Dear
For outgoing call , you will use DOD .Firstly you have to check with your ITSP that they will ok to allow your DOD.
what you need that (you will have ext 2001 , you will need to show it for outgoing call 78999992001). It is so eazy.
you have to create CSS outgoing calling id for exampl (HQ-callout)
1- Go to each phone and go to DN >external phone number mask)
and type for example 78999992xxx (where 2 is the start digit and xxx represents the last three digits).
2-go to call routing > Transfomation>Transformation pattern>calling party transformation pattern
3-enter yor roue pattern for the outgoing calls which you have created before (9.!) ,enter the css
(HQ-callout) then under calling party information
check ( use calling party's external phone number mask)
4- on the gateway
a. Go to Device -> Gateway, look for the MGCP device and under
“Call Routing Information - Outbound Calls” look for “Calling Party Transformation CSS”,
configure there the Calling Search Space we created =Transformation_CSS .Uncheck the “Use Device Pool Calling Party Transformation CSS”.
b. The other workaround is to Go to the configuration page of the MGCP
gateway in CallManager, under “Call Routing Information - Outbound Calls”:
c. Look for the parameter: “Number of digits to strip” and set it to 1.
This way the CallManager will remove the 9 for all any outbound call, however for normal
calls IP phone to PSTN it will also remove the first digit so you can configure a 1 in front of
the “External Phone Number Mask” in the line settings.
d. Set the “Caller ID DN” as XXXXXXX (x = same amount of digits of your External PhoneNumber Mask),
Other solution
Kindly check the below image , you can edit the route pattern .
