Choosing an ideal gateway can be a daunting task, especially when there are many similar solutions on the market. In this article, we’ll compare two popular VoIP gateways from Patton: SN4170 and SN5570 Gateways and help you pick the right gateway that works for you!

The SN4170 PRI Gateway Series

Ideal Users: Small to mid-sized organizations and service providers/ integrators

  • Small-to-medium-sized enterprises looking for effective ways to bridge PBX systems on multiple sites or connect them to a public Internet telephony service.
  • Service providers and network integrators looking for a gateway that matches up to ISDN standards in terms of features and quality.

What’s the difference between the SN4170 and the SN4171 VoIP gateways?

The SN4170 and the SN4171 provide similar features, however, the SN4171 offers an increased memory for users who have higher demands. If you are currently using the SN4170 and would like to have extra memory, you can easily upgrade to the SN4171.

  • Service providers and network integrators looking for a VoIP gateway that matches up to ISDN standards and solves SIP to SIP interoperability issues.
