FreJun vs Tata Teleservices: What Our Data Shows
Based on FreJun’s 2025 analysis of 300+ client accounts migrating from legacy SIP providers, sales teams using FreJun’s AI call center software reported a 38% reduction in post-call admin time and a 22% increase in daily outbound call volume within the first 30 days.

For teams evaluating cloud-based telephone systems with CRM integrations, this data point matters: the time saved on admin directly translates to more selling time per rep.
According to the International Telecommunication Union (ITU), VoIP adoption among businesses in Asia-Pacific grew by 18% year-over-year between 2022 and 2024, driven by the shift to hybrid work and the need for scalable, software-defined communication infrastructure. This trend makes choosing the right ai call center software platform — one that integrates with existing CRM and workflow tools — a strategic priority for revenue teams in 2025.

Frequently Asked Questions About Tata Teleservices SIP Trunk Alternatives
1. What Is SIP Trunking And How Does It Work?
SIP Trunking connects a business PBX (Private Branch Exchange) to the public telephone network over the internet using SIP (Session Initiation Protocol). It replaces physical phone lines with a virtual connection, enabling scalable VoIP calling. Businesses pay only for the channels they use, making it significantly more cost-effective than traditional ISDN or PSTN lines for teams with variable call volumes.
2. Why Should Businesses Consider Switching From Tata SIP Trunk?
Businesses switch from Tata SIP Trunk primarily for better CRM integration, AI-powered call insights, and faster onboarding. Tata Tele Cloud Telephony handles basic voice connectivity well, but lacks native integrations with tools like HubSpot, Salesforce, or Zoho. Alternatives like FreJun auto-log every call to CRM, generate AI summaries, and deploy in under 5 minutes — advantages that directly impact sales team productivity.
3. How Does a Cloud Telephony Solution Compare to Traditional SIP Trunk Services?
Cloud telephony solutions offer greater flexibility, faster onboarding, advanced analytics, and seamless CRM integrations compared to traditional SIP trunk services. While SIP trunks handle basic voice connectivity reliably, cloud-based systems are better suited for modern, agile teams needing scalable and data-driven communication tools. Cloud platforms also eliminate hardware dependencies and support remote teams without VPN or on-premise infrastructure requirements.
4. Which Alternative Offers The Best Support For Remote Teams?
FreJun is the strongest choice for remote and hybrid teams. Its browser-based calling requires no hardware, the Chrome extension enables click-to-call from any webpage, and the mobile app keeps agents connected from anywhere. All calls log automatically to CRM regardless of where the agent is working. Vonage is also a solid option for teams needing global number coverage across multiple countries.
5. What Are The Key Benefits Of Using Cloud SIP Services?
Cloud SIP services provide easy setup, automatic call routing, real-time analytics, and native integration with tools like HubSpot and Zoho. Unlike legacy SIP trunks, cloud platforms scale instantly — adding or removing users takes minutes, not days. AI-powered features like call transcription, sentiment analysis, and automated summaries give managers visibility into team performance without manual review of every recording.
6. How Fast Can I Migrate From Tata SIP Trunk To Another Provider?
Migration timelines vary by provider and infrastructure complexity. FreJun deploys in under 5 minutes with no hardware required — users sign up, connect their CRM, and start calling immediately. Larger enterprise platforms like Genesys or Avaya may require 1 to 4 weeks for full deployment depending on custom routing configurations and legacy system integrations. Number porting typically adds 3 to 7 business days regardless of provider.
7. Are SIP Trunks Secure For Business Communication?
Yes, modern SIP trunk providers use TLS (Transport Layer Security) and SRTP (Secure Real-time Transport Protocol) to encrypt voice data in transit. FreJun applies encryption, authentication, and firewall protection across all calls. Businesses should verify that any provider they evaluate supports TLS/SRTP by default, not just as an add-on, and complies with regional data privacy regulations such as GDPR or India’s DPDP Act.
8. Does Tata Tele Cloud Telephony Support CRM Integration?
Tata Tele Cloud Telephony offers limited CRM integration compared to cloud-native alternatives. Native connectors for platforms like HubSpot, Salesforce, Zoho, or Pipedrive are not built into the core product. Alternatives like FreJun provide out-of-the-box integrations with 10+ CRM and ATS platforms, with automatic call logging and data sync that eliminates manual entry entirely — a key advantage for sales and recruitment teams.
9. What Is the Difference Between SIP and VoIP?
VoIP (Voice over Internet Protocol) is the broader technology that enables voice calls over the internet. SIP (Session Initiation Protocol) is the specific signaling protocol that manages how VoIP calls are initiated, maintained, and terminated. Think of VoIP as the category and SIP as one of the standards within it. Most modern business phone systems use SIP as their underlying protocol for call setup and routing.
10. Which Provider Is Best for India-Based SMBs?
Knowlarity and Exotel are the strongest options for India-based SMBs. Knowlarity starts at Rs. 1,999 per month with cloud IVR, virtual numbers, and CRM integration suited to small teams. Exotel offers unlimited concurrent calls and a plug-and-play setup ideal for businesses scaling call volume quickly. FreJun is the better choice when CRM integration, AI call insights, and international calling are priorities alongside India-based operations.
