I actually prefer to place orders for my customers. I spend time with the customer first then I make the call from their location. One example of why I prefer to do it is: I just finished installing a nice system with multiple user mailboxes, AA and all other bells and whistles. I let the customer place the order for lines. In her communication with the providor she purchased Voice Mail for each line and also purchased the "Inhouse" wiring protection plan and didn't discuss any rollover or hunt group combinations.

My tip for placing orders:
Get a cup of coffee
Use speaker phone until you speak with a person
Have a list of your needs and check them off 1 by 1

I also consider it an assett to place orders via email...My Bellsouth contact is super at this

I guess I'm old fashioned..Too many cooks spoil the broth.
