Stripping "+" sign from From and Contact fields

Hi!

I need to delete plus sign from From and Contact fields.

What is correct way to do it?

I tried to do it using session translation, but all that I've done - plus disappears from From field only.

I tried to write HMR but it is incorrect symbols:

type                                    uri-user

                        action                                  replace

                        match-val-type                          any

                        comparison-type                         pattern-rule

                        match-value                             ^+(.+)

                        new-value                               $1

Any thoughts?
