[asterisk-dev] Why do a DNS search on sip_devicestate

[Gabriel Ortiz Lour]

Hi Asterisk gurus,

  I'm experiencing a problem with my 1.4.19 asterisk and found that has to
do with DNS delays... so looking in the code I have found that the chan_sip
would do like:

static int sip_devicestate(void *data)
.
.
.
... else ...{
        char *port = strchr(host, ':');
        if (port)
            *port = '\0';
        hp = ast_gethostbyname(host, &ahp);
        if (hp)
            res = AST_DEVICE_UNKNOWN;
    }

just to return AST_DEVICE_UNKNOWN, so I was just wondering if someone could
tell me why does it have the trouble to do a DNS lookup and then returns
AST_DEVICE_UNKNOWN

I also saw that 1.6.1.2 does not do this lookup...

Thanks already,
Gabriel Ortiz
