I don't think the leading underscore is part of the source. . and it's 
defined in the channels dir:

/usr/src/asterisk/channels# grep SIP_CODEC *
chan_sip.c: 
codec=pbx_builtin_getvar_helper(p->owner,"SIP_CODEC");
chan_sip.c:                             ast_log(LOG_NOTICE, "Changing 
codec to '%s' for this call because of ${SIP_CODEC) variable\n",codec);
chan_sip.c:                                     ast_log(LOG_NOTICE, 
"Ignoring ${SIP_CODEC} variable because it is not shared by both ends.\n");
chan_sip.c:                     } else ast_log(LOG_NOTICE, "Ignoring 
${SIP_CODEC} variable because of unrecognized/not configured codec 
(check allow/disallow in sip.conf): %s\n",codec);
