We can only locate one basic model, the Planet VIP-156PE from:
However, it is intended for use with Planet’s own PBX which uses * (asterisk) as a kind of initiate character which, of course, isn’t very practical with Asterisk as the PBX …
Also, 3Com has a more sophisticated model but it seems to work only with a 3Com PBX.
So where to look? Any suggestions, please?
