Chapter 1 - Introduction and Description
If you want a user to be able to call into a facility and then use the local phone capability to dial out to
the public phone network, you can choose either the FXO or E&M interface. If you chose the FXO
interface, you can connect to the station side of your phone switch and be able to use all the features
of your local phone system. If you want to call out on the local phone network while you are at a
remote branch office, you would dial the MultiVOIP at the corporate facility and then dial an outside
line to access the local phone network.
If you use the E&M interface, you have more control over call management. The E&M connection
uses the trunk side of the phone switch; therefore, to access a trunk line, you would dial the trunk’s
access number instead of an extension number. Also, the E&M interface has five signaling types that
are supported by the MultiVOIP.
Once you have mapped out your phone and Internet/Intranet connections, you can build your VOIP
phone directory database that connects your MultiVOIPs together. From the phone directory
database you can construct a VOIP phone book and a VOIP dialing directory. One phone directory
database is all that is needed for a VOIP network. This database can be built at one site and then
distributed to other sites. The database ties the voice/fax channels to phone equipment and the
ethernet port to your local area network.
