IPTT v Summary There are four common areas for troubleshooting Cisco voice networks: Cisco CallManager, Cisco Unity, network infrastructure, and voice clients. Cisco CallManager is typically the first place to look for problems when troubleshooting common VoIP issues. Cisco Unity is a common troubleshooting source because of its advanced configuration. The network infrastructure can be a common source of troubleshooting because it supports both the voice network and the data network. Incorrect configuration of voice clients can be a common troubleshooting source.
