REFERENCE ARCHITECTURE
See Mediatrix S7 / S7 LP in the complete voice path.
A product decision is only correct when both sides of the interface, the security boundary and the operating model are considered together.
NO PUBLIC INTERNET REQUIRED
Private LAN / isolated IP network
Local phones, a local IP PBX, Mediatrix gateways and Sentinel can exchange SIP calls entirely inside the organization. The voice path can remain on a private LAN, VLAN, campus network or isolated operational network.
OPTIONAL FOR EXTERNAL SERVICES
SIP carrier, PSTN, Teams or cloud
An external connection is used only when calls must reach public numbers, remote sites or hosted services. If the required call path is entirely local, the system can stay on the private network.
ANALOG / LEGACY EQUIPMENT
Analog phones
Guest rooms, offices or facility phones connect to individual FXS ports.
Facility endpoints
Intercom or emergency devices require endpoint-specific validation.
Long copper loops
S7 LP is selected only where its long-loop characteristics match the field requirement.
FXS / FXO / PRI / BRI
16 / 24 FXS
Mediatrix S7 / S7 LP
High-density FXS migration for 16 or 24 analog endpoints; S7 LP serves validated long-loop needs.

INTERNALLocal IP PBX / call server
Controls extensions and internal routing on the private network. It may remain fully on-premises.
Local calls stay localPhones and the on-site PBX can communicate without a public Internet connection.
OPTIONAL EXTERNAL PATH

READING THE DIAGRAM
What the gateway changes—and what it does not
- Phone or endpoint
- Creates or receives a call. An analog endpoint needs an FXS interface; an IP phone connects directly to the data network.
- Fax or modem
- Sends data as audio. It must be tested through the complete gateway, network and carrier path—not only for dial tone.
- Mediatrix gateway
- Converts analog or digital voice interfaces into SIP/IP while preserving validated legacy equipment.
- Cloud voice platform
- Hosts communications services such as Microsoft Teams Phone or CCaaS outside the customer site.
Conceptual architecture — final topology, capacity and interface configuration require validation.
GATEWAY SELECTION
Match the interface to the field requirement.
Port count alone is not enough. Endpoint behavior, line length, signaling, fax or modem transport, power and carrier acceptance all affect the final choice.
Always validate the exact SKU, interface modules and supported endpoint behavior before ordering or replacing an active line.| Selection factor | 4102 / 4102S | C7 Series | G7 Series | S7 / S7 LP |
|---|---|---|---|---|
| Primary role | Two-port analog adapter | Compact multi-interface gateway | Digital and analog media gateway | High-density FXS gateway |
| Interfaces | 2 FXS | FXS / FXO / BRI by model | PRI / BRI / FXS / FXO by model | 16 or 24 FXS |
| Deployment fit | Small site or single service | Branch and mixed legacy edge | PBX and TDM modernization | Campus and high-density analog |
| Special consideration | Fax / modem validation | Exact model configuration | Trunk and channel design | S7 LP for validated long-loop needs |
FREQUENTLY ASKED
What to know before the next step.
Confirm deployment model, concurrent sessions, registered users, interfaces, codecs, carriers, resilience and operational ownership before choosing the final model or SKU.
Validate the exact hardware or virtual configuration, DGW release, license, power, interface modules, interoperability and support coverage.
Use the linked M5 data sheet for selection and the Media5 documentation portal for configuration, installation and release-specific guidance.
