Unattended answer DR5 8x16

[Rhansul]

Hope I can explain this right.
Every once in awhile when I arive at my business in the AM one of the stations is off hook with the COs attention getting busy signals blarring from the speaker phone. Same Ext. every time. Thought it might be night service kicking in but I believe I have tis disabled.
Any thoughts.
Thanks in advance

I don't believe it something that the phone system is doing by itself. Is anyone in the office at night?

First turn off set relocation, and swap sets with another DN of the same model type. If the trouble follows the set, change the phone.
