In some cases, employees should not see the actual phone number of a client. Here is a possible approach to solving this problem: employees will be provided with an alternative number that they can use to call back.
Go to System → System File Customization.
Open the modules.conf configuration file for editing. Set the mode to "Add to end of file".
Connect the module to calculate the hash sum:
load => func_md5.so
Open the extensions.conf configuration file for editing. Set the mode to "Add to end of file".
Define the context for number substitution:
[dial_create_chan-custom]exten => s,1,NoOp() ; Only for incoming calls same => n,ExecIf($["${CHANNEL(channeltype)}"=="Local"||"${FROM_DID}x"=="x"]?return) ; No processing required if an internal number is calling same => n,ExecIf(${DIALPLAN_EXISTS(internal,${CONNECTEDLINE(num)},1)}?return) ; No processing required if the number is not in the list same => n,ExecIf($[${DIALPLAN_EXISTS(bluring-extensions,${CHANNEL(endpoint)},1)} ==0]?return) ; Retrieve the cached number same => n,Set(blNumber=${CONNECTEDLINE(num):-4}*${MD5(${CONNECTEDLINE(num)})}) same => n,Set(DB(bluring/${blNumber})=${CONNECTEDLINE(num)}) ; Replace the caller ID same => n,Set(CONNECTEDLINE(num)=${blNumber}) same => n,Set(CONNECTEDLINE(name)=${blNumber}) same => n,return
Describe the context with the numbers for which you need to replace the number:
[bluring-extensions]; Allow number substitution for extension 201exten =>201,1,NoOp(); Allow substitution for all four-digit extensionsexten => _XXXX,1,NoOp()
We will provide the opportunity to call back to a replacement number:
[all_peers](+)exten => _XXXX*.,1,Set(number=${DB(bluring/${EXTEN})}) same => n,ExecIf($["${number}x"=="x"]?hangup) same => n,Goto(all_peers,${number},1)
