I figured out that there is some sort of incompatibility with snom and asterisk's sip. For the first time the authentication looks like: NOTICE[5126]: File chan_sip.c, Line 4424 (handle_request): Failed to authenticate user <sip:800@157.181.25.113>;tag=yiubra2azl for SUBSCRIBE NOTICE[5126]: File chan_sip.c, Line 4486 (handle_request): Registration from '"Levi" <sip:800@157.181.25.113>' failed for '62.112.220.107' NOTICE[5126]: File chan_sip.c, Line 4424 (handle_request): Failed to authenticate user <sip:800@157.181.25.113>;tag=yiubra2azl for SUBSCRIBE NOTICE[5126]: File chan_sip.c, Line 4486 (handle_request): Registration from '"Levi" <sip:800@157.181.25.113>' failed for '62.112.220.107' -- Registered SIP '800' at 62.112.220.107 port 5060 expires 60 And after this expires I just keep getting the following messages 10-50 per registration period: NOTICE[5126]: File chan_sip.c, Line 4486 (handle_request): Registration from '"Levi" <sip:800@157.181.25.113>' failed for '62.112.220.107' NOTICE[5126]: File chan_sip.c, Line 4486 (handle_request): Registration from '"Levi" <sip:800@157.181.25.113>' failed for '62.112.220.107' NOTICE[5126]: File chan_sip.c, Line 4486 (handle_request): Registration from '"Levi" <sip:800@157.181.25.113>' failed for '62.112.220.107' What can be the problem? Cos usually after a few minutes it registers itself again. And so on. But in the time the phone is unregistered it can't reveice any calls. -------------- next part -------------- An HTML attachment was scrubbed...
