Linux 构建功能强大的voip网络电话服务器

centos5.4下建立一个属于自己的功能强大的VOIP网络电话系统

环境：
centos 5.4
asterisk 1.6.1.9
freePBX 2.6.0RC2

现如今经过几年的信息化建设，IP网络已经走进绝大部分大型企业，多数企业内部均已经建立了内部数据网络。并且实现与INTERNET网互联。在基 础网络建设完成以后，为更好的利用现有的IP网络资源，提高企业信息化水平和办公自动化水平，节省语音通话费用，在企业内实现语音数据的统一传输，紧跟下 一步电信发展的潮流和趋势，建立基于IP网络的数据语音综合服务将是企业大客户在信息化建设、提高综合竞争能力等方面需要着重考虑问题。
