## Brazil signs call authentication rule
Brazil's President Luiz Inácio Lula da Silva signed a provisional measure forcing phone carriers to authenticate calls on their networks.
## 15-day call blocks for mass callers
Lines making over 1,000 short calls daily can be blocked for 15 days if 85% of calls are short.
## Threshold for call blocking
A user must place more than 1,000 calls from one line or 10,000 across all lines within a day.
## Short calls definition
Short calls are those not completed, sent to voicemail, or six seconds or less.
## National phone number database
Carriers must create a national database listing phone number holders and business details.
## Anatel's 60-day deadline
Anatel has 60 days to issue detailed rules for call authentication and blocking.
## 30-day enforcement period
The per-line call limit becomes enforceable after 30 days from publication.
## US companies affected
US companies using Brazilian numbers need to display business names in the national database.
## What's not known
The measure gives no figures on scam calls or how many lines would meet blocking criteria.
## What comes next
Congress must approve the measure within 60 days for it to become permanent law.
## Key takeaway

Brazil requires phone carriers to authenticate calls and block lines making over 1,000 short calls daily for 15 days to curb phone scams.
