AAR呼叫搜索空间(CSS)是调用可在Cisco IP电话配置的行(目录号)级别应用的搜索空间的特殊应用。此博客将讨论自动备用路由(AAR)和AAR CSS的应用。AAR技术允许Cisco IP手机通过WAN通过WAN来电呼叫,以便在使用所配置的基于位置的位置的带宽时重新路由到公共交换电话网络(PSTN)。AAR假设以下配置和技术:•集中式呼叫处理•直接向内拨号(DID)•基于位置的呼叫入学控制(CAC)•外接电话号码掩码配置•AAR组配置•AAR调用搜索空间配置此博客的目的是此博客的目的与AAR CSS应用程序交谈,并非所有其他涉及AAR的组件。如果它感兴趣,我很乐意在AAR上写下随后的博客......让我知道。在PSTN上重新路由Cisco IP电话时,可能需要用于应用AAR的新CSS。使用缩写拨号计划实现正常的办公间拨号,但PSTN需要7,10或11位拨号。当调用设备的CSS限制要拨打的呼叫重新路由尝试时,AAR CSS是一个要求。有限的手机可能应该能够在PSTN上拨打电话,但只有在基于位置的CAC拒绝呼叫尝试时。 AAR CSS is not required in a distributed multi-cluster call processing model because inter-site call routing will use the route patter -> route list -> route group(s) -> trunk/gateway call routing logic. The route list is pointed to multiple route groups where different digital manipulation can be applied to the WAN_RG and PSTN_RG. If the WAN is not available, the PSTN route group normally prefixes the digits required to extend the call to the destination CUCM cluster. Centralized call processing models do not have this call routing logic. Calls in a centralized model are routed to destination IP addresses which may route calls to the next cubicle or across the world over a VPN tunnel. In the next blog, we’ll take a look at subscribe calling search spaces.
