  Amanda RichardAug 11, 2025
  If you experience noise or static when speaking to people on your Aristel Telephone, or if they hear static, it could be due to a few reasons. It might be a network signal strength issue, or your VoIP carrier could be sending a low bandwidth voice stream. Try relocating the phone to see if the signal strength improves. Also, the antenna may not be installed correctly; check that it isn't cross-threaded and reinstall it.

  If your Aristel Telephone call does not connect after dialing, the issue might stem from several causes. First, there could be a network or signal problem, in which case you should try calling again; if the problem continues, restart the phone using the red button. Alternatively, your SIM or SIP carrier credit may be depleted, requiring you to recharge the SIM or contact the carrier. Finally, check if a SIM card pin code is enabled and either enter the code or disable it.

The Aristel Genius X2 is a 4G/SIP Desktop Phone designed for both cellular and Voice over IP (VoIP) communication, offering a versatile solution for various telecommunication needs. It supports 4G VoLTE/3G/2G cellular networks and can integrate with VoIP services, providing flexibility for users without traditional landlines or those seeking advanced communication features.

Function Description:

The Genius X2 serves as a primary communication device, capable of making and receiving calls over cellular networks (using a SIM card) or over the internet via VoIP (requiring a SIP account and internet connectivity). It can also function as a Wi-Fi access point (hotspot), allowing other devices like tablets and laptops to connect to the internet using the SIM card's data plan. Alternatively, it can connect to an existing Wi-Fi network to enable VoIP calls, making it suitable for NBN-enabled environments or as a failover for cellular calls.

Key functionalities include:

Cellular Calls: Supports 3G/4G networks for standard mobile phone calls. VoLTE (Voice over LTE/4G) is enabled for calls over the data network, provided a compatible SIM card is used.
VoIP Calls: Allows calls over the internet using a SIP account, offering the possibility of a landline number. Up to two SIP accounts can be configured.
Wi-Fi Access Point (Tethering): Creates a Wi-Fi hotspot, enabling other devices to access the internet via the phone's SIM card data. This is particularly useful in areas without NBN or as a portable internet solution.
Wi-Fi Client Mode: Connects to an existing Wi-Fi network to facilitate VoIP calls and firmware upgrades.
SMS Messaging: Capable of sending and receiving SMS messages via the SIM card and compatible network.
Call Management: Features include mute, hold, add call (for conferencing), redial, and speakerphone function.
Call Records & Contacts: Maintains a log of dialed and received calls and stores contacts from both the SIM card and phone memory.
Voice Message: Supports voice mailbox access for SIP accounts.
Emergency Calls: Can make emergency calls (e.g., dial 000) regardless of configuration, provided a mobile network is available.
