Messaging and Telephony Skills

In Legacy systems, Messaging and Telephony primarily involved SMS, MMS, WAP and Circuit switched call management. With the advent of IP based networks, the landscape of this technology vertical has drastically changed. While SMS is still a large revenue churner for many operators, IP based Messaging (such as WhatsApp, Facebook Messenger, Hangouts etc.) and Telephony (Skype, Hangouts, Vonage, and others) have disrupted the communication space completely.

HSC works with leading OEMs and ISVs around the world helping them develop modern messaging and telephony clients, servers and end to end network solutions. Key focus areas for HSC in this space are:

  • SIP/WebRTC convergent mobile client (both Web based and Native) and Interworking Gateway Function development
  • VoLTE and IMS client development
  • Core Network Server development - HSS/HLR, CSCFs, SBC
  • IP based Push to Talk network  solution development (PTT clients, PTT dispatchers, Multicast Gateways)
  • Fixed mobile convergence solution development: Embedded software that can seamlessly switch to/from WiFi/Circuit switched calling and IMS/VCC compliant call continuity server development
  • Extending functionality of traditional SMS gateways - REST API development, web embeddable controls
