Chapter 7. Implementing Cisco Unified Communications Manager Express (CUCME) in SRST Mode

Cisco Unified Communications Manager Express (CUCME) has many features, benefits, and limitations compared to CUCM. This chapter explains those features and the process of registering IP Phones with CUCME for Survivable Remote Site Telephony (SRST). This chapter also discusses the basic telephony-service commands for configuring ephones and ephone-dns.

You will be able to meet these objectives:
