Questions, answered.
Why does SIM calling achieve much higher answer rates than cloud PBX?
Cloud telephony vendors like Exotel and Knowlarity use virtual 080 numbers or recycled landline pools that consumers and Truecaller automatically flag as promotional spam. Real 10-digit mobile SIM cards signal genuine human communication.
Can sales reps make calls when offline?
Yes! AI Closer features an offline-first SQLite/Room event store. Telecallers in poor connectivity areas can dial prospects and record outcomes, and all logs sync automatically when internet restores.
Does AI Closer record personal calls made by employees?
No. AI Closer specifically logs and synchronizes business sales leads assigned in the CRM workspace, safeguarding personal employee privacy.
