SIP Trunking Between Rogers and the UCx Server

1. Introduction

This Application Note describes the steps to configure a SIP trunk between Rogers SIP Trunking Service and an E-MetroTel UCx Server.  Rogers typically provide an Ethernet connection with its own private addressing scheme to connect directly to the Rogers SIP network, which requires a second Ethernet port on the UCx to be used.  The second port must be configured to allow SIP calls to pass between the two UCx Ethernet ports.

2.     Networking Configuration

2.1    Configure the SIP Trunk

The UCx does not have a pre-configured selection for Rogers on the UCx.  In this case, we will add a SIP Trunk via the Trunks page on the PBX / PBX Configuration tab.  Select Add SIP Trunk.

On the Add SIP Trunk page, provide values for:

  • Trunk Name:
    • name you want to use to identify the trunk in UCx
  • Outbound CallerID:
    • CallerID value provided by Rogers
  • PEER Name:
    • name you want to use to identify the SIP Peer in the UCx
  • PEER Details as follows: (in our example, we have used - use the value Rogers supplies to you.
  • USER Details:
    • Delete the data in this field and leave Blank


Click on Submit Changes when done.

2.2    UCx Ethernet Configuration

The Rogers SIP Trunk service will require the use of the second Ethernet port (Ethernet 1) on the UCx. The UCx Ethernet 0 configuration will not require any changes, so details are not included in our example, although additional information on how to configure the Ethernet ports.

Configure Ethernet 1

The Ethernet 1 connection will pass SIP and media information from the Rogers connection to the UCx and the rest of the UCx connected devices on Ethernet 0.

The DNS server addressing should be configured as shown for the Rogers network.
Click Apply Changes when done.

Configure a Static Route

A static route must be created to pass SIP and media information from the Rogers connection to the rest of the UCx connected devices on Ethernet 0.

The above example tells the UCx to route all traffic with a destination address in the subnet (the Rogers SIP Trunk service IP address provided by Rogers) to the gateway IP address of, which is associated with the interface created above.

3.0 Trunking Configuration

Outbound routes should be created as per normal trunk configuration.  Refer to Outbound Routes for details.
