Description: This object contains an enumerated value that indicates whether the call originated locally or remotely.

What is cmmCallOrigin?

This read-only value indicates whether the current call on this modem was initiated locally, by this device dialing out, or remotely, by this device answering an incoming call. Admins use this to distinguish inbound from outbound sessions when reviewing call activity or troubleshooting directional connectivity issues. For example, if outbound calls are failing but inbound calls succeed, an admin filtering active sessions by cmmCallOrigin would quickly confirm the pattern by seeing only answer-type calls present.

Examples

Walk all instances (SNMPv2c):
