BCM 50 - Strange problem with phones chirping with a short ring. ??

[GlennSexton]

After installing a new system, I started noticing that the phones would have a chirp (short ring), and one or more lines would look to be in use. I can press the line button and see that the system is accessing extension 2359 which I think is part of call pilot.
Has anyone seen this or have any suggestions?

Do you have the extensions appear and ring for any lines that you have the voice mail extension set to answer.

Ok, I made some changes. Extension 227 was mainly the one chirping so I made it App only for the lines assigned to it. Let's see if this helps. Thanks.

Sound like an auto attendant is answering the line.
