[asterisk-users] cisco phones getting SIP 401 unauthorized

[Matt Gibson]

Did the server reboot or lose communication? This happens with our 7970's
sometimes if there's been a hiccup, usually dialing voicemail registers them
back up - occasionally we've had to do the soft reboot from the screen. 

401 unauth - looks like it may be md5secret issue, or nat traversal over a
firewall - are the phones inside the lan or on the net?

Thanks,
Matt G
