SWG-M20X

OpenVox SWG-M20X wireless gateway

Bridge GSM, WCDMA, LTE, 4S SIM-capacity, and eSIM mobile access into SIP and IAX2 voice platforms with compact, rack-oriented, and high-channel SWG gateway options.

Bring cellular voice and messaging into the IP voice platform.

OpenVox SWG gateways bridge mobile networks into SIP and IAX2 systems for sites that need cellular voice trunks, SMS/USSD workflows, or eSIM-based mobile access.

  • Route GSM, WCDMA, LTE, or eSIM mobile channels into SIP and IAX2 platforms.
  • Use SMS, USSD, PIN, call-limit, and SMS-limit controls for SIM-based operations.
  • Manage distributed deployments through Web GUI, SSH, logs, capture tools, and OpenVox cloud management.

SWG capabilities for cellular voice access.

Use the same gateway operating model across wireless access projects while choosing the SWG hardware that matches channel count and SIM strategy.

2-32mobile channels

Cellular access into SIP

Bridge GSM, WCDMA, LTE, or eSIM mobile voice channels into SIP and IAX2 voice platforms.

  • Use mobile channels as voice trunks for IPPBX, SIP server, or softswitch environments.

Wireless gateway capabilities for voice and messaging rollout.

Plan the mobile side, IP voice side, messaging workflows, and operations controls together before rollout.

Mobile access planning

  • Choose 2/4, 8, 16, 32, 4S SIM-capacity, or eSIM channel options by site requirement.
  • Use GSM, WCDMA, LTE, or eSIM family options where the local mobile network and project policy require them.
  • Match standard SIM, high SIM-capacity 4S, or eSIM provisioning to the operating model.

SIP and routing integration

  • Connect cellular voice channels to SIP or IAX2 voice platforms.
  • Use trunk registration, trunk grouping, and routing rules to control mobile-to-IP traffic.
  • Apply DTMF, codec, and number-handling settings to align with the upstream voice platform.

Messaging and operations

  • Use SMS send, receive, group send, forwarding, SMS to email, quick reply, and SMS remote control workflows.
  • Use USSD and PIN identification functions where SIM operation requires them.
  • Operate distributed deployments through Web GUI, SSH, logs, packet capture, and OpenVox cloud management.
