Need assistance on unexpected trunk group behaviour

Hello,

We have had many reports of users in call centers receiving calls that are just loud burst of static. When investigated, the calls callerID info was;

extension TAC: XXXX
name: %Branch Location% Inbound

This name and TAC corresponds to one of our trunk groups. The calls don't seem legitimate. I slowly removed members of the trunk group until I isolated one member being the cause. When that member is removed they do not receive these calls. When present it is VERY often. However, when I insert it into the trunk group and call the number, the quality and fidelity of the calls is excellent. Any tips or ideas on how to troubleshoot/resolve this? Thank you!
