Model comparison
Every S7 model, compared clearly.
Start with the number of analog endpoints, then choose standard or LP line characteristics. The full order code is finalized after the remaining configuration options are confirmed.
| Model | FXS ports | Maximum FXS cable | Secondary over-voltage protection | Best starting point |
|---|---|---|---|---|
| Mediatrix S716 | 16 | 450 m | No | Standard indoor wiring, up to 16 analog endpoints |
| Mediatrix S724 | 24 | 450 m | No | Standard indoor wiring, 17–24 analog endpoints |
| Mediatrix S716 LP | 16 | 2 km | Integrated secondary protection | Longer loops or demanding wiring, up to 16 endpoints |
| Mediatrix S724 LP | 24 | 2 km | Integrated secondary protection | Longer loops or demanding wiring, 17–24 endpoints |
Installation note: standard S7 units must not be connected to external lines. LP secondary protection does not replace the primary protection required for external lines. Installation must follow the applicable hardware and electrical-safety guidance.

02
Cloud telephony
Provide SIP termination for hosted voice, Unified Communications and IP-Centrex services.
03
Legacy PBX integration
Connect existing analog extensions and PBX environments to modern SIP infrastructure.
04
Branch survivability
Support local continuity for IP phones when a branch loses its WAN connection.
05
Hospitality and healthcare
Preserve room phones, fax machines and other analog endpoints during migration.
06

Frequently asked questions
Answers before you specify the gateway.
Which models are in the Mediatrix S7 family?
The four commercial models are S716, S724, S716 LP and S724 LP. S716 models provide 16 FXS ports; S724 models provide 24 FXS ports.
What is the difference between S7 and S7 LP?
Standard S7 models support FXS cable runs up to 450 m. S7 LP models support runs up to 2 km and add integrated secondary over-voltage protection for more demanding wiring conditions.
Does S7 LP secondary protection replace primary protection?
No. Primary protection is still required when an LP unit is connected to external lines. Standard S7 units do not provide the LP model’s integrated secondary protection and must not be connected to external lines.
Can S7 gateways carry fax and modem traffic?
Yes. The series supports real-time T.38 fax and clear-channel G.711 fax and modem pass-through.
Why does the complete order SKU have more than the model name?
The complete 24-character order SKU identifies the unit configuration and packaging. It can vary with the regional power cord, software profile, support or license options, FXS or FXS-LP cards, bypass option and DSP configuration.
