FREQUENTLY ASKED QUESTIONS (FAQ's)

Find answers to common questions about TeleOSS SMS Gateway Software

What is TeleOSS SMS Gateway Software used for?

It is used to send, receive, route, and manage high-volume SMS traffic including OTP, transactional, and bulk messaging for enterprises and aggregators.

Which protocols does the SMS Gateway support?

The platform supports an HTTP SMS API and SMPP protocol for enterprise applications and carrier-level integrations.

Does it support two-way SMS (MO/MT)?

Yes, TeleOSS supports both Mobile Originated (MO) and Mobile Terminated (MT) SMS with real-time handling.

What is an SMS gateway API?

An SMS gateway API is the SMPP or HTTP interface that lets your application send, receive, and track SMS traffic programmatically. TeleOSS provides both, with full documentation for enterprise and aggregator integrations.

What is dynamic routing and how does it work?

Dynamic routing selects the best delivery path for each message in real time based on cost, delivery performance, and route health, instead of sending traffic down a single fixed route. TeleOSS recalculates this continuously and fails over automatically when a route degrades.

Yes. TeleOSS handles high-volume bulk SMS campaigns alongside transactional and OTP traffic, with the same routing, DLR, and billing controls across all message types.

Yes, it is optimized for time-critical OTP SMS and transactional messaging with high delivery success rates.

Can I use it as a white label SMS gateway?

Yes, the software supports white label deployment with custom branding and reseller management.
