Key Challenges
End-to-End Voice Encryption
Unencrypted SIP calls over standard internet infrastructure are vulnerable to interception. Defence networks require SRTP + TLS signalling encryption as a baseline, with options for ZRTP for peer-to-peer media encryption.
Ruggedized Hardware for Harsh Environments
Forward operating locations, border outposts, and outdoor installations require hardware rated for extreme temperatures, dust ingress (IP67), and vibration — standard commercial equipment fails rapidly in these conditions.
GeM Procurement Compliance
All technology procurement for central government and defence must be routed through GeM portal. Vendors must maintain up-to-date OEM authorisations, BIS certifications, and MSQ (Make in India) compliance documentation.
Air-Gapped Network Architecture
Sensitive command-and-control networks must operate in complete isolation from public internet infrastructure, requiring specialised private SIP trunking and on-premises call routing with no cloud dependencies.
