OfficeServ 7100 SPECIAL APPLICATIONS
TECHNICAL MANUAL PART 2 JANUARY 2009
In the above example the station caller will hear a second dial tone when 80 is dialed.
After dialing 0 and station number 201 the MGI program looks up the corresponding IP
address with the access code 0. IP communications are established between the
MP10/MP10a of the originating system and the far end MP10/MP10a. The access code
0 is deleted then the digits 201 are sent in an IP packet and repeated by the far end
MGI. The caller will hear station ringback tone and is able to converse when the called
party answers. The access code can also be imbedded in the sent digit string
information allowing more transparent dialing.
This concept is used only when using the MGI as a trunking gateway. IP Networking
uses the communications between MP10/MP10a cards to determine the MGI use so
trunking gateway inputs are not required.

Internet Protocol (IP) Addressing

To program the MGI VoIP it must be known where to route IP based calls. A basic
knowledge of Internet Protocol (IP) networking should be understood to program IP
addresses and IP gateway addressing. The OfficeServ 7100 must have an IP address
associated with the MP10/MP10a and each MGI-16 card installed. This is the same
address if using the on-board MGI channels. The MGI cards can be programmed only
after installed in the system. The IP address can match the existing LAN (Local Area
Network) addressing scheme or it can be a totally different IP address level. It is
suggested to match the existing LAN IP address plan to permit ease of administration.
Also required will be an IP subnet mask and a gateway address.
Subnet addresses allow connectivity in the same network and determines if the data
needs be forwarded to a router.
Gateway is a term used as a junctor or the meeting point of two networks. This meeting
point can be a router or an MGI card. When a request is made by a PC or other IP
device (MP10/MP10a or MGI) and the address is not in the local network the gateway
IP address is where the next search is performed. The gateway then looks outside the
local network for a response to the request. This all happens within milliseconds. Once
a response is obtained, the LAN gateway router acts as the bridge between the two
networks. The information can be strictly data or it can be voice data. In the OfficeServ
7100 MP10/MP10a and MGI, programming the gateway is equivalent to the router
address to leave the local LAN and access another network.

ITP Keyphones and IP Network Connectivity

The OfficeServ 7100 MGI cards provide a proprietary gateway between the ITP
keyphones and the system features and services. The connections between networks
should be understood before requesting or installing the services for local or remote
location ITP keyphones.
