Dear all,

I am working to develop an IVR solution for an NGO in Tamil Nadu, India
using Freeswitch open source telephony interface.

I am looking for any cost effective solution for hardware where concurrent
inbound/outbound calls can be made by the IVR system. Some research, I did
but I am skeptical, need some more guidance from experts. Number of
concurrent calls for initial stage inbound 5-10 but based on response from
the community, we will plan for scaling up. Outbound Scheduled calls are of
lesser importance right now.

I checked online that PRI line provides me 30 lines for voice which can be
used concurrently. But, the rent for the line is very high which cant be
feasible for the NGO.
Min PRI line cost is Rs 4.5 K per month.

Please suggest alternative solutions which I can use for the same.

1. What about VOIP  and using their local access number?
2. What about SIP based IP phone with extensions?
3. What about trunk lines, DID etc?
4. What about GSM Modems, GSMOpen?

I am very new telecom technology. Please help.
