I am having an issue with getting a busy tone when I answer an incoming call. I can make an outgoing call fine, and it will connect to the user with no issue. However, when I dial in to the phone, it rings fine, but when I answer it gives me a busy signal and then hangs up after a set number of seconds.
Other sip clients, linphone work fine, as well as a separate SIP desk phone. This one phone is having an issue with connecting the incoming call.
Thanks for the help.
