I'm considering the SPA2102-NA Voice Gateway to replace my Ooma Telo (and subscribe to a new VOIP provider also) after getting burned by the fact that the Ooma Telo and/or Ooma VOIP service will not support inbound DTMF. Because of this deficiency, I am unable to control my alarm system and answering machine remotely. Can anyone advise if the SPA2102-NA Voice Gateway will properly support inbound DTMF? I am unable to find the answer in the documentation I have read.
