Gayble,
So, what you are saying is that, Live Support through things such as PHP Live, or even AIM, Yahoo, MSN, ICQ and whoever else has an IM client should only be used for Sales?
I tend to be on-line with one of the IM clients at least a few times a day and sometimes my clients have simple questions, and I can answer them.
I do see your point though, since I have others checking the ticket system, and sometimes the clients expect to see me on-line all the time, and never open a ticket. At certain times they act if I disappeared and I always have to tell them, did you open a ticket? That system is monitored 24 hours a day.
I can see how IM may interfere sometimes. I suppose when I look at it from an angle that wherever I have hosted, I have not exactly had IM communications with them, I just open a support ticket.
