此方案导致，当SIP乙肝是启用的时，并且太积极地设置乙肝超时。此方案普通，当Cisco Unified SIP代理(尖顶)或SIP网关交叉不可靠的广域网。
解决方案
修改此键，最好是HBNumTries，为了适应广域网性能。
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\cicm\Dialer
HBNumTries and/or HBTimeout
为了确认网络是可靠的，请采取Wireshark捕获在两端。保证配置在Windows 2008服务器的拨号程序为了禁用卸载。接收端比例缩放和烟囱正如联系中心网络所描述：卸载，接收端比例缩放和烟囱条款。
