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.

The dual-channel wireless device may also comprise a second transceiver operative to communicate voice information over a voice channel using a circuit-switched network during the session. Other embodiments are described and claimed.

Abstract: A method of preparing metal mesoporphyrin compounds is described. A metal mesoporphyrin compound may be formed by forming a novel mesoporphyrin IX intermediate compound and then converting the mesoporphyrin IX intermediate to a metal mesoporphyrin compound through metal insertion. The novel intermediate compound may be formed by a catalytic hydrogenation of hemin in acid and subsequent recovery.

Abstract: Providing non-voice capabilities relating to a phone call at a computing device includes receiving a request to begin a telephone call from a first telephone to a second telephone, wherein the requesting is performed using messaging between computing devices connected via a computer network, and wherein the messaging is part of a signaling phase dialog. The signaling phase dialog may be used in providing information associated with the identity of parties of the telephone call. Commencing a call phase dialog between the computing devices may be performed after the telephone call is established over the public switched telephone network. The call phase dialog may allow messages relating to the telephone call to be passed between the computing devices, at least while the telephone call is in progress. The dialogs and messaging may be performed using session initiation protocol (SIP) or another computer communication protocol.

Abstract: Techniques for associating one or more real-time sessions, which are each signaled separately, into one logical conversation without a centralized control, are provided. Some techniques share a conversation identifier that uniquely identifies a logical conversation across the real-time sessions that belong to the logical conversation. The conversation identifier is generated before the first real-time session belonging to the logical conversation is signaled, and distributed to the other participants in the logical conversation via the signaling channel. A called participant can use the conversation identifier for associating the previous real-time sessions belonging to the logical conversation, and for making new invitations for other real-time sessions that are associated with the same logical conversation.

Abstract: Concurrent calls are multiplexed over packet network connections such as TCP/UDP/IP connections. Initially, semi-permanent, open channels (e.g., TCP and/or UDP channels) are established between two or more packet switches. The switches format incoming calls, as necessary, and multiplex them onto the open channels. Identifiers may be added to the multiplexed calls to facilitate the demultiplexing of the calls by the receiving switch. The multiplexed calls are encapsulated into packet network protocol packets (e.g., TCP/IP or UDP/IP) for routing over a packet-based network (e.g., IP).

Abstract translation: 并发呼叫通过分组网络连接进行复用，例如TCP / UDP / IP连接。 最初，在两个或更多个分组交换机之间建立半永久的，开放的信道（例如，TCP和/或UDP信道）。 交换机根据需要格式化来电，并将其复用到打开的频道上。 可以将标识符添加到多路复用呼叫中，以便于接收交换机对呼叫进行解复用。 复用呼叫被封装成分组网络协议分组（例如，TCP / IP或UDP / IP），用于通过基于分组的网络（例如，IP）进行路由。
