Abstract

System and method of forwarding a call request initially directed to a regular phone to a VoIP system to avoid call roaming. A callee's regular phone is configured for call forwarding to the VoIP system by linking the phone number with a local access number of a Session Initiation Protocol (SIP) platform of the VoIP system. Any call request directed to the phone number is automatically forwarded to the SIP platform through the local access number and converted to a VoIP call request. If the VoIP user account of the callee is online, the SIP platform initiates a VoIP communication session. Thus, even when the regular phone is located in a roaming region, the VoIP system takes over the call request such that no roaming charge is imposed to the callee.
