@eludom @SDF @jasmaz Sure! The key things here are 1) a DD-WRT router in WiFi client mode and 2) a unlocked pulse dial capable ATA. Here I am using an Innomedia MTA 6328-2Re but the very common Linksys RTP300 could do it too with v1 firmware. RTP300 unlocking depends a lot on initial version so you need to be careful. Probably buying a RTP300-NA (unlocked) before firmware downgrading would be preferable.
