The external gateway receives numbers after translation by the Numbering Plan Descriptor and convert them into URLs for the INVITE message:
If the number is of national type (TON = Nat), the country code managed in system parameter (see module SIP / Configuration procedure ╖ Country Code) is added in front of the number
If the number is of international type (TON = Int), the country code is not added
Example:
In, the following SETUP message received by the external gateway, the country code is added to the called number but not to the calling number:
SETUP
Called # : 147858000 TON = Nat
Calling # : 33155669001 TON = Int
will generate the following INVITE request towards the operator
INVITE sip:+33147858000@RemoteDomain SIP/2.0
To : <sip:+33147858000@RemoteDomain>
From : <sip:+33155669001@LocalDomain>
Rout : <sip:operator@there.com>
