VoIP Q&A: Failover Port on Cisco SPA232D ATA

Questions about VoIP devices and services are regularly submitted to VoIPSupply.com through a technical support ticket or via the “Ask The Expert” tab on our product pages.

We respond to these requests directly but more often than not, this Q & A would be helpful for lots of other folks.

Below are your VoIP questions answered – Real questions from real people just like you.

Q: In case that my Internet Provider or SIP provider fail, has the Cisco SPA232D the survival option through it’s FXO port?

Cisco SPA232D Analog Telephone Adapter with Built-In DECT

A: The Cisco SPA232D ATA is an FXS/FXO gateway with DECT so that in addition to using your analog phones and fax machines with VoIP you can, with the addition of an integrated DECT base station, also add up to five Cisco SPA302D handsets to communicate with it.

In regards to your question, the answer is simply “Yes.”

For more detail I will refer to the post of one of our former colleagues who wrote the post, FXS and FXO – You should be in the know:

Some ATA’s also have an FXO port. This connects to the wall jack by the computer to provide failover. In this case, in the event of internet failure, you can still make telephone calls via the POTS line. Also, you can use the FXO port to make free local calls on your POTS line.

FXO ports are most often used on Gateways and PBX’s to support Failover or Fallback as mentioned above.

For more information on all of the FXO control settings, check out the Cisco SPA232D Datasheet.
