Call Blocking
Stop spam and robocalls before they reach your team.
Block unwanted callers by number, pattern, or caller ID type. Blocked calls never ring a phone — your team never even knows they happened.
Trusted by 1,000+ Canadian businesses · 5,000+ users
92% of consumers believe unidentified calls are fraudulent — and your team wastes time on them too. EMAK's blocking rules run at the system level, so unwanted calls are stopped before they ever ring.
Included in every plan — from $20// extension / month.
Defense at the system level.
Spam and robocalls don't just waste time — they disrupt focus, tie up phone lines, and can even spoof legitimate numbers. EMAK's blocking rules run at the system level, so unwanted calls are stopped before they ever ring.
Per-user and system-wide rules. Emergency numbers always bypass blocking — so 911 always gets through.

Silent drop
Drop the call with no signal at all. Spammers can't tell if the number is valid, so they're less likely to try again.

Frequently asked questions.
How do I block spam calls on my business phone?
In the EMAK portal, create a call blocking rule by number, pattern, or caller ID type (e.g., block all anonymous callers). Rules take effect immediately across your VoIP system — blocked calls never ring a phone.
Can I block an entire area code?
Yes. EMAK supports pattern-based blocking. Enter an area code prefix and every call from that range is blocked automatically.
Do blocked callers know they're blocked?
That depends on your configuration. You can reject with a busy tone, play a custom message, send to voicemail, or silently drop the call. You control what blocked callers hear.
Can I block anonymous or withheld numbers?
Yes. Create a rule that blocks all calls with no caller ID or withheld numbers. This is one of the most effective filters for spam — legitimate business callers almost always send caller ID.
Does call blocking cost extra?
No. Call blocking is included with every EMAK business phone plan at no additional charge, along with all 40+ features.
