Asterisk
Asterisk PBX and media-server engineering for extensions, dialplans, queues, and integrations.
Asterisk remains a workhorse for business telephony and custom voice applications. We configure, harden, and integrate Asterisk for dialplans, queues, IVR, recordings, and API-driven control—whether as a standalone PBX core or as a media component behind a SIP proxy layer.

Depends on the workload. Asterisk is strong for classic PBX and custom dialplan apps; FreeSWITCH often fits media-heavy and multi-tenant designs. We help you choose deliberately.
