Configuring Interactive Intelligence for DMP Plus Series VoIP

Registration

VoIP functionality within the DMP Plus Series is built around the Session Initiation Protocol (SIP) signaling system, as defined in RFC 3261. The Interactive Intelligence platform must be licensed to allow the addition of generic basic third-party SIP endpoints before any line registration can take place.
The DMP Plus Series requires that the Early Offer call initialization model be used, referred to as Normal Media Timing within Interactive Intelligence systems.
It is recommended that a static IP address is assigned to the network interface used for VoIP traffic on the DMP Plus Series.

Create a New Line

Registration of a DMP Plus Series VoIP device requires the creation of a new line within the Interaction Administrator platform. Start the application with administrator credentials.

Click on the Lines [1] item on the left-hand side of the screen.
Right-click on the right-hand list portion of the screen [2].
Select New [3].

Configuring DMP Plus Series C V (AT) VoIP Lines

VoIP configuration of the DMP Plus Series is handled exclusively through a web interface, served from the device itself. The VoIP landing page is accessed through an address of the format –
http://192.168.254.254/www/voip.html
– where 192.168.254.254 in this example is the default IP address of the DMP Plus Series device. Up to 8 lines may be configured. Note that each line intended for use will require a unique extension to be specified as part of the configuration process in Section 2.0.

Network Interface Configuration

Clicking on the Network followed by Interface tabs allows changes to be made to the desired network interface on the DMP Plus Series; either LAN1 or LAN2 may be used for VoIP. VLAN tagging is available on either interface if required. Up to two DNS entries may be manually specified. Click Apply after making any changes to restart the networking services on the device.

Transport Configuration

Click on the Transport tab to access signaling transport configuration. Set the transport to either UDP or TCP per Section 2.1. The default transport type for the DMP Plus Series is UDP.
In the event that changes need to be made, click Apply to commit any adjustments to the device.

Line Registration

Click on the first line tab to be configured as part of the system, e.g. Line 1.

User Name: Set this to match the extension number from Section 2.2. 2)
Authentication User Name: Set this field to match the extension number above.
Authentication Password: Use the extension number from (1) and (2) as the password.
Display Name: Optional. Specify an identifier for the line if required.
Primary Proxy Name/IP: Specify either the IP address or domain name of call server.
Primary Proxy Port: Specify the port number as required. The default i 5060.

Once the above settings have been entered, click the Apply button to save to the device. Click the Register button to initiate registration to the call server. If successful, the registration status to the right of the Register/Unregister buttons will indicate Registered Primary.

Codecs

The availability and priority of codecs may be changed from within the Audio tab. Codecs will only be available for use within phone calls if they are moved from the Available to the Assigned column. By default, G.711u and G.711a are assigned to the system. Codec assignment and priority can be set per line. Click the Apply button to commit any changes to the device.

Dialing

Use the Dialing tab to select the desired DTMF signaling method. The default DMP Plus Series mode is In-Band. Other available options are as follows:

Out of Band SIP INFO
Out of Band SIP INFO (RELAY)
Out of Band RFC 2833

Recommend DTMF delivery method is Out of Band RFC 2833

Click Apply after selecting Out of Band RFC 2833 DTMF signaling method for the line. This can be set per line.

System Overview

Once all required lines have been registered to the call server, use the Home tab to view a summary of the system, as required. In the example below, one of two registered lines (line 3) is currently in an active call. Appearance- specific (caller-specific) details for active calls can be accessed by clicking on the corresponding Line entry.

Troubleshooting

In the event of failure to register, review the following:

Check that the credentials specified as part of the Interactive Intelligence setup are correctly entered into the registration fields for each line.
Check network interface settings, including DNS fields (particularly if a proxy domain name is being used rather than an IP address).
Click on the Logs tab to inbound and outbound SIP transactions. The absence of inbound transactions indicates a network routing problem. Registration-specific problems may be indicated by corresponding SIP responses such as 403 Forbidden.

Appendix B: Automatic Line Re-Registration

Some call managers and networks go into maintenance windows which do not allow VoIP endpoints to register or maintain their registration. To help resolve this issue the Automatic Line Re-Registration function can be configured to re-register a line if line registration is unexpectedly lost. This function causes the VoIP interface to re-attempt a line re-registration if the first automatic re-registration attempt fails.

In order to use this feature, the line must first be registered to the call manager. Note: When enabled, this function will attempt re-registration once the SIP timer has expired. By default the SIP timer is set to 3600 seconds (60 mins). By default, the Automatic Line ReRegistration feature is disabled, with the “registration_fail_retry_count” set to zero (0).
To set up Automatic Line Re-Registration, the following steps must be carried out.

Requires Firmware 1.08.0002 or later.

Method 1 Internal Webpage

From internal webpage Select Network then Advanced Tab
To Enable the Automatic Line Re-Registration select the check box
Enter Retry Count ( 0 99) a. This is the number of attempts a Line will make to re-register i. Example below is set to twenty (20) reconnections attempts ii. If this is set to zero (0), the feature is disabled
Enter Retry Delay (120 3600 seconds) a. Amount time between registration attempts in seconds i. Example above is set to 300 seconds (5 mins) between reconnections attempts
Once Set hit Apply

Method 2 Configuration file

Create a new blank text file using a suitable basic text editor a. Example “voipConfig.conf”is attached to this PDF, see Section 3.9
Enter the following text into the document

a. This is the number of attempts a Line will make to re-register i. Example above is set to five (5) reconnections attempts ii. If this is set to zero (0), the feature is disabled iii. Valid Range of values: 0 – 99
b. registration_fail_retry_delay”:300 Amount time between registration attempts in seconds i. Example above is set to 300 seconds (5 mins) between reconnections attempts ii. Valid Range of values: 120 – 360
Save the file as voipConfig.conf.
Navigate to the VoIP configuration webpage and click on the System tab.
Under Export System Configuration, click the Export button in order to back up the current VoIP configuration to disk. The file will be saved in the default web browser download directory.
Under Import System Configuration, click the Browse button to locate the voipConfig.conf file created in steps 1 to 3.
Click the Import button to update the DMP Plus Series with the new settings. A notification will appear once the settings have applied successfully.
