The combination has worked extremely well for me.<br>

<br>
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. <br>
<br>
If any one has done similar type of job, please respond.<br>
<br>
thanks,<br>
