Hello, Here is a typical Outbound dial plan that we use. condition destination_number ^(\d{10})$ action set sip_h_X-accountcode=${accountcode} action set sip_h_X-Tag= action set call_direction=outbound action set hangup_after_bridge=true action set effective_caller_id_name=${outbound_caller_id_name} action set effective_caller_id_number=${outbound_caller_id_number} action set inherit_codec=true action bridge sofia/gateway/domain.com-GWname/99900$1 Things work perfect however if our client is using one of the VOIP desk phone such as Polycom IP33x or Grandstream GXP21xx, the display will show the number dialed but with the prefix which the client has no clue how of it is it. The problem is magnified when he is trying to go through the call history, the Polycom will show the dialed number with the prefix which will prevent him from dial back. The grand stream is not as bad as if you go to the call hisptry it will show what was dialed only. Is there a way to not show the prefix in the phone's display although it goes out with each number dialed. Thanks, George
