We need the dialer exclusively configured with our softswitch IP for the patforms Symbian, iPhone, Android Dialer. The reason I am offering this project only to you, I know you have already completed a similar work. All which needs to be done is changing few paramerers from existing completed code. Secondly my budget is so tight that I have exausted myself for last 1 week to find a free or open source solution. In last I need it asap you can say even 1 or 2 days in an ideal scenario. Please offer me what is the cheapest you can offer.
