- Flexible Call Control: Define call flows in your own application logic, including how calls are initiated, answered, ended, and handled across multiple participants.
- Direct Calls to Hunt Groups: Route incoming calls to hunt groups using the members and call distribution method defined in your application.
- Place in Queue: Put incoming calls in a queue, play prompts, and redirect them as needed, which helps manage callers when nobody can answer immediately.
- Parallel Ringing: Ring multiple employees at the same time and stop the other phones once someone answers, reducing the chance of an incoming call being missed.
- Voicemails & Auto Attendants: Send calls to voicemail or automated attendants according to your application logic.
- Record and Play Prompts: Record audio prompts and play them within call flows such as IVR, so callers can receive instructions or menu options.
- Mobile Extension (MEX): Bring cloud-PBX call control to mobile users and use common logic for mobile and fixed telephony.
- Comprehensive APIs: Use the SIP Mediaserver Service APIs and REST callbacks to connect PBX call handling with your application, giving developers detailed control without building the underlying telecom functions themselves.
- Unlimited Scalability: The serverless backend automatically scales cloud-PBX services up or down as demand changes, without adding and configuring new hardware.

Pros
| Competitor | Pros |
|---|---|
| Kamailio | Iotcomms Cloud-PBX Solution runs the SIP and media-server functions as managed cloud services, while Kamailio is open-source SIP server software that users deploy and operate themselves. Teams that want PBX call control without maintaining SIP infrastructure may have less operational work with Iotcomms. |
| Sinch | Cloud-PBX logic is a specific focus for Iotcomms Cloud-PBX Solution, with APIs for hunt groups, queues, parallel ringing, voicemail and mobile extensions. Sinch offers programmable voice too, but its SIP Trunking product mainly connects an existing PBX or SIP system to its voice network. |
| Infobip | Iotcomms Cloud-PBX Solution lets the customer application hold call state while its SIP Mediaserver Service executes call control through REST callbacks. Infobip’s SIP Trunking documentation instead starts from connecting an existing PBX or SBC, so Iotcomms is more directly structured as a backend for building the PBX itself. |
Cons
| Competitor | Cons |
|---|---|
| Kamailio | Kamailio is GPL-licensed open-source software with routing, load balancing, registrar, WebRTC and other SIP functions, and it can handle thousands of call setups per second. A team that wants full control of its own SIP stack and infrastructure may prefer that model over Iotcomms Cloud-PBX Solution’s managed SaaS approach. |
| Sinch | Sinch combines Voice APIs with Elastic SIP Trunking and a network spanning 60+ countries, including direct PSTN access and global number services. Buyers who need carrier connectivity and PBX interconnection from the same provider may find Sinch broader in that part of the stack than Iotcomms Cloud-PBX Solution. |
| Infobip | Infobip supports SIP trunks plus programmable Calls APIs across PSTN, SIP and WebRTC, with connectivity described across more than 200 countries. For a buyer whose main need is global telephony access alongside programmable call applications, Infobip packages those network and API capabilities together. |
