VoIP Connection Diagram
Managed VoIP involves additional equipment on site that handles most of the VoIP switching, routing,
and call processing. Various terms and acronyms apply to Managed VoIP including SIP trunking,
Asterisk PBX, ISDN PRI, and T1 feeds. There are many types of architectures available using
particular combinations of these and other items. One sample diagram is below. If you have a
Managed VoIP system, your IT person and/or telephone switch provider should know the details.
Note: Although an Asterisk PBX is considered managed VoIP, if the VoIP gateway is the same as
the Data Gateway refer to the Hosted diagrams above.
Figure 4 - Dedicated VoIP Gateway
Refer to this diagram when your managed VoIP service employs a SIP appliance connecting a
dedicated VoIP Gateway. The SIP server/Gateway can be an Asterisk device or Telephone switch
card fed with a SIP Trunk or ISDN PRI circuit.
Remove the original connection (dotted Line). Re-route the connection carrying all VoIP traffic
through the two Vertex “VoIP Bridge Ports”. Connect the Management Port to the Network Switch.
