[Q] Voicemail text messages / Links

Hi,

For starters, please excuse me for the title - I really don't know how to formulate this and it might be the reason why Google couldn't help me this time.

Everyone in our team uses a Galaxy Note II - and one of them has the following problem :

When we get a text message indicating someone left us a voicemail message, we get a number of 5 to 6 digits (5555xx, where xx is the following number of that message in your mailbox). He's the only one who doesn't get that number as a touchable link that would immediately open the dialer and allow you to call that number.

I checked if it worked when you send him a text message with an actual complete phone number - and that works well. If anyone of us gets a text message with in it a succession of numbers - the numbers are always shown as link, regardless of it being a phone number or not. But not him.

I couldn't find a specific option for that in the settings. I don't think anyone of us did anything special to get that behavior.

Is this clear enough ? Can someone help with this ?

Thanks in advance.

Greetings,
Mike
