Want to develop a PBX based on SIP. Ordinary functionality needed, such as autoattendence, forwarding and so on.
Use of GNU components is alright.
Experience from earlier SIP development is a plus (if not a requirement).
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased.
Linux or Windows.
