Abstract: Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems.

独立电话系统通过使用来自两个系统的对称分叉而被整合。 任何一个系统收到的呼叫都被分到另一个系统。 因此，一个呼叫可被其中一个系统接受，使用其外部接口，并被呈现给两个系统中的所有设备。 每个系统都可以利用内部呼叫控制高级功能来增强整体用户体验。 在两个系统之间使用内部插入的调用请求参数来防止集成系统之间的无限循环呼叫。

Abstract: Systems, methods and computer program products for facilitating the recovery of lost real-time media packets within a computer network real-time application implementing Forward Error Control (FEC), such that server performance is not affected from a CPU and memory perspective, are disclosed. In an embodiment, a conference server that is part of a communication network compliant with the Real Time Transport Protocol (RTP) is able to avoid regenerating FEC packets by not performing any FEC coding operation on the packets unless it is flagged to indicate regeneration via an FEC (e.g., Reed-Solomon) coding is necessary. Absent the flag, the conference server updates the received FEC packet as per the RTP and transmits the packet to its ultimate destination. Such disclosed systems, methods and computer program products are independent of the nature of the media being protected and flexible enough to support a wide variety of FEC techniques.
