Hello! I've been trying to get my SIP clients to register and authenticate with freeswitch without passwords. I've been following a few wiki pages, primarily: http://wiki.freeswitch.org/wiki/Acl and http://gnuradio.org/redmine/wiki/gnuradio/OpenBTSSettingUpFreeSWITCH Most of the configs are stock, except my directory which has one new user in the "default" folder: <include> <user id="IMSI641104378340883" cidr="192.168.1.0/24,127.0.0.1/32" number-alias="1301"> <params> <param name="vm-password" value="1000"/> <param name="accept-blind-reg" value="true"/> <param name="accept-blind-auth" value="true"/> </params> ... This config is working in one one way, I do not need to register to make a call. The phone is currently able to call into FS. However, any attempts to register ()REGISTER messages) are met with a 401 authorization required response (as shown by wireshark). This means FS is unable to route calls to my handsets. My understanding was that the line, <param name="accept-blind-auth" value="true"/> when coupled with the cidr value, would remove that need. It's clearly not working. I've tried a variety of other config options (e.g., <param name="apply-register-acl" value="<acl_list|cidr>"/>), and found no joy. ACLs are complicated business, and I could take a few more stabs in the dark (using localnet.auto?). However, I thought I'd ask this list. What else do I need to do to let my users connect without a password? Thanks!
