I currently have a HDX8000 and C12 Soundstructure. I have been using a ISDN port for teleconferencing via the HDX8000 system. The ISDN will no longer be available hense I want to introduce a Tel1 card to the Soundstructure unit. Will the HDX8000 and Tel 1integrate and can I do VC or teleconference calls.
From looking at the data sheet: http://www.polycom.com/content/dam/polycom/common/documents/data-sheets/soundstructure-telco-ds-enus... , it looks like the TEL1 card needs PSTN connections. I believe you'd need ISDN connections for video. Looks like the C12 provides an audio solution only.
You might be able to use the phone port on the HDX and connect using audio via the C12 to a conference from the HDX.
