Thank you for the prompt reply. I have added a blank space in the strip dial characters, which are now ".-() []{}." One of my contacts has a number that has a space following the area code (which is surrounded by parentheses. Calling the number results in: nnn nnnnnnn (with the space still following the area code.
Dialing with the space after the area code worked fine until I updated to 5.2.16 for Windows 32bit. Is it an option to fall back to the prior release?
Zoiper for iOS still handles the space after the area code with no problem.
