VVX 400 PSTN how to?


This forum seems mostly about the Soundstation but I want to set up a PSTN line on a VVX 400 somehow.


Does anyone know what equipment I need to be able to do this? Is it even possible?


Thank you

Hello Samuurai,

welcome to the Polycom Community.

The VVX is a VoIP phone so you need a service that translates VoIP to PSTN.


You can get cards that work with Asterisk as an example that can terminate a analog line.


Polycom does not manufacture any equipment like this so please check somewhere else.

After lots of reading I found out I need an FXO Gateway. I'm going to try the Grandstream HandyTone 503 as I only have one line.
