FireRTC SIP Failure

When I am calling scammers with numbers we all post FireRTC always has a SIP Failure. I know what it is but I just don’t know why it is happening. These are fairly new numbers.

Thanks,
Jack

Use TextNow online, or FreeTone for an iPhone. If you don’t want to use either of those use Globfone.com or Zlookup.com.

Getting the same tbh.
