pjsua dns wierdness with pennytel.

[shayne.oneill@xxxxxxxxx (Shayne O'Neill)]

Hey guys,

I'm getting some erratic DNS weirdness from Pennytel, and I'm  
wondering if its something I should be handling in my code.

Heres the code I'm using..

	if (([defaults stringForKey:@"dnsserv"] != nil) && (![[defaults  
stringForKey:@"dnsserv"] isEqualToString:@""])) {
		NSLog(@"Setting DNS server %@",[defaults stringForKey:@"dnsserv"]);
		cfg.nameserver_count = 1;
		cfg.nameserver[0] = pj_str([[defaults stringForKey:@"dnsserv"]  
UTF8String]); }
	else {
		cfg.nameserver_count = 0;
	}

The bracket stuff is just ObjC semantics to extract the server from  
the settings..

Heres the log outputs.
