Motorola. I don't know which firmware it was. I asked for an update to the
owner while I did the dirty hack of removing PRACK and 100rel
from every request and response in the meantime .

Even if you remove 100rel from Supported, they sometimes send PRACK as they see
it in the Allow header.

I know it's strange and buggy, but the only way it worked for me was removing
every 100rel and PRACK reference in the headers.


That was a really old firmware. I hope never will find something similar again.
