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.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

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.
