This is a (lack of) SAR support issue. The 900 bytes sounds familar -

No - the size of the segment is selected by the client and I have not
seen a device where this is configurable.
 
SAR is a both way service.

It does. My T68i supplies a WSP encoded Profile: header that the
gateway decodes correctly and passes onto the origin server as;
