OpenSIPS#

OpenSIPS is an open-source SIP signaling server for routing calls and messages between SIP devices, PBX systems, and service providers. Use OpenSIPS 4.0 with DIDWW to route voice calls over SIP trunks and to send and receive SMS over SMPP.

  • Route incoming calls from DIDWW numbers to a user agent behind OpenSIPS.

  • Place outbound calls through DIDWW Outbound Trunks with SIP digest authentication.

  • Use Static Endpoint or Dynamic Registration inbound trunks.

  • Send SMS from a user agent through a DIDWW SMPP ESME trunk.

  • Deliver inbound SMS and delivery receipts to the user agent as SIP MESSAGE requests.

  • Optionally encrypt the SMPP connection with TLS.
