IP Traffic Management, also called Call Admission Control, allows you to configure the number of simultaneous calls that can be active between a network element (any configured IMG, external gateway, or external gatekeeper) and an IMG. IP traffic limits are applied to the combined total of incoming and outgoing calls.

The following is an example of what would appear in the call trace for every call to or from a gateway under IP restrictions.
CALL> 16:16:48.480 CALL(L4) (00:7040:01) IP Traffic Management: Resource Group ID: 2 583 Busy Count: 55 Channels Allowed: 300
SIP - If a SIP call is rejected because the maximum number of calls is reached, the IMG will send a 503 response.
H.323 - If an H.323 call is rejected because the maximum number of calls is reached, the IMG will send a cause code of 34 - No Circuits Available.
The IMG upon which the traffic restrictions will be applied. When set to ‘All IMGs’ the restricted Network Element will be allowed the Maximum number of sessions to each IMG node.
The External Gateway upon which the traffic restrictions will be applied. This field is a drop-down list of all the configured External Gateways.
This is the maximum number of calls that can be active at any one time between the designated network element and the IMG, in either direction.
