Hello, and thank you for your answer. Do you have some suggestion for following case ?
I have some Call shops ( devices will be voip phones connected to a AS5300 via leased line)
So i will have to manage the following option
1) voip >> As5300 >> pstn ( for local calls)
2) voip >> ISP (Go2Call) for Long Distance Calls
Some phones will work in POSTPAID mode ( so when customer pickupthe phone, he will hear dialton)
Others phone will work in PrePaid mode , so the customer will hear IVR instructions).
All calls ( Pre and Post , will be processed by AdvancedVoip Billing System)
Thank you for your attention
