I have an IPO 8.018 that we have registered a Aastra 6731i as a SIP extension on the system. We can call from the Aastra to other extensions but when we try to call the Aastra it will go busy as soon as we try to answer. This is my first attempt at SIP phones and I got polycoms connected to it just fine.
I've googled and checked here but the Aastra info seems scarce, any help would be appreciated.
