We need a Basic SIP client and should be written in VB.NET, should have a front end written in WPF, and requires the following features and source code:
IAX Protocol Support
STUN server Support
Local Signalization (Dial tone, busy, ring back, etc.) for user comfort
Microphone Volume Control
Speaker Volume Control
Works well on most of the versions of Microsoft Windows ( NT4, 2000,XP, 2003, Vista, Win 7)Versions
Auto-configuration of settings for easy deployment
The appliction should be designed with a data access class, a services class, and a WPF GUI. The functionality of this control may be called from other modules and therefore the GUI must be decoupled from the services class. If you don't know what this means then please do not place a bid. Please PM me if you bid and put asterisk somewhere in your PM so I know you are not a bot.
We will be using a .NET SIP component for this application, so there is no requirement for the winning bidder to code everything from scratch. This should be a fairly easy project since you will be using someone else's SIP API.
Note: You should provide a demo with above mentioned features.
