Position Overview
We are seeking an experienced Telephony Solutions Engineer to lead client integrations with telephony systems and provide technical solutions across our platform. This is a client-facing role requiring US shift alignment.

Key Responsibilities
  • Own and manage telephony system integrations for all clients.
  • Design and implement cloud telephony solutions.
  • Collaborate directly with clients to understand requirements and deliver solutions.
  • Troubleshoot and optimize VoIP/SIP implementations.
  • Provide technical support and consultation to clients.
  • Work closely with internal teams to ensure seamless integration delivery.
  • Lead the technical setup of SIP trunks with Indian Tier-1 carriers (e.g., Tata Tele Business Services (TTBS) and Jio Business).
  • Carrier & Network Management:
    1. Manage IP-Authentication, Header manipulation, and NAT traversal to ensure calls reach the AI media server.
    2. Line Provisioning: Handle DID (Direct Inward Dialing) allocation and porting of existing numbers from legacy PRI lines to modern SIP infrastructure.
    3. Act as the primary technical point of contact for carrier support teams (Tata/Jio) and cloud providers (Twilio/TCN) to resolve circuit outages or routing failures. [Must have high ownership]
  • AI Integration & Voice Quality:
    1. Configure gateways and Session Border Controllers (SBCs) to route PSTN audio into the AI pipeline (STT/TTS engines).
    2. Set up and debug webhooks (e.g., TwiML or TCN APIs) that tell the AI how to handle "Busy," "No Answer," or "Machine Detected" statuses.
    3. Optimize voice quality using appropriate codecs (G.711, G.729, Opus) to ensure the AI "hears" the customer clearly even on low-bandwidth mobile networks.
  • Advanced Debugging:
    1. Deep dive into SIP, RTP, and RTCP protocols to troubleshoot "One-way audio" or "Dead air" issues.
    2. Implement tools like Wireshark or sngrep to capture SIP traces and analyze call failures. [Must have high ownership]
Required Qualifications
  • 3–5 years in VoIP/Telephony Engineering, specifically with SIP Trunking.
  • Strong expertise in Cloud Telephony platforms.
  • Proficient in VoIP protocols and technologies.

  • Working knowledge of RTPEngine for media handling.
  • Client-facing experience with excellent communication skills.
  • Familiarity with SBCs such as Kamailio, OpenSIPS, or Sonus/Ribbon.
  • Knowledge of protocols like SIP, WebRTC, RTP, and TLS (for secure SIP).
Preferred Skills
  • Knowledge of telecom protocols (SIP/SDP, RTP, SIPS, SRTP).
  • Familiarity with telecom infrastructure and carriers.
  • Problem-solving and analytical thinking.
  • Project management capabilities.
  • Python / Bash skills to extract information from PCAPs.
