asterisk users - Sep 2003 - Asterisk SIP DNS srv records

I've tried to find documentation on if Asterisk supports DNS SRV records for
sip servers.

Reading the source of channel_sip.c it seems not:

    hp = gethostbyname(hostname);
    if (!hp) {
	ast_log(LOG_WARNING, "Host '%s' not found at line %d\n",
hostname, lineno);
         return -1;
     }

This is in the register part.

Am I correct in this or have I missed something?
