Is it possible to make a sip gateway for an analog phone from a router?

Question

Asterisk

Good day, is it possible to make a sip gateway from a router with openwrt on board, for analog phones?

Answer 1

Doesn't make sense. The router does not have an FXS / FXO port, and its home-made implementation will cost more than purchasing a standard FXS / FXO gateway.

Answer 2

google -> openwrt asterisk
