Avaya Aura Session Manager configuration for Vocia MS-1

The BiampVocia Message Server (MS-1) includes functionality to allow pages to be initiated over VoIP system that adhere to the Session Initiation Protocol (SIP) standard. This functionality is obtained by configuring a SIP Trunk between the two systems. This document details the steps required to configure a SIP Trunk in Avaya Session Manager to interface with the Biamp Vocia MS-1.

Avaya system verification

This section describes the steps needed to verify Communication Manager can route and receive calls over the SIP trunk to Session Manager to support calls between Session Manager and the Vocia MS-1. If any part of this verification is found to not be in place, the SIP Trunk connection between Communication Manager and Session Manager must be established before moving on. Contact the Avaya system Admin or Avaya Tech Support for further information on enabling these features.

Verifying trunk capacity

  1. Log into Avaya Communications Manager.
  2. In the Administration menu, choose the Native Configuration Manager.
  3. Log into Native Configuration Manager.
  4. In the command line, type: display system-parameters customeroptions
  5. Navigate to Page 2.
  6. Ensure that the Maximum Administered SIP Trunks allowed total is greater than the used total. (Figure 1)

 A note about Digit Conversion

The MS-1 requires a single user name to be provided in the “from” address in the SIP header. To facilitate this, the Avaya system can be configured to modify the SIP origination field of the SIP Header for any call placed through the trunk line. Here is a basic overview of the required Digit Conversion options listed in Figure 5 on the next topic.

  • Matching pattern: Defines the portion of the original extension that will used to match the digit conversion. Typically this will be setup to cover a large number of extensions. It is required for every phone extension that will support paging functionality, possibly wide enough to cover every phone in the system. The Figure 5 example has been setup to provide paging from (10) seven digit extensions; 6000000-6000009. The matching number in this case is 600000(x) with x left undefined.
  • Min / Max: In the Figure 5 example case the extensions are always 7 digits in length. The example rules indicate that the Min and Max are both 7, meaning that any extension would need to be exactly 7 digits wide to proceed. Min and Max settings could be expanded to extend the wildcard range to cover more extensions.
  • Delete Digits: This defines the number of digits that will be removed from the original extension in the SIP Header. The MS-1 supports a single user name so all digits must be replaced. In the Figure 5 example shown, all 7 digits are slated for re-write.
  • Insert Digits: This field defines the digits that will be inserted into the re-written SIP header. In the Figure 5 example the Insert Digits field is set to 7777777. The MS-1 User Name would also be 7777777.

Digit Conversion

  1. Proceed to the Digit Conversion for Outgoing Calls from SM section of the Adaptations page and click add (Figure 5).
  2. Specify the Matching Pattern, Min/Max settings, Delete Digits, & Insert Digits fields based off of the unique settings in the phone system. Note that the Insert Digits field must match the SIP User Name entry of the MS-1.
  3. Change the Address to modify setting to Origination. PLEASE NOTE: This field may need to be set to Both instead of Origination.
  4. Repeat steps 8-9 for any additional conversion patterns that need to be put into place.
  5. Click Commit.
