I mean the output when you type ./configure in the asterisk source code directory before you do "make menuconfig"
"line 0" means it is reading the peer configuration from the database and the messages mean it is trying to define the peer with the values. It is a warning, but it is unusual since the values are empty. I personally have not seen these type of messages but not sure if it is because the buddies file is not used directly, but from a VIEW.
For example, it was desirable to change canreinvite to directmedia and a couple other things.
Code:
CREATE VIEW `cc_sip_buddies_custom` AS select `cc_sip_buddies`.`id` AS `id`,`cc_sip_buddies`.`id_cc_card` AS `id_cc_card`,`cc_sip_buddies`.`name` AS `name`,`cc_sip_buddies`.`accountcode` AS `accountcode`,`cc_sip_buddies`.`regexten` AS `regexten`,`cc_sip_buddies`.`amaflags` AS `amaflags`,`cc_sip_buddies`.`callgroup` AS `callgroup`,`cc_sip_buddies`.`callerid` AS `callerid`,`cc_sip_buddies`.`cid_number` AS `cid_number`,`cc_sip_buddies`.`canreinvite` AS `directmedia`,`cc_sip_buddies`.`context` AS `context`,`cc_sip_buddies`.`defaultip` AS `DEFAULTip`,`cc_sip_buddies`.`dtmfmode` AS `dtmfmode`,`cc_sip_buddies`.`fromuser` AS `fromuser`,`cc_sip_buddies`.`fromdomain` AS `fromdomain`,`cc_sip_buddies`.`host` AS `host`,`cc_sip_buddies`.`insecure` AS `insecure`,`cc_sip_buddies`.`language` AS `language`,`cc_sip_buddies`.`mailbox` AS `mailbox`,`cc_sip_buddies`.`md5secret` AS `md5secret`,`cc_sip_buddies`.`nat` AS `nat`,`cc_sip_buddies`.`deny` AS `deny`,`cc_sip_buddies`.`permit` AS `permit`,`cc_sip_buddies`.`mask` AS `mask`,`cc_sip_buddies`.`pickupgroup` AS `pickupgroup`,`cc_sip_buddies`.`port` AS `port`,`cc_sip_buddies`.`qualify` AS `qualify`,`cc_sip_buddies`.`restrictcid` AS `restrictcid`,`cc_sip_buddies`.`rtptimeout` AS `rtptimeout`,`cc_sip_buddies`.`rtpholdtimeout` AS `rtpholdtimeout`,`cc_sip_buddies`.`secret` AS `secret`,`cc_sip_buddies`.`type` AS `type`,`cc_sip_buddies`.`name` AS `defaultuser`,`cc_sip_buddies`.`disallow` AS `disallow`,`cc_sip_buddies`.`allow` AS `allow`,`cc_sip_buddies`.`musicclass` AS `musicclass`,`cc_sip_buddies`.`mohsuggest` AS `mohsuggest`,`cc_sip_buddies`.`regseconds` AS `regseconds`,`cc_sip_buddies`.`ipaddr` AS `ipaddr`,`cc_sip_buddies`.`cancallforward` AS `cancallforward`,`cc_sip_buddies`.`fullcontact` AS `fullcontact`,`cc_sip_buddies`.`setvar` AS `setvar`,`cc_sip_buddies`.`lastms` AS `lastms` from `cc_sip_buddies`;
You can try this to see if it works for you.
