ok... so that doesn't help, or I am confused........? &nbsp;My question is how to do create a PLAR from a phone on a switchport? &nbsp;How do you create a hotline/direct auto-dial phone from say a 7975 to another phone, a 504...?

I just installed a UC560, ESW-540 switches and phones. &nbsp;I have a need for a hotline in my lobby, pick up the handset and it only dials extension 7555. &nbsp;Is there a way in the CCA to configure this? &nbsp;If not, can someone assist with the CLI commands? &nbsp;TIA!

Create a ringdown using CCA on the UC500?

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
