I am having an issue with one of my customer sites where on the Yealink T38G phones whenever they miss a call (intercom or external) there are two entries for each call. All the miss calls have a red x in front of them and if you tried to return the call you are given a Forbidden error message and the call don’t go through. Any ideas on what may be causing this and what I can do to fix? The phones are running firmware version 38.70.0.125 or 38.70.0.115. Thanks
