I am new to Asterisk.
I have lab setup with Elastix 1.6-12, two Aastra sip extensions (dialog 422) and two softphones (X-lite and SJphone) . No trunks connected.
I can make calls from softphones to each other and the Aastra extensions.
Can not make call from extensions to softphones nor other extension. Get busy tone.
Ran wireshark: There 's a message from the elastix server to the phone saying “407 Proxy authentication required” .
It seems as if the phones are not registered properly. They can be called but can’t make calls.
Anyone an idea…?
