Brief Description of Traffic Flows for Strategic Partners
• All SIP traffic from Strategic Partners (SP) enter the ImOn Voice network
through one of two Session Border Controllers (SBC) located in Marion or
Cedar Falls. At present each SP is assigned to one SBC or the other. Our 2023
plan will relocate the SBC in Cedar Falls to our Iowa City Data Center and
provide Geo-Redundancy for all Strategic Partners and upstream providers.
• All PSTN trunking (TDM or SIP) must terminate to an ImOn SBC or Universal
Media Gateway (UMG). This is done by ImOn and Strategic Partners do not
need to establish trunking to any other provider.
• Strategic Partners are responsible for their internal voice networks and may or
may not chose to install, manage and maintain an SBC on the edge of their
network.
• ImOn currently supports G.711 and G.729. Default QoS settings are DSCP 46
for media and DSCP 24 for signaling.

The interconnection from Waterloo to the CFU Core Network (red) is the only new
connection required to establish full connectivity. The Layer 2 Vlan ID would be
negotiated between CFU and Waterloo while the Layer 3 addressing and routing
would be negotiated with the ImOn Engineers.Voice CoreImOn
