Traditional Phone Systems Can't Keep Up
SIP Trunking lets you move away from traditional ISDN or PSTN lines by routing voice calls over your existing internet connection. It’s a smarter, leaner way to run your business phone system, without changing your existing PBX hardware.
With AOIT’s Managed SIP Trunking, you gain a reliable, enterprise-grade voice service tailored to your specific call volume, coverage, and growth goals. Whether you’re looking to reduce call costs, improve call quality, or prepare for the PSTN switch-off, we make the transition seamless.
Legacy phone systems are not only expensive, they’re holding you back. With the PSTN network being phased out, businesses still reliant on traditional lines face rising costs, limited flexibility, and mounting compatibility issues.
Without SIP Trunking, you risk:
- Cost inefficiencies, from high rental charges and long-distance rates
- Scalability issues, where adding lines is slow and restrictive
- Downtime vulnerability, due to lack of built-in failover
- Regulatory pressure, as the PSTN switch-off deadline approaches
AOIT’s SIP Trunking service ensures you’re ready for the future of voice, securely, affordably, and without disruption.
