Soundstation duo - switching between PSTN and SIP.

Hello!

Please tell me.

Soundstation duo is connected via PSTN and SIP at the same time.
By default is SIP mode for out call. How to switch between modes PSTN/SIP if you want to make a call via PSTN and then again via SIP?

Re: Soundstation duo - switching between PSTN and SIP.

Hello @Andrew_2020 ,

 

Welcome to the Poly Community.

The design of the SoundStation Duo is usually to utilize SIP and if the server is down it fails back to PSTN.

 

There is no easy way to my knowledge to toggle between SIP and PSTN but you can navigate the Menu via Menu > 3 for Settings > 2 for Advance > Enter the password > Select 1 for Admin Settings > 1 for Operational mode

 

If this is too many steps have a look at the EFK section:
