Question 1

What is STIR/SHAKEN and why does it matter for outbound calls?

Accepted Answer

STIR/SHAKEN is a carrier-level call authentication standard. Calls that pass STIR/SHAKEN verification are less likely to be flagged as spam and more likely to be answered, which improves pickup rates significantly.

Question 2

Can I show my business name on outbound calls?

Accepted Answer

Yes. Branded Call ID allows you to display your business name (not just a number) on the recipient's caller ID, subject to carrier support. This significantly increases answer rates.

Question 3

Will my numbers be flagged as spam if I run high-volume outbound campaigns?

Accepted Answer

Grezorea monitors number reputation in real time and rotates numbers before they accumulate spam flags. Our infrastructure is designed for high-volume outbound while maintaining deliverability.

Question 4

Can I use my existing business phone numbers?

Accepted Answer

Yes. You can port your existing numbers to Grezorea, or use your numbers as the caller ID while routing calls through our infrastructure.
