### Steps to reproduce
1. Setup nextcloud account
2. Sync SMS
3. Only carrier numbers are synced
### Expected behaviour
Google voice is setup on my phone as the main SMS and call number. I rarely give out my carrier number or receive texts that way. The app would be much more useful if Google voice SMS through the phone was also sync'd.
### Actual behaviour
SMS via Google voice number is ignored.
