Frequently asked questions
Evaluation essentials.
Do we need to replace our existing PBX?
Not when the current system is compatible and still meets operational requirements. Compatibility is confirmed during assessment.
Can we keep our existing phone numbers?
Number portability depends on the numbers and current carrier. Teliance reviews availability before a migration is scheduled.
How is required capacity determined?
Capacity is based primarily on expected simultaneous calls, location design, and continuity requirements.
