Does anyone know of an VoIP FXS port other than the one for Raspberry PI:

The pricing looks unfavorable, compared to outboard dedicate units. I see this at Amazon with minimal searching -- FXS and FXO combo listed

Grandstream HT-502 Dual Port FXS Gateway $37.50

GrandStream HT503 1-FXS/1-FXO Port Analog Telephone $54.26

Grandstream GS-HT702 Handytone 2-FXS Port Analog Telephone Adapter $34.31
