Contacts created from CTI as type "Company" are displayed with the name "-" both in CTI and in the NethVoice mobile app.

Steps to reproduce

1. From CTI, create a new contact.
2. Set the contact type to "Company".
3. Fill in the "Company" field.
4. Fill in the "Work phone" field.
5. Save the contact and check it in CTI and in the NethVoice mobile app.
