Is it really necessary to setup a dynamic dns and have asterisk resolve it when it is only connecting out to sip services?
Even when it still had the old IP in there i was able to make calls ok it seemed, incoming calls however had no audio.
I don't really want to get a static IP as this is all I need it for, and don't want to have to rely on dynamic ip updates since thats just creating unneeded traffic, I thought that sip servers got the IP from the source address rather then the payload, is that the case or not? I can understand the need to have the real IP available to asterisk if I was to be connecting sip clients in from the internet, but I am not wanting to do that at this stage since the lag is way too bad when doing that.
