Record-Route headers are an integral part of SIP, and every device 
compliant to SIP really MUST support them.

There is no way to remove them from the SPCE without completely and 
horribly breaking the call flows.

If they insist on removing them, you better change your trunking 
provider as they obviously don't know what they are doing.
