I'm having trouble connecting a asterisk server to a SIP Express router. Inbound calls to my asterisk server works just fine, but when i try to make outbound calls I get the following error message: Nov 27 22:40:48 NOTICE[4687]: chan_sip2.c:7967 handle_response: Failed to WWW-authenticate on INVITE to '"username" <sip:username@mysipprovider>;tag=as5399a078' I'm currently running Asterisk CVS-HEAD-11/27/04-15:07:27 and chan_sip2.c downloaded today. I had the problem using chan_sip as well, but the error message was slightly different. Below is a packet dump from the SIP session. My current sip.conf configuration is: --- register => mynumber:mypass@mysipprovider/mynumber [authentication] auth=mynumber:mypass@mysipprovider [mynumber] type=peer username=mynumber fromuser=mynumber secret=mypass fromdomain=mysipprovider host=mysipprovider insecure=very --- Any help would be deeply appreciated!
