The Dial Plan Transparency feature automatically completes calls to a called party during an enterprise network outage.
Communication Manager-DPT
Communication Manager uses the Dial Plan Transparency feature to route calls over a public network when calls cannot be routed over the IP network. The called party or the calling party may not be aware of the network outage situation. For the Communication Manager-DPT (CM-DPT) to work, the same Communication Manager must serve the calling and the called endpoints. To activate CM-DPT, users do not need to change the dialing pattern.
Note:
  • The call must be a direct call to the endpoint and not a redirected or a forwarded call.
  • CM-DPT is not triggered during a network outage if there are any group features, such as hunt groups, associated with the call.
Session Manager-DPT
For Session Manager Dial Plan Transparency (SM-DPT) to work, the calling party must be using SIP endpoints, but the called party can use any type of endpoints. The calling and the called endpoints must reside on different Communication Manager servers. Use the SMGR interface to configure SM-DPT on Session Manager and on Communication Manager. You can configure SM-DPT and decide the DPT routing option for each SIP endpoint location.
Note:
  • The call can be a direct call, a redirected call, or a forwarded call.
  • SM-DPT is not triggered if there are any group features associated with the call.
