Although ISDN30 lines can support up to 30 simultaneous channels, you do not need to provide every single device with the same phone number.
Instead, you can get independent numbers for different devices, which make it easier for those calling your company to get through to the right person.
This is not only convenient and efficient, but makes it easier to market your company through a variety of mediums if you have inbound DDI (direct dial-in) numbers that are suited to the task of attracting business.
As with any ISDN platform, it is possible to expand most packages further to include more lines and up the amount of bandwidth which is available to your business. This flexibility means that most firms will find ISDN30 lines to be a good solution in the short term as well as going forward when circumstances start to change.
