Thanks for your quick response.
No, you can't remove those headers. They serve an essential purpose and the
endpoints won't consider the requests or responses
valid without them.
It should be theoretically possible to remove some of the via and
record-route headers, assuming the contact is also re-written. The end
point's (phones) themselves do not need to be aware of anything downstream
of the SIP server they're registered too.
Thanks for the link!
