Software Features
Customization & Simple Environment
The ApexVoice SIP GSM gateway works on Windows 10 (64-bit, English version), minimum spec: i3 CPU, 4GB RAM, 5GB free space.
Easy to Use
Very user-friendly. Connect phones to the USB hub, run the software, and manage everything from the GUI. No coding required.
Termination / Origination
Supports GSM call termination, origination, DID numbers, SIP to Telegram, and SIP to WhatsApp termination.
Multiple Routing Algorithms
Route calls based on channel ACD, ASR, channel load, or sequentially.
SIM Block Protection
Phones operate like normal devices (not gateways), reducing SIM detection. Includes block guard module, voice captcha, human-like delays, load balancing, and number filtering.
Callback Route
Acts as an answering machine if agents are unavailable — stores recorded audio messages for follow-up.
Channel Usage Control
Set limits on call count or duration per channel. Once exceeded, that channel stops receiving calls.
Dialing Plans
Assign prefixes to specific channels. Handle multiple network traffic types at the same time with different SIMs.
USSD and SMS Support
Check balances, recharge, send and receive SMS from software.
Whitelist and Blacklist
Use blacklists to block numbers or whitelists to allow only specific numbers.
SMPP Protocol Support
Terminate SMS alongside calls. Support for long messages, multiple languages, TLS, and SMPP keepalive.
Security
Enable SIP and RTP encryption via settings.
Call Recording
Record all calls (inbound and outbound) as MP3 files on your PC.
