CISCO

Cisco analog telephone adapters are listed here. You can pick a 2-port ATA for multiplatform firmware with an extra LAN port, a 2-port analog telephone adapter for MPP and a power adapter for the ATA191 and ATA192.

An ATA lets one analog phone or fax machine join a VoIP service, so small offices keep their handsets when switching to SIP. A spare power adapter also fixes a unit that will not start. Call the KX-TD team at (866) 205-4112 for help.

Before you order

  • Check your firmware. The 2-port ATAs are for multiplatform (MPP) firmware, so confirm your VoIP service supports it.
  • Count your analog devices. Each ATA has 2 ports, so count the phones and fax machines you need to connect.
  • Match the power adapter. The power adapter is for the ATA191 and ATA192.
  • Not sure? Send us your service and we will confirm the ATA.

Cisco ATA buying guide

What an ATA does

An analog telephone adapter lets an analog phone or fax machine connect to a VoIP service. The 2-port units here handle two devices. One version has an extra LAN port. Check that your VoIP provider supports multiplatform firmware.

Fax and power

Fax over VoIP can be tricky, so test it after setup. If your ATA will not start, the problem may be the power adapter. A spare adapter for the ATA191 or ATA192 is listed here. Match the adapter to your model.

Common questions
