This read-write VismFaxDeJitterMode object specifies the de-jitter mode used for fax upspeed, applicable only to VoIP applications. Fax transmissions are highly sensitive to timing jitter, so selecting the right de-jitter strategy here is important for reliable fax delivery over a packet network. For example, an admin troubleshooting frequent fax transmission failures over a jittery IP path would review vismFaxDeJitterMode to ensure an appropriate de-jitter strategy is selected for that path's characteristics.
