You could make your Quintum send anything in front of the digits.
The only limitation is that the prefix that you setup will be sent on every call that comes out of the gateway, always.
IP Trunk Group
—————
Incoming IP call delete digits = 0
Incoming IP call prefix =
Outgoing IP call delete digits = 0
Outgoing IP call prefix = 00
Prefix Trunk ID = no(0)
Default Trunk = No
External Routing Request = no(0)
Display Information ID = Tenor-Gateway
Inset the “00” on the filed called outgoing I.P. call prefix.
When someone ‘s dial 00 plus a call, the quintum will delete the leading 00, process the call to the destination, and insert a couple of ceros on front of the call.
001 713 207 5000 call to USA
1 713 207 5000 leading 00 deleted
call get routed
001 713 207 5000 is sent to the remote terminal.
Best luck!!!
