iPhone app - SIP Softphone Client

We need a developer to write an iPhone Application for us.

The app needs to be able to perform basic telephony functions such as:

-Registering to a SIP/IAX Server

-Answering calls

-Dialing a number and establish a PSTN call

-Dialing a username and establishing a SIP call

-Put user on hold and streaming on hold music

-Have 2 lines (where once a call has been established can merge)

-Call conferencing while the user is on a call

-Changing presence status, i.e. available, away, do not disturb

-Connecting to 2-3 SIP servers at once

-Showing caller display while connected

-Having the ability to add and configure SIP/IAX account settings within the app

This purpose of the app is to develop the core code that performs the SIP/AIX communications. We would NOT like to use open source code for the SIP core functionalities.

We require a developer who has worked with SIP/IAX for iPhone and has proof. Once you can demonstrate this, then we will discuss talks further.

Similar apps are Telephone for Mac OSX, X-Lite for PCs.

Skills: Cocoa, iPhone, Mobile App Development, Objective C, VoIP
