Access to approved mobile numbers
Route defined inbound cellular calls to the PBX or SIP platform.
Connect cellular voice to your contact center.
Integrate approved cellular voice traffic into the contact center environment so that inbound, outbound, regional, or backup calls can follow defined routing, agent, and recording policies.
Cellular voice requirements
Control the cellular path to your voice platform.
A contact center may require approved mobile network voice channels for a defined inbound, outbound, regional, or backup calling need.
The design must align channel capacity, call routing, SIP interoperability, mobile coverage, and carrier policy without relying on gray-market traffic practices or guaranteed connection outcomes.
Approved cellular calling path
Present an authorized mobile network route for selected outbound traffic.
Location-specific mobile service
Use local carrier access where service and regulatory design allow.
Alternative external voice path
Evaluate cellular channels as a backup route for specified calls.
Keep mobile access, gateway, and contact center roles distinct
SWG-4032 converts up to 32 approved cellular voice channels to SIP, while the selected PBX or contact center platform remains responsible for queues, agents, and policy.
Use SWG-4032 for cellular access, not contact center logic.
SWG-4032 provides the GSM, WCDMA, or LTE to SIP voice path; the selected PBX and contact center software remain responsible for queues, agents, skills, recording, and monitoring.
Define the gateway role and its limits.
No caller ID manipulation, SIM rotation advantage, policy evasion, guaranteed answer rate, or contact center application function is claimed.
Cellular voice access
SWG-4032G, SWG-4032W, and SWG-4032L provide the documented GSM, WCDMA, and LTE voice roles.
PBX interoperability path
The gateway presents cellular voice to the selected SIP or IP-PBX environment.
Defined trunk role
Cellular channels can be designed as primary or backup trunks for approved traffic.
Capacity and policy validation
Channels, coverage, carrier conditions, routing, and failure behavior are confirmed before deployment.
Build a governed cellular-to-SIP plan.
Share traffic direction, concurrent calls, mobile operators, regions, PBX platform, routing, and backup requirements. OpenVox can help define gateway capacity and validation.
