Dear all,
I have a question regarding SIP MESSAGE request specified in RFC
3428. It specifies that ...
"""
The size of MESSAGE requests outside of a media session MUST NOT
exceed 1300 bytes, unless the UAC has positive knowledge that the
message will not traverse a congestion-unsafe link at any hop, or
that the message size is at least 200 bytes less than the lowest MTU
value found en route to the UAS. Larger payloads may be sent as
part of a media session, or using some type of content-indirection.
"""
How can I guarantee that the message will not grow above this 1300
bytes limit when being routed through a chain of proxies (which add
their via headers -> increases the message size...)
Any help would be appreciated.
Thank you,
Holger
