I have been running Freeswitch since August 9 without doing any upgrade, as I have been satisfied with how it worked for me. But I thought I should upgrade today, and I checked out the newest svn version. Running Freeswitch now, I only gets 2 of my 3 extensions authenticated with my SIP provider. 37397855 is the only one getting registered, 37048300 and 37048867 is not getting registered. I can see from the log that Freeswitch tries to authenticate 37048300 and 37048867 with 'Digest:"213.160.242.135":37397855:xxxxxx' (x-ing out the password here) Here is part of the log( I wan unable to log in to pastebin, it wouldn't accept my login name and password, even as i was already logged in to freeswitch): 2007-12-03 07:43:20 [DEBUG] sofia_reg.c:774 sofia_reg_handle_sip_r_challenge() Authenticating 'FreeSWITCH' with 'Digest:"213.160.242.135":37397855:xxxxxxxx'. outbound(0x3bb230): detected NAT: 192.168.207.203 != 85.165.221.194 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_i_outbound] status [101][NAT detected] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia.c:245 sofia_event_callback() nua_i_outbound: unknown event 8: 101 NAT detected 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_r_register] status [401][Unauthorized] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia_reg.c:774 sofia_reg_handle_sip_r_challenge() Authenticating 'FreeSWITCH' with 'Digest:"213.160.242.135":37397855:xxxxxxxx'. 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_r_register] status [401][Unauthorized] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia_reg.c:774 sofia_reg_handle_sip_r_challenge() Authenticating 'FreeSWITCH' with 'Digest:"213.160.242.135":37397855:xxxxxxxx'. 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_r_authenticate] status [904][No matching challenge] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia.c:245 sofia_event_callback() nua_r_authenticate: unknown event 47: 904 No matching challenge 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_r_register] status [401][Unauthorized] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia_reg.c:774 sofia_reg_handle_sip_r_challenge() Authenticating 'FreeSWITCH' with 'Digest:"213.160.242.135":37397855:xxxxxxxx'. 2007-12-03 07:43:20 [DEBUG] sofia.c:114 sofia_event_callback() event [nua_r_authenticate] status [904][No matching challenge] session: n/a 2007-12-03 07:43:20 [DEBUG] sofia.c:245 sofia_event_callback() nua_r_authenticate: unknown event 47: 904 No matching challenge And here is part of sofia_conf.xml: <configuration name="sofia.conf" description="sofia Endpoint"> <profiles> <profile name="$${domain}"> <!-- Outbound Registrations --> <gateways> <gateway name="ip24_37048300"> <!--/// account username *required* ///--> <param name="username" value="37048300"/> <!--/// auth realm: *optional* same as gateway name, if blank ///--> <param name="realm" value="213.160.242.135"/> <!--/// account password *required* ///--> <param name="password" value="xxxxxxxx"/> <!--/// extension for inbound calls: *optional* same as username, if blank ///--> <!--<param name="extension" value="cluecon"/>--> <!--/// proxy host: *optional* same as realm, if blank ///--> <param name="proxy" value="213.160.242.135"/> <!--/// expire in seconds: *optional* 3600, if blank ///--> <!--<param name="expire-seconds" value="60"/>--> </gateway> <gateway name="ip24_37048867"> <!--/// account username *required* ///--> <param name="username" value="37048867"/> <!--/// auth realm: *optional* same as gateway name, if blank ///--> <param name="realm" value="213.160.242.135"/> <!--/// account password *required* ///--> <param name="password" value="xxxxxxxx"/> <!--/// extension for inbound calls: *optional* same as username, if blank ///--> <!--<param name="extension" value="cluecon"/>--> <!--/// proxy host: *optional* same as realm, if blank ///--> <param name="proxy" value="213.160.242.135"/> <!--/// expire in seconds: *optional* 3600, if blank ///--> <!--<param name="expire-seconds" value="60"/>--> </gateway> <gateway name="ip24_37397855"> <!--/// account username *required* ///--> <param name="username" value="37397855"/> <!--/// auth realm: *optional* same as gateway name, if blank ///--> <param name="realm" value="213.160.242.135"/> <!--/// account password *required* ///--> <param name="password" value="xxxxxxxx"/> <!--/// extension for inbound calls: *optional* same as username, if blank ///--> <!--<param name="extension" value="cluecon"/>--> <!--/// proxy host: *optional* same as realm, if blank ///--> <param name="proxy" value="213.160.242.135"/> <!--/// expire in seconds: *optional* 3600, if blank ///--> <!--<param name="expire-seconds" value="60"/>--> </gateway> </gateways> If I delete the two last gateways, I can get 37048300 registered. What have changed here since August? Ivan
