Hi,

We have a requirement to build a prepaid system using OpenSER. I took a look at CDRTool which looks quite promising. But I am not sure how to build the Call control module and provide IVR type information to the end users.

If any one has done similar type of job, please respond.

thanks,

Rana

You should look into asterisk for the IVR and probably the ability to terminate calls (openser only sets up the sessions). SipX might be another option also.
