openh323 通用库 -Universal library for openh323

It s an introduction to the most popular opensource calling card platform.Its is fair to say that A2Billing when combined with Asterisk is is now a full featured telecom platform

如何成功的运用OPENH323 来开发商业的H.323 协议栈 Openh323 有以下的特征： 1>动态的静音检测算法, 以减小语音包的传输量。 2>支持Windows，Linux 和FreeBSD 的多种客户端命令。 3>包含有MCU，PSTN 网关，和自动语音应答机等多种应用平台。 4>软件支持GSM，LPC-10，G.711 uLaw/Alaw 软件编解码方式。 5>特定硬件（Quicknet/LineXJ）支持G.723.1, G.728 和 G.729 。 6>采用Jitter Buffer 技术对语音信号做接受的缓冲处理。 7>软件产生舒适噪音。 8>采用H.261 视频压缩协议。 9>支持广播的方式查找网守（GateKeeper）。 10>支持H.235 附件D 中和网守的身份认证。(部分地支持H.235) 11>支持部分H.450 补充协议。-How successful the use of OpenH323 to develop commercial H.323
