ext number on android

Hello. I have this question. I put an extension number for the phone number, take the link to the vcf in the admin panel, put it in the button and when downloading the vcf file on an iPhone and newer, the android opens, but on not very new ones, the phone merges with the extension like this (+78669899999134), and for me need (+78669899999,134). Open this file on the PC through the editor, where the phone is separated by a comma. If you place the qr on the page and download it like this, then everything also works correctly, but I need the card to be downloaded by clicking the button, can you tell me what could be the problem? I also tried manually, in the downloaded vcf file, put divisions for example: ( TEL: +79281591535;123 )(TEL: +79281591535\,123)(TEL: +79281591535 ext. 123)(TEL: +79281591535;ext=123) . Removes all elements and connects numbers. I will attach a link, you can download the vcf source on the “add contact” button http://neis-team.ru/anastasija-andreevna-irinarkhova/ This topic was modified 3 years, 6 months ago by magickk .

I open your vcf file in notepad and I see that your phone with ext TEL:+78633030090,144 And when I scan qrcode with any qrcode reader I see same So when you scan qrcode – scaner recognize vCard and propose add new contact When you open vcf file you open it directly in contacts app and it recognize fields in file So I see that contacts app do not know about phone ext at all.(but not scaner) According to RFC ( https://www.rfc-editor.org/rfc/rfc6350 ) you should place phone with ext like +1-555-555-5555;ext=5555 But My contacts app not recognize it too. (android 13, oxygenOS) I can`t help with that. sorry Ok, thanks for your time
