## Call Interaction

The user can make and receive calls when in a Web browser session.

When users re-enter the Web browser application, they are returned to the same point at which they left. If the user is entering text and leaves the Web browser using the Phone button, the user returns to the same state of text entry upon reentering the Web application.

No dialing is supported when in text entry mode. On-hook keypad dialing to make a phone call is not allowed when the user is entering text. Text entry is allowed while the user is off-hook. When the phone is placed once again on-hook, text entry can be re-enabled at the point where it was disabled.

When text editing is active, the user can be active on a call or receive a call, but cannot use the keypad to dial a phone number or for interactive voice recognition (IVR) prompts. The user must disable text entry prior to using keypad dialing to make a call or for IVR prompts.
