Hello GrisCorp,
welcome back to the Polycom Community.
The HDX Admin Guide shows:
- Connecting to an Analog Phone Line
You can connect an analog phone line to a Polycom HDX 9000 series, Polycom HDX 8000 series, Polycom HDX 4000, or Polycom HDX 4000 HD system to make regular telephone calls with the system or to add audio-only participants to video calls. The first analog phone or Voice Over ISDN connection does not count toward the number of sites in a call. Additional analog phone or Voice Over ISDN connections, as well as all H.323 audio-only and SIP audio-only connections, do count toward the number of sites in a call.
The HDX 7000 does not have a POTS connectivity to my knowledge.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
