Configuring DN Objects
You configure Genesys DN objects to represent CUCM in the Configuration Layer under the Switch object that is assigned to the appropriate SIP Server.
For each CUCM SIP Trunk present in the cluster, create a DN object of type Voice over IP Service. Configure the following options in the TServer section for such object.
| Option Name | Option Value | Description |
|---|---|---|
| contact | SIP URI | Specify the contact URI that SIP Server uses for communication with CUCM. |
| dual-dialog-enabled | false | Set this option to false to instruct SIP Server not to create new a SIP dialog when making a consultation call. |
| enable-agentlogin-presence | true | Set this option to true for SIP Server to provide accurate information about agent states. |
| make-call-rfc3725-flow | 1 | Set this option to 1, so SIP Server selects the SIP call flow number 1 (described in RFC 3725) for a call that is initiated by a TMakeCall request. |
| oos-check | Specify how often (in seconds) SIP Server checks a device for out-of-service status. | |
| oos-force | Specify the time interval (in seconds) that SIP Server waits before placing a device that does not respond in out-of-service state when the oos-check option is enabled. | |
| refer-enabled | false | Set this option to false for SIP Server to use a re-INVITE request method when contacting CUCM. |
| service-type | softswitch | Set this option to softswitch. |
Create a DN of type Trunk with the name, for example, CUCMTrunk. Create a section that is named TServer. In the TServer section, create options as specified in the following table.
| Option Name | Option Value | Description |
|---|---|---|
| contact | SIP URI | Specify the contact URI that SIP Server uses for communication with CUCM. If there is a cluster CUCM deployment, specify the address of any CUCM. |
| contact-backup | SIP URI | (For CUCM cluster only) May contain a comma-separated list of addresses of other members of the CUCM cluster. In case of a single node CUCM deployment, this option must not be configured. |
| oos-check | Specify how often (in seconds) SIP Server checks a device for out-of-service status. | |
| oos-force | Specify the time interval (in seconds) that SIP Server waits before placing a device that does not respond in out-of-service state when the oos-check option is enabled. | |
| subscribe-presence-domain | Any valid domain | Specify the subscription domain information for the Trunk DN. This option value is used with the DN name to form the SUBSCRIBE request URI and the To header. |
| subscribe-presence-from | SIP URI | Specify the subscription endpoint information. This option value is used to form the From header in the SUBSCRIBE request to CUCM. This must be the same address as the SIP Server host that is part of the SIP trunk configuration in CUCM. |
| subscribe-presence-expire | Specify the subscription renewal interval (in seconds). |
Enable a presence subscription for the Extension DNs by specifying the option subscribe-presence. This option's value must be the name of the Trunk DN that contains subscription parameters—for example, CUCMTrunk.
Extension DN objects...
- ...must not have any other options configured.
- ...must not have the option contact configured.
- ...must be created for all DNs used as agent phones.
Create Agent IDs for all Extension DNs with the subscription enabled. The Agent ID must be same as the ID of the DN of type Extension.
