      <p>Hello,</p>
      <p>the long Via branch is because of using topoh module. Do you
        need that?</p>
      <p>The alternatives would be:</p>
      <p> - disable topoh module</p>
      <p> - or configure the kernel to do udp defragmentation (should be
        default in modern linux)</p>
      <p> - or switch to tcp/tls<br>
      </p>
      <p> - or try to use the new topos module in 4.4 -- not that it is
        not well tested and you should not go with it in production
        directly. Any issue encountered with topos should be reported on
        kamailio project on github and I will take care fixing them.</p>

        <pre wrap="">Good morning list,

I need to ask you a question about a problem we are fighting on our VoIP
platform based on Kamailio 4.3.5.
Our platform is made by more nodes over Europe countries, and we are
encountering a problem with the size of the SIP package which, exceeds
the physiological limit of about 1350 bytes.
The real problem is caused from Via: Header (inside the SIP packet)
which is added to each element of the system for transit on the call.
>From what we have analyzed, the problem is not so much due to the number
of entered Via: records but, by the fact that they contain a branch
parameter extremely long.

Here the call flow example from CARRIER A —> Kamailio1 —> Kamailio2 —>

Is there anyone here with the idea how to solve this problem ?
