  workarounds could be:
 - run sip server also on a different port than 5060 (say 5070) - 
 kamailio is just fine doing it. Point the users behind such ALGs to this 
 port. Still alg can detect it, but most of them do the detection by port 
 5060
 - use TCP if the phone supports it - most of algs do not touch TCP 
 connections, but ...
 - use TLS if the phone supports it - safest - the alg cannot touch it 
yes, we are planning to use TLS and I hope we won't have that kind of problems then

...
  - recommended - send back the router and ask for money
return 
well, I could do that but the problem is not just with this router. I saw a list of this
kind of routers (small home routers) that are not recommended to use with SIP, and I think
that TLS is only universal solution.
