OIGAA gives you everything you would normally be charged by your telephony equipment supplier and operator but for FREE. You save any charge for:

 

PBX investment or renting because OIGAA provides these features from the net
Telephony handset if you run OIGAA from the web
Fixed line rentals because OIGAA provides unlimited lines over Internet
Extension hardware or software charges because OIGAA provides unlimited ones
Upgrades or maintenance fees, because OIGAA upgrades automatically
Hardware extensions for unified messaging features and video calls
Dedicated hardware for call transfers to mobile
Call mobile cost from any dual-mode GSM/Wi-Fi mobile handset
Call cost per minute if you run OIGAA with an unlimited plan to 50 countries

 

OIGAA does not charge you for receiving calls on your mobile handsets while using ‘Call Back Dial’ feature. If you run a flat-rate mobile plan with favorite numbers with your operator, add your OIGAA local number into the plan and mobile operator didn’t charge you for those call-back calls anymore.
