Can I receive two phone calls simultaneously? more
Your smartphone/PDA phone is capable of conference (multi-party) calling. However, before using the conference call feature, contact your wireless service provider to confirm if they provide such service.
  1. Select a contact from the Contact list, then tap Menu > Edit.
  2. Insert p plus the extension number after the contact's work telephone number (example: 11111111p2222), then tap OK.
You may now directly call the phone and extension number of the contact.
