Secure your SIP trunks, SMPP binds, and signalling links with carrier-grade IKEv2/IPSec tunnels. Encrypt all traffic between your on-premise PBX, SMPP application server, or data center and the MOBITELSMS platform — preventing eavesdropping, call interception, and man-in-the-middle attacks on unencrypted telecom protocols.
The SIP protocol transmits call setup signalling — including caller ID, called number, authentication credentials, and call routing decisions — in cleartext by default. SMPP similarly transmits message content, phone numbers, and authentication credentials without encryption unless TLS is applied at the application layer. On the public internet, unencrypted telecom traffic is exposed to passive interception by ISPs and state actors, active MITM attacks that redirect calls or inject forged messages, credential harvesting from SIP REGISTER and SMPP BIND PDUs, and toll fraud via session hijacking. IPSec tunnels encrypt the entire IP traffic flow at the network layer, protecting all protocols — SIP, SMPP, RTP, SCTP — regardless of whether application-layer TLS is configured.
Unencrypted SIP and SMPP are an unnecessary risk. Our IPSec VPN onboarding takes under 30 minutes — we provide the configuration, you apply it to your router or firewall, and your traffic is encrypted end-to-end.
