How to block incoming phone numbers - HT-701 / HT-702

[neptune]

Hi everyone,

Is there a way to block incoming calls from certain numbers on Grandstream HT-701 / HT-702?
I've been using FPL for a couple of years but never looked into this. The last few weeks have been annoying due to late night calls from marketers, overseas callers, etc.

Thanks very much!

I've tried searching online and on Grandstream's site as well... can't seem to find anything helpful....

Hi, did you put your ATA in DMZ recently? tons of scanner software will call your phone if so.

No, ATA is not in DMZ.
