Freeswitch with astpp - consultancy needed

Hi all,

We are exploring the opportunity of hosting a FreeSWITCH + astpp solution in order to create a hosted softswitch product. No calling cards, only select voip Servers will be working as clients on this server. so
1)IP-to-IP authentication,
2) per seconds billing.
3) large number of concurrent calls (500 above, usually it is 1000+)
4) the client (voip servers) whould able to access their dedicated CDR link
5) softswitch admin should be able to manage funds per client
6) multiple providers should be supported.

Please let me know if some one can carry out this project. contact me at voipgcc at gmail dot com

Regards

Sherly davis
