A00F
Thanks, I forgot to mention that my asterisk is running on a Pi, so I am looking for a standalone device.
A one port reliable solution, I don’t know any, I use GXW4104 FXO (4 ports) the call quality very good and many handy features
