Hi,<br />
<br />
I have configured a Unity Connection and a Call Manager in my lab using a SIP trunk. I can dial the voicemail pilot from any of the phones and configure the voicemail box all ok.<br />
However when I call from another phone and it sends the call to voicemail, the call goes to the &quot;hello cisco unity connection messaging system. From a touch phone telephone you may dial an extension..&quot;<br />
<br />
How do I resolve Unity Connection so it recognises that the call has been forwarded from an IP phone for the caller to leave a message. I know its simple, however I haven't setup a CUC server before so I want to learn.<br />
<br />
Thanks

Unity Connection not sending calls to Mailbox

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).
