Does any one recognize this binary data storage format

[geskerrett at hotmail.com]

the extension on the files is *.mas  but I a pretty sure it is not
relevant. I beleive it used by the application.

I can posted records as it will take up to much space.
But all three phone numbers are stored in 8 bytes with null bytes (ie.
00) stored in the leading positions (ie. the left hand side)

I do have some more examples;

I have inserted the leading null bytes and seperated with spaces for
clarity.
