Frequently asked questions
Aren’t all SIP trunks already IP-based, and how are they different in practice?
While traditional SIP trunks use IP, they still terminate on physical lines connected to a PBX or call server. This requires hardware, long provisioning cycles, and added operational effort. Cloud SIP trunks remove physical termination, enabling faster setup and simpler operations.
How is Exotel’s Smart Cloud SIP Trunk different from a regular SIP trunk used by businesses today?
Unlike regular SIP trunks that terminate on physical lines, Exotel’s Smart Cloud SIP Trunk delivers PSTN connectivity over IP networks like the Internet or MPLS, eliminating on-prem cabling, local data center hardware.
Who can benefit the most from using Smart SIP Trunks for modern voice communication needs?
Any organization looking to enable voice across PSTN, OTT or digital voice, and app-to-app channels can benefit. Smart SIP Trunks remove physical infrastructure, reduce maintenance costs, accelerate deployments, and simplify communication spend through a scalable, recurring model governed by a single SLA.
What additional capabilities does Smart SIP enable for modern, distributed work environments?
Beyond basic calling, Smart SIP enables IVR, call recording, AI summarization, sentiment analysis, branded calling, reporting, and performance analytics. It delivers a consistent, secure voice experience across PSTN, digital voice, and app-to-app channels for both customers and employees.
What do you get with Smart SIP Trunks beyond basic PSTN calling capabilities?
Smart SIP Trunks deliver PSTN over internet or MPLS without physical infrastructure, offer multi-operator fallback for high reliability, and support IVR, recording, AI summaries, sentiment analysis, and reports for modern enterprises.
