Independent support for existing A2Billing installations. Fennix Global helps telecom operators, VoIP providers and call-centre platforms troubleshoot and maintain business-critical A2Billing and Asterisk environments. We focus on restoring service, getting billing right and making careful, documented changes rather than replacing a working platform without a clear business reason.
Practical A2Billing expertise for live telecom operations
- Billing and tariffs: ratecards, prefixes, rating accuracy, customer balances, CDR reconciliation and upstream cost analysis.
- SIP and routing: Asterisk, trunks, dialplans, AGI, provider interoperability, call routing and failover diagnosis.
- Break-fix and recovery: failed services, connectivity, configuration faults, database issues, backup review and restoration planning.
- Legacy system health: security exposure assessment, restricted access, monitoring, backup strategy and operational documentation.
- Migration planning: assess whether maintaining or replacing an existing deployment is the lower-risk commercial choice.
