Chapter 24 - Telephony Attributes Call Direction Restriction
322 Mediatrix 4104
Call Direction Restriction
You can define in which direction calls are allowed.

To set call direction restriction:
1. In the telephonyAttributesMIB , locate the telephonyAttributesIfFeaturesTable group.
2. Define the restriction on the direction of traffic in the telephonyAttributesCallDirectionRestriction
variable.
Because this variable is located in a table, you can define a different call direction for each line of
the Mediatrix 4104.
Hook Flash Processing
Hook flash processing allows hook flash signals to be transported over the IP network allowing to use
advanced telephony services. You can define how to process hook-flash detection. Users normally press the
“flash” button of the telephone during a call in progress to put this call on hold, transfer it, or even initiate a
conference call.

To define how to process hook flash:
1. In the telephonyAttributesMIB , set the telephonyAttributesHookFlashProcessing variable.
This allows the enabled subscriber services to be handled by the unit or to be delegated to a remote
party.
In the Unit Manager Network Administration Manual , refer to chapter Telephony Attributes Parameters ,
section Telephony Attributes Configuration Window .
