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

I see a trouble giving the caller IVR over VOIP.

Noname is right. You can NOT do that with just a gatekeeper. In that case you need a combination of softswitch with calling card + IVR system.

Such one is AlterPSS (russian made).
It has a client softhpone, calling card system + IVR via IP, softswitch… All in one. Except the billing.
