SIP was never really designed to work with network address translation.Īgain, try getting things working on the same subnet, with no NAT or routing involved, before moving on to more difficult tasks. SIP (the VoIP protocol behind Asterisk) HATES NAT I would strongly advise troubleshooting on dedicated physical hardware. I don't know if they have specific guidance on this, but my experience is even in high-end VMWare environments you can get into all sorts of odd trouble with virtualized VoIP servers. Do you have any suggestions what we could do? Would may be wireshark be of any help? Any information, help or suggestion is much appreciated (also if you know good tutorials how to set up asterisk with freepbx)!Īsterisk does very poorly in virtual machines. Now, I know it's a very vague description of our problem and the error could be anywhere - but we don't even know where to start to look for the error. We configured the IP of the asterisk server as static. On the modem we forwarded all incoming requests on port 5060 to the local router and this router forwards all requests to the local IP of our asterisk-server. In X-Lite we specified the IP of the modem of the local network in which the asterisk server resides. But now, we would like to be able to access the server also from the internet - this is what we're strugglin with. We tried the configuration by registering some SIP-Phones via X-Lite in the local network, and it worked. Thus we have installed asteriskNow in a virtual environment (with virtualBox) on ubuntu 12.10. We currently have a school-project going in which we need to set up an PBX with Asterisk.
