Our system has been working fine for many months but we've recently realised no calls are getting through (we're a small team with very few incoming calls, hence us not realising!!)
Outgoing and internal calls all seem to work.
At the SIP end, I get the message "call rejected".
Can anyone point me to what might be wrong?
Or how I might go about diagnosing the problem?
Below is the Event Log entry.
