Before this commit the phone fields inside forms did start in a blank state. After this commit the empty phone fields are pre-filled with "+" and the country phone code. The country is determined based on the IP address with the GeoIP database. The phone code is obtained from `res.country` where it is kept in cache. task-2463563 closes odoo/odoo#78068 Signed-off-by: Romain Derie (rde) <rde@odoo.com> Co-authored-by: Benoit Socias <bso@odoo.com>
