Avaya IP Office

Open the Avaya IP Office Configuration in Manager.

  1. Click on System, and choose which LAN interface the SIP trunk will be connecting through.  In this example we are using LAN2.
  2. Under the LAN tab, click on the VOIP sub-tab and configure the following:
    1. SIP Trunks Enable – CHECKED
      1. RTP – Port Number Range
      2. Minimum: 46750
      3. Maximum: 50750
    2. RTP – Port Number Range (NAT)
      1. Minimum: 46750
      2. Maximum: 50750

  3. Under the LAN tab, click on the Network Topology sub-tab and configure the following:
    1. STUN Server Address: BLANK  (if it is 0.0.0.0, clear the field so it is blank)
    2. Firewall/NAT Type: Unknown
      1. This may need to be configured to Open Internet or Full Cone NAT depending on the customer’s firewall
    3. Public IP Address: The public IP of the PBX
    4. Public Port
      1. UDP: 5060
      2. TCP: 5060
      3.  TLS: 5061

  4. Click on the DNS tab and configure the customer’s DNS server and backup DNS server IP addresses. We reccomend using 8.8.8.8 and 4.2.2.1

  5. On the Group pane on the left, right-click Line and select New -> SIP Line

  6. Overall, the SIP line will have a plain configuration with no need for credentials

  7. Click on the Transport tab and configure the following:
    1. ITSP Proxy Address: 52.41.52.34w1,52.8.201.128w1,50.17.48.216w1 (The w stands for "weight." This tells your PBX to round robin our IPs)
      1. Copy/paste the above into the field, as all 4 servers will be utilized
    2. Use Network Topology Info: <choose the LAN interface being used for SIP>

  8. Click the SIP URI tab and configure your channels as you would for any SIP trunk
    1. You will need one incoming channel with Local URI, Contact, and Display Name all configured as *
    2. You will need one outgoing channel with Local URI, Contact, and Display Name all configured as “Use Internal Data”

  9. Click the VoIP tab, and configure the following:
    1. Codec Selection: Custom
      1. Under Selected, make the list G.722, G.711 ULAW, in that order

      2. If these codecs are not available, you will need to configure the codec list under System, on the Codecs tab.

    2. Re-invited Supported: Checked

Configure your incoming call routes, short codes, and ARS as normal.  Once saved and rebooted, the system should now have a registered SIP trunk available for calling in and out.
