# Digital and Analog Voice Interworking Overview

VComp bundles solve the following interoperability requirements:

- Interoperability between digital and analog voice channels. For example, when remote sites use analog trunks and the central site voice switch location uses digital T1/E1 connections. In this case, you can use VComp bundles to aggregate the analog sites into higher-density digital interfaces on the central voice switch.
- Interoperability between sites inside and outside the United States. Generally, mu-law companding is used inside the United States and a-law companding is used in Europe and elsewhere. You can use mu-law to a-law conversion between E1 and T1 voice interfaces to connect these sites.
