SCCP IP Phone Extension 2001

A user is going through a series of dialing steps on a SIP Type B IP phone (for example, a Cisco 7975) to call an SCCP IP phone.

Cisco Type B SIP Phones offer functionality based SIP INVITE Message.

Every key the end user presses triggers an individual SIP message.

The first event is communicated with a SIP INVITE, but subsequent messages use SIP NOTIFY messages.

The SIP NOTIFY messages send KPML events corresponding to any buttons or soft keys pressed by the user.

Cisco Type B SIP IP Phones with SIP dial rules operate in the same manner as Cisco Type A phones with dial rules.
