Windows Mobile 5/6 Sip phone

We require a windows mobile dual mode phone for making calls over a Wifi or 3G network as well as GSM. Ideally the softphone would be an extension of the basic smart phone with the option to make a call from the contact book either over Wifi or the GSM network. A set of profile settings should be available which would select Wifi or GSM calls as a preference like the Nokia S60 range. Devices we are looking to support are the HTC S620 and equivalent PDA smart phone devices. We require STUN built in and the ability to select from a range of codecs including GSM, G729 & G711. Seperate profiles like, Home - Office - Hotspot should be available to select the WLAN bearer to make calls over. If this element can be handled in the Windows WLAN settings all the better. We need this quickly. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
