Avotus alternative
Avotus is a full ECM/TEM platform. Teams look for alternatives when the immediate need is call accounting and chargeback not an entire suite rollout.


TL;DR:
eXsight is one alternative for multi-vendor call accounting and chargeback delivered by entrypoint. Also evaluate AMI Strategic, Valcom, and carrier TEM vendors (Tangoe, Calero) based on whether invoice or CDR data is primary.
