Hi, I have an annoying problem, because it is not always there. A customer is running 3CX v12.5, use a Call Queue with 10 agents. Yealink T26P v22.214.171.124 Phone call comes in and is picked up. Other phone keeps on ringing, referring to the same call as the one that was just picked-up. When the ringing phone is picked-up, there is no caller (as it has been picked-up already). 3CX log does not show any issue. Do somebody recognize this issue or can point me into the right direction to investigate this? Thank you for your help.
