The bigger issue you are going to have is the larger packets. So many devices out there can't seem to fragment packets correctly.
There are many other reasons why SIP messages are getting bigger and bigger, of which STIR/SHAKEN is not the first, second or fifth: other standards, WebRTC interop, more/wideband codecs in SDP bodies, SRTP(-SDES/DTLS), support for other features and standards, etc. So, this problem needs to be dealt with one way or another and is pervasive irrespectively of STIR/SHAKEN. The solution, of course, is to use SIP over TCP. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/
