I have just gone onto the NBN and now am trying to get the phone services sorted.
I've bought a SPA232D came with the SPA-302D Handset. I have that working fine calls in and out over VoIP.
I have a couple of DECT phones being Commander and Doro units.
The commander one Registered fine, I was able to get it to bring up a dial tone, I've done something I'm not sure what, now I get an Engaged Tone.
The Intercom works fine between the two.
Any suggestions.
