Conference Fast Dialer

This app allows to create complex schemes of numbers, DTMF codes, pauses, etc. to connect easily and quickly to various conference or call systems like BT conference, Skype to Go, and whatever service support connecting via DTMF codes.
You can set up a Service to create the pattern of your conference system (i.e. call number + wait the line + digit your code + digit #). Adding a placeholder will allow you to fill it with your specific number while dialing (i.e. calling a conference system Service, you can set up the Service once and then fill the proper participant code while dialing).

Phone management permission is required to initiate phone calls for you (and to read Phone Log of recent calls)
Read Contacts permission is required to build your DTMF scheme from contact phone numbers.
Read Calendar permission is required to build your DTMF scheme from calendar events descriptions (i.e. conference systems codes)
Phone management permission is required to build your DTMF scheme from Phone Log.

Allows backup/restore of database in phone storage (a supporting app able to write files to storage is required, like ES File Explorer) or cloud services like Google Drive, One Drive. Dropbox, Box are supported in backup, but not for direct restore (but user can always save backup to storage phone and restore it from there).
