We recently migrated to a new CUCM server and upgraded from 9.X to 10.5.X... &nbsp;We've given our users access to the Self Care Portal. &nbsp;While limited in what they can do, the main feature is for them to be able to forward calls. &nbsp;The issue is it doesn't currently work without me going in and manually adding a CSS for the numbers they've forwarded under the Line settings. &nbsp;For example Call forward no answer has the number they've added in their SCP but the CSS stays at &lt;NONE&gt;. &nbsp; <br />

I've played around with the Call forward Activation Policy under Service Parameters some but can't get this to work. &nbsp;I tried &quot;with configured CSS&quot; and &quot;Activating Device Line CSS&quot;. I've been told I can edit every line using BAT.. is this the only way to achieve making Call forwarding work?

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).

Voice Over IP

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
