I was actually on a conference call before and I had to put the call on hold, go over to the conference room that is just feet from my desk and ask them to please close the door - they had the door open and were extremely loud - so I could hear on the phone.
I've done a variety of these things, but since there are so many different people walking through, using the conference, etc. It is always another group so thus the repetive annoyance factor. If it was one or two groups, it wouldn't be so bad as I could speak with them and ask them to keep it down. But I have to repeatedly do us now.
And there are bad and good days. Today not so bad, but then again I have had a slew of meetings myself so I haven't been at my desk.
And I like my job (well at least I need my job in this market) and don't really want to do anything that we be a CLM.
