I currently have both an IAD2421 owned and managed by XO Communication and a Cisco 2821. I am going to be upgrading to the PRI package that XO offers and they claim that I will need to get a &quot;card&quot; for my router. That is all they can tell me. The IAD will have a T1 (PBX) Digital Voice Port. This is where I will grab the PRI services off of into the 2821 if I can ever figure out what kind of card I need to get. I will have 17 channels (or trunks) and the 2821 will not be doing any Internet data services at all just VoIP services for CallManager. <br />
<br />
PLEASE HELP!!!!! <br />
<br />
Since no one can seem to answer this question I have given 500 points to the person that has the answer. Many thanks!

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).
