We have the free version of 2 calls per minute.
10 calls per minute: US $ 250.00
20 calls per minute: US $ 400.00
30 calls per minute: US $ 500.00
60 calls per minute: US $ 750.00
Calls per mminute means that the program will have the ability to send that number of calls every minute. If the message delays more than a minute there is a risk of saturating the PBX channels.
