VoLTE Roaming Management

Why VoLTE Roaming Is Critical Now

  • Traditional roaming often falls back to 3G, depriving users of VoLTE’s superior voice quality, speed, and features during roaming 
  • Phasing out legacy networks demands VoLTE readiness; operators can’t reliably shut down 3G until VoLTE roaming is fully deployed 


🔧 Core Capabilities & Offerings

VoLTE Steering & Policy Management

  • Dynamically route roamers based on handset compatibility, quality, and profitability.
  • Tailor policies for users, SIM profiles, and network types—ensure only eligible devices use VoLTE 
  • Improve call completion and user experience with location-aware call correction and shortcode translation 


VoLTE Roaming Testing & QoE Monitoring

  • Launch automated, periodic tests that reflect real roaming scenarios, including VoLTE, RCS, VoWiFi, and SMSoIP 
  • Monitor critical KPIs like registration times, call setup, RTP jitter, packet loss, and POLQA voice quality 


Profitability Analytics & Forecasting

  • Run real-time analytics to assess cost-benefit of VoLTE vs. circuit-switched roaming.
  • Leverage forecasting and budgeting tools for smarter IOT negotiation and wholesale margin optimization 


Legacy Interworking via Smart Mediator & RoamFlow

  • Smart Mediator bridges 2G/3G infrastructure to LTE/VoLTE, facilitating decommissioning of legacy nodes 
  • RoamFlow enables VoLTE for roamers even if home operators lack VoLTE agreements—securing inbound voice revenue
