Description: 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。
