VoIP technology is one of the fastest growing technologies today. It is used for voice communication over the Internet with high quality sound and due to its wide penetration it is supported by many devices. However many mobile service providers block the usage of the port 5060, which is used for SIP protocol. (SIP protocol is used in VoIP communications). This means that many mobile service providers block the usage of VoIP on your mobile phones. I have come up with a solution for this problem. It is a WP7 client application that communicates with a server through TCP/UDP protocol and the server communicates with a PBX through SIP protocol. This way the mobile service providers will not block the VoIP communication because they will only see the TCP/UDP communication between the client and the server.
