There are new dialup numbers for LSNet.
Go to http://ls.net/callfind.pl and enter the number you will be dialing from.
You may get more than one number. Write down the last 7 digits ignoring the are code which should match yours. One may work better than others. Elk Creek and Independence use Mouth of Wilson phone numbers
There are multiple ways of finding the dialup number and they differ among versions of Windows. In recent versions,
Start > Control Panel > Network and Sharing Center > Change Adapter Settings > Dial-up Connection > Dial-up Connection Properties > Phone Number
Enter only the 7 digit access phone number.
Click OK and test your connection.
The old numbers will stop working June 12, 2014.
Some Local Exchange Carriers (LEC) off a feature known as ELCA - extended local calling area. If you have any doubt that the new number is in your local calling area not extended local calling area, call your LEC (Such as CenturyLink, Verizon, etc.).
