As of version 1.5.1 myPhoneDesktop provides an extended recognition for phone numbers to allow support for some GSM codes in the form #<GSM_Code>#<phone_number> (e.g. #31#+1-212-555-1212) see http://linux.sgms-centre.com/misc/gsm_codes/ for more details on GSM codes
However, due to restrictions imposed by Apple, an iPhone's Phone application would not autodial numbers that contains the * or # characters. When the user clicks the "Call" button on myPhoneDesktop for the number with a GSM Code like #31#+1-212-555-1212 then such number would not be autodialed. The number will be copied into the iPhone clipboard. The user will have to open the Phone application and paste the number before making a call.
