VOIP VS. PSTNCOMPARISON
VoIP transmits voice as data packets over your internet connection. PSTN uses dedicated circuit-switched copper lines. PTG helps businesses understand the trade-offs and migrate to the right solution.

Comparison Questions
Is VoIP reliable enough to replace PSTN?
Yes. With adequate bandwidth, QoS configuration, and failover planning, VoIP delivers enterprise-grade reliability. PTG designs redundancy into every deployment.
What about power outages?
VoIP requires power and internet. PTG mitigates this with UPS battery backup, cellular failover, and automatic call forwarding to mobile devices during outages.
Should every business switch to VoIP?
Most businesses benefit from VoIP. PTG evaluates your specific situation including internet reliability, compliance needs, and existing infrastructure before recommending a migration.
Can we use both VoIP and PSTN together?
Yes. A VoIP gateway allows both technologies to coexist, which is useful during phased migrations or for analog devices like fax machines.
