I have a customer with 700 phones running on CM 7.x wants to change phone configuration in 200 phones all at once just overnight . It is not like changing a DP or changing templates if it is I can use Bulk Admin Tool but these changes are significant for example if a phone has primary line and 3 more lines as shared lines when they make the change they might add a new extn as shared line and change all the existing 3 shared lines to totally different numbers. This they want to do on all 200 phones overnight is there any 3rd party tool to do this ? or what is the best way to do it?
Thanks in advance.
