I've been using Nomorobo for several years now, and generally, I'm really happy with it. However, with the number of calls being caught daily by it, even the single ring is a bit annoying. Is there a setting within the ATA (Grandstream HT-502) issued by Voipo to delay ringing for a second or two to allow for Nomorobo to catch the calls before the phones ring?

Thanks very much!
