Dear all, does anyone here use *bubua with Freeradius? I notice that when *bubua want to get the Session-Timeout values, *bubua will send the following message to radius servers(Here I use Freeradius): rad_recv: Access-Request packet from host 59.64.180.238:33150, id=57, length=246 Cisco-Call-Type = "VoIP" Calling-Station-Id = "005001" Called-Station-Id = "005000" Cisco-NAS-Port = "SIP/59.64.141.26-b7b13d20" Cisco-AVPair = "call-codec=ulaw;useragent=X-Lite release 1105x;" h323-call-origin = "originate" User-Name = "005001" NAS-Identifier = "Asterisk" Framed-IP-Address = 59.64.141.26 NAS-IP-Address = 59.64.180.238 NAS-Port = 5060 h323-conf-id = 4C6B297B-8DC5-41A5-A6B8-C285B04BEF00@59.64.203.93 Here is the problem: the message didn't contain any password information (in fact *bubua won't send the password), and then Freeradius will reject the request because of lack of password. The Freeradius debug information is: auth: No User-Password or CHAP-Password attribute in the request auth: Failed to validate the user. My question is how to make the radius server accept the request which do not contain the password and reply the Session-Timeout to the *b2bua? Thanks!
