Three extensions? So is that like one 57CT base stations and two remotes? I thought you said there was only one.
In any case, i dont think the 57CT supports a separate account just for the cordless portion, but Ive ordered one in to figure it out. Ill need it eventually anyways.
use the subaccount for each DID and just use the Aastra's intercom function to accomplish your extension calling. Also, forget about the main account and just use subs.
Boarding a plane now, so responses will be delayed.
