CUPC - dial-by-contact feature problem

[Dmitry Kochetkov]

Greetings!

Could you please give a piece of advice on the following issue?

When you initially add a contact to your contact list everything works fine: there's a clickable phone button in the highlighted contact. But after some time (for example after the client is relaunched) the dial-by-contact feature just disappears like in the pic. below:

Only chat is available. Anyway if you try to make a call you get the follwing error:

If you delete the contact and then add it again in a usual way, the problem disappears for a short time and then reproduces itself again.

Does anyone have an idea about the reason for that?

found out that it has sth to do with URI. If a user doesn't have URI info in the CUCM, then the above issue happens. The URI info is taken from the Active Directory -> attribute editor -> msRTCSIP-PrimaryUser should  be filled in. Any way it's just a workaround, to avoid the problem I have to manually edit that attribute for each user.
