Куда кривее?)

<?php
$astip="194.44.xxx.xxx";
$astmanager="admin";
$astpassword="admin";
  $socket = fsockopen($astip,"5038", $errno, $errstr);
  fputs($socket, "Action: login\r\n");
  fputs($socket, "UserName: $astmanager\r\n");
  fputs($socket, "Secret: $astpassword\r\n\r\n");
  fputs($socket, "Action: QueueAdd\r\n");
  fputs($socket, "Queue: 977\r\n");
  fputs($socket, "Interface: SIP/777\r\n");
  fputs($socket, "Action: Logoff\r\n\r\n");
?>

Так работает

  $socket = fsockopen($astip,"5038", $errno, $errstr);
  fputs($socket, "Action: login\r\n");
  fputs($socket, "UserName: $astmanager\r\n");
  fputs($socket, "Secret: $astpassword\r\n\r\n");
  sleep(1);
  fputs($socket, "Action: QueueAdd\r\n");
  fputs($socket, "Queue: 988\r\n");
  fputs($socket, "Interface: SIP/731\r\n");
  sleep(1);
  fputs($socket, "Action: Logoff\r\n\r\n");
