Back in the old days Telex was the most advanced form of electronic communication. But since the 80’ties and 90’ties this has been taken over by Fax and Email.
NAV still have fields for Telex No. on Customer, Vendors and Contacts, perhaps its time to send this technology to rest.
The fields are not on the UI, but still in the database.
And the same time, either modernize the current communication setup, so it could be possible to have a cell phone fields or perhaps other fields for newer forms of communication.
