I have noticed that vCards in Jive Messenger do not distinguish between certain types of information.
There is only 1 set of address and phone number information.
This is not noticeable in some clients, such as Psi, which are the same.
But with other clients using the full JEP-0054: vcard-temp specification, such as Exodus, the vCard information gets scrambled.
In the specification you can store and retrieve 2 sets of address information, for home and work.
Also, you can store and retrieve phone numbers for voice and fax, for both home and work.
I am using Jive Messenger 2.1.3, using the Embedded-DB.
It would be nice if you could store more information in the vCards.
