vCard backup contains deprecated type ISDN
Backup file .vault/People/data/all.vcf
of contacts created with People app contain deprecated telefon type ISDN:
TEL;TYPE=ISDN,HOME:1234
TEL;TYPE=ISDN,WORK:5678
Type ISDN is not found in RFC6350 anymore.
ISDN is still available (ISDN is specified by ITU standards not RFCs; RFC 6350 only specifies "predefined types" , see section 6.4.1 "TEL"). So it is not wrong having type ISDN in vCard sets. (Question is, whether other databases can make use of such type. And, accepted, I do not see any sensible reason for that type to be differentiated from the predefined types – but that's another question.)

axaq ( 2014-02-10 03:35:29 +0200 )editWhat version does the .vcf file indicate? 3.0 or 4.0? Version 3.0 would refer to the older RFC 2426. Anyway, replacing VOICE with ISDN seems strange to me, too. I see no reason to use ISDN.

I just started reading about vCard RFCs yesterday. That's why I tagged this question with "enhancement" :-)
My problem with ISDN is that imported vCards get changed when edited.
I don't know if other tools would have problems importing vCards with ISDN telephone type. Haven't tried sending vCards to other phones via Bluetooth or so.
