Approved mobile-number access
Route defined inbound cellular calls into the PBX or SIP platform.
Connect cellular voice to your contact center.
Bring approved cellular voice traffic into the contact-center environment so inbound, outbound, regional or backup calling can follow defined routing, agent and recording policies.
The cellular voice requirement
Control the cellular path into your voice platform.
A contact center may need approved mobile-network voice channels for a defined inbound, outbound, regional or backup requirement.
The design must align channel capacity, call routing, SIP interworking, mobile coverage and operator policy without relying on grey-market traffic practices or guaranteed connection outcomes.
Approved cellular calling path
Present a permitted mobile-network route for selected outbound traffic.
Location-specific mobile service
Use local operator access where the service and regulatory design allow it.
Alternate external voice path
Assess cellular channels as a backup route for specified calls.
Cellular voice boundary
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.

Selected endpoint and workflow layer
Validate the 32-channel requirement
Confirm traffic, frequency bands and operator requirements before selecting the SWG-4032 variant.
Keep product responsibilities explicit
The OpenVox gateway supplies the cellular-to-SIP boundary, not the contact-center application.
Test routes and agent outcomes
Confirm inbound, outbound, caller identity and failure behavior with the selected platform.
Use SWG-4032 for cellular access, not contact-center logic.
SWG-4032 supplies the 32-channel GSM, WCDMA or LTE voice-to-SIP 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 benefit, policy avoidance, guaranteed answer rate or contact-center application feature is claimed.
Cellular voice access
SWG-4032G, SWG-4032W and SWG-4032L provide documented GSM, WCDMA and LTE voice roles.
