If you want comfort to send SMS and call your phone then you must set both SMS and voice phone types
For sending SMS to comfort you need to have the phone number either one of the Teo phone types as one of the 8 numbers
Unfortunately It is not as simple as adding anther checkbox to comfigurator
The system has been designed as 1 phone number with 1 phone type (voice, CMS, SMS etc)
There are 8 phone numbers with phone type which can be assigned
If one phone number can be assigned many phone types as you suggest then it will will require a big change to the firmware. The voice menu is also involved as that would have to allow you to select different phone types for each phone
The data structure in the eeprom wll have to be overhauled
Hence it would be simpler to keep using 2 slots for phone and SMS especially as there are 8 phone numbers which should be more than enough for everyone.
