I know there are plenty of posts on this problem and I have tried them all and still having problems with incoming calls. They are failing with the 407 message on the SIP INVITE. I have two SIP phones set up as extensions to Asterisk and can ring internally fine. I ring the Asterisk demo no worries. I can also ring outbound any number fine, so its only on inbound I am having problems. I have a very simple sip.conf and extensions.conf.
secret=(same password as above)
I have been on to blueface about this and this is the config suggested with a few additions myself to try and get it working. Initially my blueface account didn’t accept a username and password but were added in to try to fix the problem.
I’m using Asterisk 1.2.18 on FC6.
There no Nat to consider
Of course there is extra configurations for outbound but this is fine and the names used are different to ensue no conflict. I really don’t know what else to try, so any suggestions appreciated.
