Description

Cisco Unified Communications Manager (CUCM) multisite deployments can use various connection options between sites. Multisite dial plans have to address special issues, such as overlapping and nonconsecutive directory numbers, public switched telephone network (PSTN) access, PSTN backup, and tail- end hop-off (TEHO). This course describes multisite deployment connection options and explains how to configure them.
Also covered in this course is how to build multisite dial plans using CUCM and Cisco IOS gateway configuration. The concept of globalized call routing – a new way of building dial plans in international multisite deployments is also discussed.
