  Sir,


  I am not really sure what you are trying to accomplish.
  How do you want to avoid fragmentation by setting a minimum packet size ?
  You can't really avoid fragmentation.
  If a SIP packet is larger than 1500, than it is larger.
  If you want to avoid fragmentation, you will need to suppress unnecessary SIP headers, or eventually you may try to enable short headers but that's not quite supported by all vendors.
  Supressing unnecessary headers is quite easy with a B2BUA like FreeSWITCH, as most headers should already not be forwarded.
  SIP INVITEs over 1500 is generally a problem when you proxy, adding Route information, etc...

    is it useful to set minimum UDP  pakcet to the
    MTU rate like 1500 and avoid any fragmentation ?
