简介

本文描述与代理不会获得Cisco Unified Presence信息的注册的客户端的一编解码器问题。

贡献用Kristof范Coillie, Cisco TAC工程师。

问题

当movi客户端是在思科网真视频通信服务器(VC)时高速公路注册的代理对VC控制统一的Pesence,关于其他用户的信息不是可用的在此客户端。

解决方案

默认行为

当全球可发送的用户代理统一的资源标识符(URIs)时(GRUU)模式是默认设置,您在VC控制的注册过程能看到客户端和服务器公布GRUU的支持:

VC控制发送此通知消息到VC高速公路;除非域名服务器(DNS)区域在VC高速公路配置用IP地址替换域,消息不会到达客户端。

当有解决域配置时的DNS区,这通知消息被退还的到VC控制哪些反过来送回它到VC高速公路和终于对导致很多开销的客户端。

解决方案

使用此命令,对VC控制统一的在线状态问题的解决方案将禁用在VC控制的GRUU,这应该执行在集群的所有对等体:

xConfiguration SIP GRUU Mode: Off

关于全球可发送的用户代理URIs的更多信息参考的RFC 5627

 

行为同被关闭的GRUU模式

当GRUU被关闭时,您能看到在服务器不添加GRUU的支持的注册步骤的差异:
