DaraVoiceTech

DaraVoiceTech builds Dara, an AI backup receptionist for veterinary practices. Dara picks up calls a busy front desk can't reach, day or night, takes appointment, refill and callback requests, and routes emergencies to the on-call team. It never gives medical advice. It sends medication refills to the veterinarian for review and can connect with DaySmart Vet and Cornerstone. In a 60-day pilot at a San Diego veterinary care coordination center serving 12 clinics, missed calls fell from 673 to 0.

DID & DIALER

DID & DIALER is a comprehensive cloud-based VoIP and telecommunications software platform designed specifically to empower B2B call centers, US freight dispatchers, and offshore teams. By providing premium US Direct Inward Dialing (DID) numbers, our platform combines high-fidelity voice infrastructure with a suite of advanced conversational tools, ensuring seamless global communication. A core strength of DID & DIALER is our commitment to global accessibility and strict telecom compliance. We are fully optimized for offshore operations, explicitly ensuring that all features—including US carrier compliance and messaging regulations—work flawlessly for businesses and BPOs operating in Pakistan. Whether you are managing a high-volume freight dispatch floor in Lahore or operating as an independent dispatcher, DID & DIALER provides the enterprise-grade infrastructure required to connect with US clients without geographic limitations or blocked routes. Key Features Include: * Live Subtitles (The "Accent Eraser"): Our industry-leading, real-time transcription engine instantly converts fast-paced US speech, poor audio connections, and complex regional accents into highly accurate text on the agent's screen. This dramatically reduces miscommunications over freight rates, MC numbers, and pickup addresses, acting as a real-time safety net for offshore dispatchers and boosting overall confidence. * Conversational 10DLC SMS: Move beyond standard voice calls with fully compliant, person-to-person (P2P) SMS messaging. We manage the complex 10DLC (10-Digit Long Code) campaign registration process, allowing your agents to text US truckers and brokers directly from their unified dashboard without the risk of carrier filtering or spam blocks. * Manager & QA Dashboard: Equip floor managers with powerful oversight capabilities. Floor supervisors can monitor live text streams of active calls, utilize automated hold-state billing pauses to prevent cost overruns, and search archived transcripts to streamline Quality Assurance and resolve broker disputes instantly. * Unified Agent Console: A clean, low-latency, and responsive interface that centralizes active call controls, live transcriptions, and conversational SMS text messaging onto a single, distraction-free screen. By merging reliable SIP voice routing with cutting-edge transcription and strictly compliant messaging architecture, DID & DIALER eliminates the traditional friction of offshore communication. We ensure that your Pakistani dispatch agency is equipped with the exact same compliant tools, capabilities, and professional clarity as a native US-based call center.
