Thank you very much for the detailed answer, please accept my appologies for the late reply. &nbsp;I'm going to look into your system speed dial theory and do some testing. &nbsp; I'll report back in a couple days. &nbsp;Once again thank you very much for your insight!!

We have a 3com nbx 3000 that is our main system that is connected to a secondary Mitel 3300 via PRI. &nbsp;<br />
<br />
Extensions that are on the mitel are set in the dialplan of the NBX to route to the Mitel.<br />
<br />
The issue I am having is that when I want to restrict a phone on the Mitel to only dial internal extensions, it doesn't consider the extensions on the 3com as this, therefore they are denied.<br />
<br />
Is there a way to setup a class of restrictions that uses a list of extensions as exceptions? or is there something i'm missing that needs to be added to allow the mitel access to the extensions that are across the PRI.

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.
