ENSURING HIGH-AVAILABILITY IP COMMUNICATIONS IN BUSINESS READY BRANCH AND SMALL OFFICES
As enterprises extend their IP telephony deployments from central sites to remote offices, one vital consideration is whether backup redundancy can be provided cost effectively at small branch offices. The size and number of these small offices precludes most enterprises from deploying dedicated call-processing servers, unified messaging servers, or multiple WAN links to each site to achieve the high availability necessary. Additionally, small offices do not generally have expert IT personnel. Therefore, any solution must be simple to deploy, administer, and maintain.
