Abstract
A network telephone system for recovering talk after an unexpected disconnection and a method thereof are used to recover an unexpectedly disconnected talk between network telephones. The network telephone system includes a central processing unit, a talk database, a real-time transport protocol (RTP) buffer, and a network module. A method for recovering talk after an unexpected disconnection includes: recording and storing information of the network telephone in a talk state; judging whether an unexpected disconnection of talk occurs by checking that the network is disconnected or no RTP packet exists; and re-establishing talk by inquiring the network telephone information of a current talk.
