Download the current Audiotrix C2 and C4/C8 product brochures from M5 Technologies. PDFs are in English. Confirm the exact model and configuration before ordering.
Validate the complete fax call path.
A listed T.38 feature does not establish compatibility with every fax machine, carrier or firmware version. Before choosing one ATA for both voice and fax customers, test your actual service.
Identify the build
Record the exact ATA model, hardware revision, firmware, carrier and sending/receiving fax models.
Exercise real calls
Include both directions, short and long documents, ECM on/off where applicable, T.38 negotiation and the intended G.711 fallback.
Document a failure
Provide reproducible steps, timestamps, expected and observed results. Arrange secure transfer of sanitized SIP/media traces with support.
Firmware and support questions
Does Audiotrix use the same firmware as Mediatrix or an OEM router?
Do not infer a device’s SIP stack or media implementation from its enclosure or from another product using M5T software. Ask M5 to confirm the software and maintenance scope for the exact Audiotrix revision you are evaluating.
Can a reported T.38 issue be fixed?
A fix or delivery date can only be confirmed after technical review of the exact build and a reproducible test. Request a written assessment of support ownership and the proposed next step before committing to a rollout.
Can I use a DGW fax guide to configure an Audiotrix?
Use documentation explicitly applicable to your model and firmware. The DGW fax guide in the resource directory is for the DGW platforms it documents; it is not an Audiotrix configuration guide.
Discuss an Audiotrix deployment
Tell us which model, firmware and call behavior you need to evaluate.

Teams Direct Routing: verify the listed configuration
Microsoft lists the Mediatrix Sentinel Series for Teams Direct Routing with specified DGW firmware. Confirm the supported firmware and deployment configuration for your project.
Certification is tied to the SBC and software listed by Microsoft. It does not independently certify Audiotrix ATAs or the complete emergency calling service. Use the current Microsoft list and a release-specific M5 deployment guide when planning an evaluation.
