Using H.450.x Tandem IP-to-IP Gateway

Summary

In this chapter, you've learned how to connect a network of Cisco CME systems with a Cisco CallManager using H.323. You've seen how Cisco CME can automatically and intelligently react to the presence of a Cisco CallManager and adapt its behavior accordingly. You've also learned how to optimize call transfers and forwards using H.450 for intersite Cisco CME calls within a fully distributed telephony network that at the same time can interoperate with a central site Cisco CallManager.
