Really annoying as I got this all working,then two days later the PC threw a hissy fit and recovered itsself, since when I cannot make calls.
I get a dialling tone but when I try to connect nothing happens.
The start of the log file gives "Discovered Port Restricted Cone NAT Firewall" but then seems to login OK but towards the end after I have tried to make a call I see "SIP/2.0 407 Proxy Authentication Required" and also "Warning: 392 22.214.171.124:5060 "Noisy feedback tells:"
It is really annoying because it was wotking and now it has stopped and left me flummoxed trying to remember what else I might have changed to get things going!!
