6.1. Avaya SBC¶

Important

Any changes to network interfaces needs to be followed by System Management → Restart Application.

6.1.1. SBC Configuration¶

Log into your Avaya SBC

Fig. 6.23 Avaya SBC Login¶

6.1.1.1. Create a SIP Recording Server¶

Navigate to Services → SIP Servers → Add. Change the Server Type to Recording Server. For encryption, select your TLS Client Profile (Create the TLS profiles under TLS Management. Please see your IT administrator if you have questions). Add the NexLog DX-Series IP address, RTP port, and transport type.

Add SIP OPTION heart beats to your SIP Recording Server.

Fig. 6.24 Add SIP Server¶

Navigate to the Advanced Tab and Enable Grooming and Tolerant.

6.1.1.2. Routing¶

Navigate to Configuration Profiles → Routing and create a route and select the SIP Recording Server from the last section.

Fig. 6.27 Create Route¶

6.1.1.3. Recording Profile¶

Select the Routing Profile created in the last section and select the Recording Type as Full Time.

Fig. 6.28 Full Time¶

6.1.1.4. Server Interworking¶

Navigate to Configuration Profiles → Server Interworking and modify your profile to support DTMF RFC 2833 Relay & SIP Notify.

6.1.1.5. Application Rules¶

Navigate to Domain Policies → Application Rules and enable Audio in and out.

Fig. 6.30 Audio¶

6.1.1.6. Media Rules¶

Navigate to Domain Policies → Media Rules and set up your Audio Encryption preferred formats. Enable interworking.

6.1.1.7. Signaling Rules¶

Navigate to Domain Policies → Signaling Rules → Add. Set a unique UCID for the Session Manager and Signaling interface.

6.1.1.8. End Point Policy Groups¶

Navigate to Domain Policies → End Point Policy Groups → Add. Set the Application Rule, Media Rule, and Signaling Rule created in the previous steps.

Fig. 6.34 End Point Policy Groups¶

6.1.1.9. End Point Flows¶

Navigate to Network & Flows → End Point Flows and Add. Create an internal and external end point depending on your infrastructure. SBC_RED_Eventide represents the internal (red side) Avaya Aura network and SBC_black_SIG represents the external (black side) network connected to the SIP Trunk. Configure the SIP Server Profile, Received Interface, Signaling Interface, Media Interface, End Point Policy Group, and Routing Profile created in the previous sections.

6.1.1.10. Session Flow¶

Navigate to Network & Flows → Session Flows → Add. Create a Session Flow for the SBC to the NexLog DX-Series.

Fig. 6.38 Add Session Flows¶

6.1.1.11. Avaya SBC Troubleshooting¶

Log into the SBC and switch to the root user via su root.

Run the command tracesbc and start capturing.

Make a call and analyze the output.

Fig. 6.39 Troubleshooting¶

In the figure above the 201.2.1.4 IP address represents the external (black side) network.

The SIP INVITE reaches the Avaya SBC and forwards the INVITE to the internal (red side) network 205.6.0.60.

The SIP INVITE is then routed to the NexLog DX-Series 200.20.23.26 on the red side.

tracesbc will automatically create a pcap to view on WireShark and a packet capture can be configured on the NexLog DX-Series.

6.1.1.11.1. Possible Scenarios¶

6.1.1.11.1.1. Scenario One¶

SIP OPTION heart beats are not reaching the NexLog DX-Series

If you do not see the SIP OPTIONS going from the external network, to the SBC, to the internal network, and the recorder, then you have a network issue. Please check your firewall rules.

6.1.1.11.1.2. Scenario Two¶

SIP OPTION heart beats are reaching the NexLog DX-Series, but no SIP INVITES/RTP is reaching the NexLog DX-Series.

The receiving, signaling, media interface, and/or the end point flow are most likely misconfigured or there is a firewall issue.

6.1.2. Recorder Configuration¶

Log in to the Configuration Manager and navigate to Recording → Recording Interfaces and select Add Virtual Recording Interface. Configure the Avaya SBC SipRec Recording template and select the proper Ethernet Device, SIPPort, Endpoint IP, and Recorder Sip Stack.

Fig. 6.41 Configure NexLog DX-Series¶

6.1.2.1. Verifying Recording¶

You should now be able to make calls to confirm that recordings are taking place between the Avaya SBC and Eventide NexLog DX-Series.

You can review actual recordings by logging into the MediaWorks DX playback interface.
