translate incoming calls on Cisco router

[samnet]

Hi,

I got one GSM gateway device with many simcards that has a shortcut number ( 0xx12345678)

I want for any calls coming on this number to be translated into internal extension (1000)

can you please help me what should I do on the Router in order to achieve this?

my setup is  ( GSM gateway ==== >  Cisco Router > CUCM)

thanks

You need a translation rule for that purpose, there's plenty of documentation on the topic with config examples on how to use them.
