Bug with Sangoma S400 phones

We purchased several Sangoma S400 phones and found that:

• Agent "A" is logged into a Queue 3600
• Agent "B" is logged into a Queue 3600
• Agent "A" calls Agent "B" via internal dial
• While Agent "A" & "B" are talking Agent "A" activates the "Pause" status by pressing 46<Agent "A" extension>
• The result is Agent "B" goes into the status of "pause" when it should be Agent "A"
