Key Technologies : IMS, 3GPP, SIP, IMPS, VoIP, Audio/Video, Windows Mobile, STUN, NAT Traversal.

Abstract: HSC developed an instant messaging and VoIP client for an ISV for Windows Mobile. The client architecture was built in a way that new supplementary services could easily be added without disrupting the core engine. This client was deployed in IMS/3GPP networks successfully. In addition to this, HSC also implemented an integrated STUN client, fully compliant to IETF specifications to aid in NAT traversal.

Customer Benefits:

  • Abstracted engine code - it became very simple for the customer to introduce new features for different verticals in the future
  • Reduced Time to market and increased reliability.
