Telefónica incorporates AI for businesses voice communications vs. 3GPP/ITU specifications
Executive Summary:
Telefónica España made an announcement this week which indicates that Voice could be an important AI monetization opportunity for telcos. The Spain based telecom group is positioning its business voice portfolio around a key differentiator: the ability to embed AI-enabled capabilities directly into conventional fixed and mobile telephony, without requiring enterprises to migrate users or workflows to a separate communications platform. It is incorporating generative AI features into its network for things like call transcription and summarization, which it says is will transform “every voice conversation into usable, structured and actionable information,” as week as virtual assistants on fixed-line and mobile.
Targeted at large enterprises, public-sector organizations, and mid-sized businesses, the enhanced portfolio is intended to shorten call-response times, increase the proportion of calls handled, and convert voice interactions into structured, actionable business information. Telefónica reports that the AI-enabled tools can reduce time spent managing calls by an average of 60%, enabling organizations to handle a higher volume of customer interactions.
Telefónica has integrated artificial intelligence across its business voice offerings—from basic mobile services to advanced PBX and cloud-based telephony platforms—as part of its evolution toward intelligent voice communications. The proposal incorporates generative-AI functions within the Telefónica network, including call transcription, automated summarization, and virtual-agent capabilities. These functions are designed to preserve information that might otherwise remain unstructured within voice conversations, while helping organizations reduce missed opportunities and improve operational responsiveness.
Javier Pascual, Director of Product, Pre-sales and Provisioning at Telefónica Spain, said:
“We are the only operator that offers intelligent transcription and summarization of calls over fixed and mobile voice, making us the best way for companies to access digital technologies. This pioneering solution, which integrates generative AI into standard telephony, allows our clients to summarize and transcribe calls, as well as integrate 100% of virtual agents using natural language, thus improving productivity and agility.”
Cross-Portfolio Intelligent Voice:
Telefónica’s approach spans enterprise, public-administration, corporate-mobile, and mid-market customer segments. It applies to traditional and cloud-based voice solutions, including:
-
Centrex IP, Telefónica’s converged fixed-mobile business voice platform.
-
Centrex 365, a Microsoft-based cloud voice offering integrated with collaboration tools.
-
Enterprise mobile voice services.
A core capability is AI-based transcription and summarization of calls. By transforming voice conversations into searchable and structured records, the feature can support knowledge capture, customer-service follow-up, compliance-related documentation, and analytics workflows.
The company is also introducing Centrex AI, a virtual-agent capability based on advanced language models. Centrex AI is designed to support next-generation generative-AI interactions across channels beyond voice and to integrate with customer business applications. The virtual agents are intended to interpret natural-language requests in context, automate repetitive interactions, and provide faster, more consistent responses.
Telefónica states that the platform supports more than 100 languages and can operate continuously, enabling 24/7 multilingual customer engagement.
Operational and Vertical Use Cases:
Telefónica reports that the AI-enabled capabilities can improve agent efficiency by as much as 60% by reducing time devoted to repetitive tasks. The company also cites potential increases of more than 10% in the number of interactions managed, reflecting improved call-handling capacity.
Initial use cases focus on healthcare, public administration, retail, and industrial enterprises:
-
In healthcare, a WhatsApp-based AI agent can schedule appointments, provide immediate confirmations, and support multilingual exchanges.
-
For municipal governments, voice agents can address common citizen queries in multiple languages and route calls to the appropriate department.
-
For automotive dealerships, virtual agents can help manage service appointments and customer inquiries related to vehicle sales.
By integrating generative AI functions into the existing voice network and service portfolio, Telefónica is seeking to extend intelligent automation to established telephony environments rather than treating AI communications as a standalone application layer.

Editorial Analysis:
Telefónica’s offer as an operator-integrated, proprietary AI overlay on existing fixed/mobile and cloud voice services, rather than as a service defined by 3GPP or ITU. The business voice offering builds on standardized fixed/mobile voice and cloud-telephony foundations, while its generative-AI functions—call transcription, summarization, and virtual-agent integration—appear to be operator- and vendor-implemented capabilities. Current 3GPP work provides enabling mechanisms for AI/ML in 5G systems, whereas ITU-R’s AI-related IMT work addresses radio-network evolution rather than AI-enhanced enterprise telephony.3GPP.
Relevant 3GPP specifications:
3GPP’s AI/ML work is primarily focused on network and RAN optimization, AI/ML model transfer and lifecycle management, data collection, and interoperability. Notably, 3GPP has stated that it does not plan to standardize the AI/ML models themselves; it instead standardizes the supporting mechanisms and controls.3gpp
ITU-R versus ITU-T:
ITU-R: There are no ITU-R Recommendations specifically governing AI-based telephony, generative-AI call summarization, or virtual agents. This is consistent with ITU-R’s mission: spectrum, radio propagation, and IMT radio-interface frameworks. Its IMT-2030/6G work includes integrated AI and communication as a broad capability area, but that concerns wireless-system capabilities such as distributed training and inference—not enterprise voice-service features.
ITU-T: This is the more relevant ITU sector for AI telephony and conversational AI, although its work is still largely horizontal rather than specific to IMS/PSTN calling:
-
ITU-T F.748.46 (2025) specifies requirements and evaluation methods for AI agents based on large-scale pre-trained models. Its scope includes recognition, comprehension, dialogue, generation, and reasoning—capabilities directly relevant to virtual voice agents.
-
ITU-T E.AIQ, Framework for quality evaluation of conversational AI systems, is under study in Study Group 12. It proposes KPIs and an “AI Quotient” approach for assessing AI systems in relation to QoS and QoE.itu
-
ITU-T Y.3178 defines a functional framework for AI-based network-service provisioning in future networks.itu
-
ITU-T Y.3661 (2025) specifies an architecture and mechanisms for customer-oriented intelligent network operation, including AI-supported recognition of user intent; this is adjacent to, but not a telephony-service specification

From Sebastian Barros:
Telefónica says the proposition can work across conventional telephony rather than requiring every employee or customer to move into a new collaboration application. That last detail is the one that makes the whole difference for Telcos.
Transcription is not new, Summaries are not new, and AI agents are definitely not new. But putting intelligence around the ordinary telephone call, however, starts to change the economics and strategic position of voice.
Everyone knows how to use a phone! Well, at least 6 billion humans
For most of the last twenty years, intelligence and “coolness” moved away from telecom operators. WhatsApp took messaging; then Microsoft built Teams into the operating system of corporate communications, or Zoom captured meetings. Twilio turned communications into software APIs. Even Salesforce accumulated the customer context surrounding the conversation. Furthermore, players like Apple and Google took greater control of what happens on the handset.
The Telco remained essential, but increasingly invisible. It provided connectivity, numbering, termination, identity, and billing while somebody else built the valuable software layer on top. Enterprise voice became a particularly painful example. Operators owned the phone number and the network, but much of the innovation and margin migrated into UCaaS, contact center software, and cloud platforms.
Telco Smart Voice gives the industry a chance to attack that problem differently. Telefónica does not need to build a better Teams or to convince millions of people to download another communication application. Its potential advantage comes from making the existing telephone service more intelligent. If an employee can make a normal mobile call from a corporate Movistar SIM and have that conversation securely transcribed, summarised, classified, and connected to a CRM workflow, the intelligence follows the communication rather than the application. That sounds like a subtle distinction; however, commercially, it is enormous.
Consider a small plumbing company with eight employees. Today, somebody has to answer the phone, understand the problem, obtain the address, decide whether the job is urgent, check availability, and enter everything into a scheduling system. Many calls arrive while everyone is working. Some go unanswered, and surely some potential customers disappear. Smart Voice could allow the existing business number to become the front door to an automated workflow. The conversation can be understood, the problem classified, an appointment proposed, and the information entered into the operating system. The plumber does not need a contact center transformation program or to install a new app; The business simply has a smarter telephone number…
