Bad luck then... :( SIP ALG is the worst enemy for SIP.
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.
Best regards
