Voice Specialist
vonage · Bengaluru, Karnataka · Posted 2 days ago
Be the subject matter expert for voice routing quality across Vonage's global carrier network, including leading the migration of voice services from IBM Data Centres to AWS.
Why this role matters:
Voice traffic is one of the most technically demanding areas of the Vonage network — combining SIP protocol complexity, real-time quality measurement, and multi-region carrier relationships. As a Voice Specialist, you will be the subject matter expert for voice routing quality and configuration, working alongside the broader Technical Routing & Quality team to ensure Vonage voice services meet the highest standards of reliability and performance.
Your key responsibilities:
- Own the configuration, testing, and ongoing optimization of voice routing across global supplier connections on both API and Applications (RVE/GCS) platforms
- Monitor voice quality metrics — ASR, NER, MOS, and PDD — and drive proactive and reactive improvements
- Investigate and resolve voice carrier degradations, routing anomalies, and SIP-level issues
- Onboard new voice carriers and validate SIP connectivity, including peering agreements and codec/dial plan configuration
- Manage voice routing for North American peering traffic and coordinate with the Apps side where platforms overlap
- Support the migration of voice services from IBM Data Centres to AWS
- Contribute to the development of automated alerting and incident resolution tooling for voice
- Act as voice routing SME for cross-functional teams including Product, Engineering, and Carrier Partnerships
- Provide input on Network API and RCS voice routing requirements as new services come to market
- Overall Experience 5 years to 8 years.
- Strong hands-on experience with SIP protocol, voice routing platforms, and carrier interconnect
- Proficiency in interpreting voice quality KPIs (ASR, NER, MOS, PDD) and translating them into routing actions
- Experience with a VoIP or cloud voice platform ( e.g. Vonage RVE/GCS, FreeSWITCH , Kamailio , or equivalent)
- Ability to diagnose complex SIP-layer issues, including codec negotiation, registration failures, and call setup errors
- Strong collaboration skills — able to work effectively with carrier partners, product managers, and engineering teams
- Comfortable in an operational environment with on-call responsibilities
