You really can’t really blame the issues with particular clients on the SIP protocol/standard. Anyone working with SIP should keep this in mind. That was two years ago and it hasn’t been fixed. They initially denied the home routers had any SIP ALG – their business products do, however it turns out the home routers have the SIG ALG enabled in an invalid state and the engineers merely disabled the user interface to control it. I reported this bug to netgear, and they eventually were able to confirm the bug. However, this can be fixed by using domain names instead of IP addresses.
#VOXOX SIP SETTING CODE#
Since I was debugging the source code (initially thinking it was a client issue), I modified the client to ignore the mangled IPs, which “solved” the problem. When the packets are acked, netgear routers substitute which is wrong so the client drops the ACKs. The problem is that the 4 byte substitution was applied on raw packets without regard to the SIP fields – whoever programmed this was an idiot.Īnyways, many sip clients use to identify themselves. Once I realized what was happening it was easy to recognize, the router was corrupting all values which appeared to match an internal/external IP address and mangled the values. (It took me hours to discover this by looking at wireshark traces). Many home netgear routers have a SIP ALG bug which causes corruption and breaks SIP calls even when the port forwarding is correct. To anyone who’s having trouble with SIP port forwarding on netgear routers: This is terribly difficult to accomplish behind NAT routers – particularly those which I don’t own/control. However it is one of the worst thought out protocols I’ve ever had to deal with on account of assuming that both ends can open up arbitrary public facing ports.
