Sorry to drudge up an old issue, but I haven't found a solution for this yet. My Cisco phones (7940/60/70) with the latest SIP firmware wont authenticate properly with *. They register just fine, but when I try to actually make a call, I get chan_sip.c:10299 handle_request_invite: Failed to authenticate user "5001" <sip:[EMAIL PROTECTED]>;tag=000a8a5c671600781097ccc1-7ddc1905
Based on output from SIP debug, it appears that either the phone or asterisk is trying to do SIP digest authentication once the phone is registered, and it's failing. Is there any way to work around this (either on the phone or asterisk). Right now the only workaround is to set secret=<blank>, and that's not a viable solution. Cheers, Gary
