I'm going to take a wild shot here and hope that I hit something. Are you sure that this port is extension 108? It could have been changed to something else. While unlikely, you may be making programming changes to a non-existent extension number, while the one you're working with is something unexpected, like 208. The system will let you program an unused port, but you may think you're changing the COS, etc. for the phone on this port, but you aren't. Again, I'm just throwing this out there. Sorry for the late response.

If you figure it out, or more importantly, if the information we've given you here helped you resolve it, please let us know by posting your results. We aren't looking for accolades, but a web search by someone else in the future with the same problem might land them here on this thread. Thanks in advance.
