I have a BUNCH of contacts that have multiple phone numbers. For example, one contact has 3 different office numbers (because he works out of three diff offices).

I used to have a Palm Treo and had a third party app that I used to manage phone calls. When dialing with this app, it totally ignored everything after a colon.

So John Smith's contact info looked something like this:

Work - 573.555.1234:JC Office
Work2 - 573.666.1234:CLMB Office
Work 3 - 573.333.1234:Ham Office

Now that I'm on a Tour 9630, I changed the colons to pauses. When I call such a contact, they hear tones in their ear representing the letters that I've used for comments.

In addition, when such a contact calls from one of these phones, my BB sees the caller ID without the "comments" and doesn't recognize that it's the same number.

Even if it takes a third party app to do it, I'd like to find a way to have part of the phone number ignored (treated as a comment).

TIA!

EDIT: I forgot to mention that my Tour has BBOS 5.0.0.732.

You can't do that.

Create separate contacts.

That really is a horrible way to mange your contacts.
Create additional Contract entries for that individual
