Implementing New Extensions

[scooter817]

Hi Everyone

A friend of mine just took a job at a loan comany and he has been tasked with redoing the dial plan. Currenly the locations are using 4 digit, 5 digit and 6 digit extensions. The management wants everyone to be on the same dial plan and move to 6 digit extensions.What is the easiest way to get all the phones with the 4 and 5 digit extension updated with there new 6 digit extension.

BAT export, modify, BAT update OR AXL

Thanks for the reply Jamie, I wanted to make sure that I'm correct when I tell him this. So what he needs to do is go to Bulk Administration then go to import/export and then export. Then once there I pick the device data section and then I pick the phone option.

Yes but it’s important to understand that BAT can not modify the extension of an existing database row. In other words, when the BAT Insert Phones with Overwrite Existing Config job runs it will be creating new sIx-digit DNs associated to the phone. They will need to delete/cleanup the old four- or five-digit DN separately.

Another approach is to use this third-party Java tool to modify the existing DB records in-place.

I have used it several times and it has worked great; however, it comes with no warranty/support and is definitely NOT supported by TAC.
