How to Integrate 3CX with Analog Phones and PSTN

3CX is a popular software PBX with many rich and useful unified communications capabilities. It does NOT however natively support analog phones or PSTN connectivity. So how can you keep your organization connected to the PSTN—whether for fallback/survivability or breakout phone service?

And how can you integrate your legacy telephone handsets with 3CX?

SmartNode to the rescue!

For your analog phones, you need a SmartNode ATA (or FXS VoIP Gateway) that provides FXS ports for connecting the legacy phones to the IP network while converting the analog voice to a SIP media stream, i.e. VoIP.

For PSTN access, you need a VoIP gateway that provides T1/E1/PRI ports to integrate the 3CX phone system with a PSTN network access link (WAN connection).
