Taken from the TMS online help, as well as located in the TMS admin guide as well....
You can set up the File Based Phone Book source to use for exporting phone book contacts to a file on a directory on your Cisco TMS server or another web server. Cisco TMS will then create a tab delimited file.
- Create a phone book .
- Click Connect for this phone book.
- Select the sources you want to export contacts from.
- For Update Type for these sources, select either Import to Cisco TMS or Import to Cisco TMS and Export to phone book source.
- Now select the File Based Phone Book source you want to export to.
- For Update Type for this source, select Import to Cisco TMS and Export to Phone Books Source.
There is also a few discussion on this already in the forums, here is one in particular.
