1. Managing Wave system resources
Many Wave and third-party applications require system port DSP resources such as TAPI/WAVE ports, Fax ports, and IP telephony ports. You manage system port DSP resources via the Resource Management applet in the Global Administrator. The type and number of system ports available on your Wave Server may vary depending on which cards and modules that are installed. For information about the resources included on your Wave Server cards and modules, refer to the Wave Server Hardware Reference Guide.
Caution! You must allocate an appropriate number of resources to cover your system demand. If you under-allocate resources, calls may be lost or not handled as expected.
Determining how many system resources are required
There are two ways to determine how many and what type of system resources you need to allocate to meet your system’s requirements:
The Resource Management Advisor calculates requirements for most resource types, including:
| • | Phones |
| • | Call recording |
| • | Trunks |
| • | Conferencing |
| • | Music On Hold |
| • | Voice Mail |
| • | Call Volume |
| • | Contact Center |
| • | Fax Manager |
If you need to support additional applications or features (see System resource types), you must identify the required resource types and then manually calculate and allocate the number of each type that you require to support your needs.
| • | Manually calculate the resources of each type that you require to meet your needs (see System resource types) , factoring in both the hardware and Wave licenses installed on your Wave Server, as well as other system resource limits described in System resource assignment limits. (Note that the installed hardware, licenses, and resource limits are factored in automatically if you use the Resource Management Advisor.) |
Resource requirements for transitory events
Some Voice Over IP DSP resources are used only briefly during the life a of a call or while a feature is being used. To avoid problems (such as no ring back on calls), you must allocate sufficient Voice Over IP DSP resources so that additional resources are available beyond the number required to support the total concurrent IP calls that you require.
Important! In this version, you must allocate these additional resources manually, even if you are using the Resource Manager Advisor—the current resource calculation algorithm used by the Resource Manager Advisor does not allocate them automatically.
Additional Voice Over IP DSP resource will be required in the following call scenarios.
| • | When all digits are not dialed before placing a call from a SIP phone, an additional DSP resource will be required to apply fast busy tone in case of an inter-digit timeout or call failure, or to apply ringback tone on a successful call. |
| • | When a VoIP call is placed using Viewpoint, an additional DSP resource will be required to apply ringback tone on a successful call. |
| • | For any feature invoked from a SIP phone either via a Feature button or by pressing Flash followed by a * code, an additional DSP resource will be required to apply dial or stutter dial tone. |
| • | When a SIP Phone or SIP trunk is involved in a blind transfer, an additional DSP resource will be required to apply ringback tone. |
Using Resource Management and Resource Management Advisor
To add, change, or remove system resources
| 1 | If necessary, click the Administration tab of the Management Console. |
| 2 | Click Resource Management, located in the PBX Administration section. |
When you start the Resource Management applet, the following message is displayed to remind you to schedule your updates carefully to avoid disrupting your phone service:
Click OK to continue.
| 3 | When the Resource Management applet opens, expand any of the groups in the left pane to view the resource types in that group. |
The number in parentheses next to a resource type indicates the number of resources currently allocated.
The Available Resources section at the bottom of the dialog shows the number of ports and MCPS (DSP cycles) available. Some resources consume more MCPS than others, so watch both numbers as you change resource allocations. For a description of each resource type, see the table in System resource types.
| 4 | Do one of the following: |
| • | If you want Wave to automatically calculate the resources you require, click Resource Management Advisor. |
| • | If you already know how many resources you want to allocate, go to step 8. |
| 5 | The Resource Management Advisor starts. |
Answer all of the questions. and then click OK.
Note the following:
| • | You must answer every question. |
| • | If the answer to a question is zero, enter “0”—do not leave any answer box blank. |
| • | Based on your answers, the cards, modules, and Wave licenses installed on your Wave Server, as well as other system resource limits, you may see one or more error messages like the following. If you do, go back and enter a lower value for that question and click OK again to recalculate: |
| 6 | When the number of resources required has been successfully calculated, the results are displayed: |
Once you click OK, the dialog will close and the information will be lost. To retain the information, do one of the following:
| • | Make a note of the information or capture a screenshot of the Results dialog before clicking OK. |
| • | Leave the Results dialog open and press Alt-Tab as needed to bring the dialog forward again as you allocate the resources. |
| • | Resize the dialogs so that they are open side by side while you allocate the resources. |
Make a note of the information in the Results dialog before clicking OK, which will close the window. Or, leave the window open and press Alt-Tab as needed to bring the Results dialog forward again as you allocate the resources.
| 7 | Click OK in the Resource Management Advisor to return to the Resource Management applet. |
| 8 | Click an item in the left pane to adjust the number of resources allocated to it in the right pane. The Available Resources section at the bottom of the dialog shows the number of ports and MCPS (DSP cycles) available. Some resources consume more MCPS than others, so watch both numbers as you change resource allocations. For a description of each resource type, see the table in System resource types. |
| 9 | Click Done when you are finished. |
The following table describes the various resources listed in the Resource Management applet.

Prompt Assist. Used to provide IVR functionality to users, for example auto attendants, phone command menu on analog phones, prompts and calls handled via a personal routing list, Contact Center queues, and so forth. |
|||||||||||||
|
You can allocate either of the following resource types to support voice mail access. These two resource types are mutually exclusive, so all voice mail resources must be assigned to one option or the other. |
|||||||||||||
|
|
Voice Mail Dedicated Pool. Used for voicemail access, either a caller leaving a voice message or a user playing back a voice message. |
||||||||||||
|
Voice Mail w/Automatic Gain Control. Same as the previous resource type, but also provides automatic gain control (AGC) for voice mail recordings. (AGC adjusts the volume level of audio as a voice message is recorded so that the playback level is more consistent.). |

Service Response |
Used for sessions of the separate Service Response application. See the documentation included with Service Response for more information about how to use these resource types. |

System resource assignment limits
The Resource Management applet enforces limits on the number of resources that can be assigned to each application.
| • | Voice Over IP. Purchased software licenses allow you to use the DSPs available on the Wave Integrated Services Card for IP telephony. |
| • | Voice Mail. Limited by sub-group. |
| • | Call Navigator. For system resource assignment limits for this application, please see the Wave Call Navigator Administrator Guide for more information. |
| • | Third Party Applications. Limited to 100 ports. |
| • | Music On Hold. 8 ports maximum. |
| • | Service Response. For system resource assignment limits for this application, please see its accompanying documentation for more information. |
| • | Voice Server. For system resource assignment limits for this application, please see its accompanying documentation for more information. |
Note: Some resources are restricted by licenses. If a category requires a license, such as Call Navigator, you will not be able to assign any resources to it until you have entered a valid license key in the Software Licenses applet. See About Wave licenses
for more information.
