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.
Legacy phone systems may still work, but they often come with hidden costs, limited scalability, and little support for hybrid work. Aging hardware, ongoing maintenance, and rigid infrastructure can quietly hold businesses back as they grow. Cloud-based VoIP systems remove these constraints by reducing telephony expenses, improving flexibility, and enabling teams to communicate seamlessly from anywhere. For many organizations, modernizing business telephony is no longer optional, it is a practical step toward efficiency and resilience.
A streamlined integration connects the Vodia PBX with the ElevenLabs Voice AI Platform using a lightweight IVR JavaScript script and native SIP REFER for call transfers. Audio and call control are handled entirely through standard SIP signaling, while all conversational logic, prompts, voice selection, and routing rules are configured in the ElevenLabs dashboard. This approach removes the need for webhooks or WebSocket connections and keeps the PBX side intentionally minimal, making the deployment clean and production-ready.
Multi-tenant architecture allows MSPs to manage multiple customers efficiently on a single, secure PBX while maintaining strict tenant isolation. By sharing infrastructure, MSPs can reduce operational costs, apply updates and security patches centrally, scale customers on demand, and onboard faster without increasing complexity. As cloud and SaaS models continue to dominate, a well-designed multi-tenant phone system provides the control, flexibility, and reliability MSPs need to support growth, evolving requirements, and modern communications workloads.
