My Customer have a Solution with CallManager 02 Servers version 5.1.3 and Gateway H.323 and is with following problem:
The user have a directory number for example 1000 and He dial to celular phone, after complete the call he put the phone in hold and to do another call to another celular phone and transfer the call. When He turn off the Directory number the user Celular A continues speaking user Celular B, He continues buy the call and the gateway stayed the channel busy. My question is: It is possible block the transfer to Celular Phone when the call is originate the IP Phone?
In CallManager, there is a service parameter (Block OffNet to OffNet Transfer Service Parameter) that should help you on this. Read this chapter that will help you to understand
Hope to help, if it does please rate.
