Lookup / Find

I have a table with unique mobile telephone numbers and a table which has a list of all calls made to a contact centre over a period of time.   I am looking to find out how many calls were made by each number in the unique table of telephone numbers, however, I cannot match these up with the other table as the numbers in this particular table sometimes have a 9 placed in front of them and on other occassions have the leading 0 removed from the mobile number.   

Is there anyway to match these up and do a count using DAX?

Thanks

I wish there was but there is no pattern to the way in which the numbers are altered in the system and therefore I can't do something simple like removing the first character or even changing it as far as I know.

@Caseyc1983 ,

Cleaning the data using Power Query isn't an option ?
