AT&T IP Flexible Reach is a SIP trunking service that provides integrated access for both IP and TDM PBX environments. It consolidates voice and data services, simplifying operations and potentially reducing costs. When paired with the Vodia IOP PBX, this integration allows seamless management of SIP trunks, including features like fax over email or connecting traditional fax devices with an FXS adapter. To configure, you’ll need the IP Flex service with "SIP handoff" for direct SIP call routing. With Vodia's SIP trunk template, setting up AT&T Flexible Reach is streamlined, matching DID numbers to extensions or hunt groups by default, making it ideal for businesses seeking reliability and ease of use.
AT&T IP Flexible Reach is a Session Initiation Protocol (SIP) trunking service that delivers integrated access for IP PBX, TDM PBX or Key System environments. It provides potential total cost benefits through the consolidation of voice and data – one provider, single transport and management options.
You can easily configure these services with the Vodia IOP PBX server and provide dial tone to all your SIP desktop phones. You can connect fax using an FXS SIP device, or let the Vodia IOP PBX deliver the fax straight to your customer via email.
When ordering the SIP service, it's important you get the IP Flex service with “SIP handoff” - this means inbound and outbound phone calls will be delivered directly via SIP and not over analog lines or PRI.
Flexible Reach SIP Trunk is now part of the Vodia SIP Trunk template. Once you have configured AT&T, log in to your Vodia IOP device, navigate to your domain and scroll down to Trunks. Click create and select AT&T.

By default, Vodia will send any incoming call to the DID number programmed to its respective extension, hunt group, ring group or IVR account (e.g., Auto-Attendant) and distribute that inbound call to a specific account when the caller presses a digit to make a choice. The Vodia AT&T template does a good job of matching the correct DID number by default, which makes it a great option for integrators looking for an easy, reliable solution.
Join Vodia Networks on April 8 for a live, in-depth webinar on how real-time media streaming is powering the future of voice communication. Discover how Vodia PBX version 69.5.6 enables seamless AI integration, live call transcription using the Whisper API, and secure voice data handling. Hosted by Sales Engineer Eric Altman and VoIP Engineer Hamlet Collado, this session will walk you through real-world use cases, including OpenAI and Google Speech-to-Text integrations, MS Teams support, and new security features. You’ll also get a first look at Vodia’s AI roadmap and have the opportunity to ask your questions during a live Q&A.
Whisper, OpenAI’s Automatic Speech Recognition system, delivers multilingual, noise-tolerant, and technical-language-ready transcription through a streamlined encoder-decoder architecture. With Vodia PBX’s integration, organizations can choose between using OpenAI’s service or hosting Whisper AI locally for complete data sovereignty and control. This on-premise option ensures that sensitive call data stays within your infrastructure while still benefiting from powerful transcription capabilities. To explore deployment options, see our Whisper AI on-premise setup documentation, review a self-hosted integration example, or follow our cloud-based call transcription guide.
Vodia Sales Engineer Eric Altman attended Enterprise Connect 2025 on March 18 and 19, where he connected with partners and gained insight into the future of enterprise communications. AI was the clear focus of the event, with discussions centered on agentic systems, chatbots, and generative technologies. “It was certainly the main element in the atmosphere,” Eric noted. He also shared his excitement about Vodia PBX version 69.5.6, which includes real-time AI integration with OpenAI and call transcription using the Whisper API. The event confirmed that AI is rapidly becoming a core component of modern communication platforms—and Vodia is well-positioned to lead the way.
