The answer form your carrier has no sense IMHO. You cannot delete arbitrary
headers!

If thye have problem with the size (weird) you should use TCP to connect with
them.


Other answer would be to use a SBC/B2BUA between that carrier and your spce
where VIA and Route headrs would not show as there is only a single hop. 


This is not a spce problem but a carrier problem.


cheers,

Jon
