Hi Marc,

• Please follow the steps in this doc to create a custom device template.
• You can refer to this knowledge base article to learn how to find the device identifier (sysOID) using MIB browser.
• You can also refer to this doc of Dialogic to obtain the OIDs for creating custom performance counters and tabular performance counters. You can also download the MIB file for future reference and testing from the Dialogic's page mention here.

Hope this helps.

Thanks,

Santhi.
