, but when the packets are more than 1100, kamailio send packets
less 1000 and connection to softphone fail<br>

You are going to have to provide a lot more detail than that if you
want help. For example packet captures of how the packet looks like
before and after being redirected.<div><div class="h5"><br>

are you sure it is happening when the packet is
