I am a Mechanical Engineer with a PhD in numerical modelling and a software architect with more than 10 years of experience. I also have a small telecom business. Customers are calling my SkypeIn (Online) numbers and I have an off-the-self, proprietary algorithm for detecting DTMF. The detection works very well when customers are calling from a landline. Problem arises when they are calling from a cellphone. Say the customer is entering 334550, the algorithm can sometimes recognise them as 333455550. The vendor of the algorithm is not available to help.

Can you help? What would you need? The system is coded in C# and I can record the audio in WAV files.

Please do state your background when placing your bid. If you don't, your bid will be ignored.
