Hello,  
I have a script that checks for the clidid existence.  
It worked fine with older version of asterisk (1.4.x)  
Now after i switched to the latest(1.6.2.0) i get errors but the script works fine.  
ERROR[13171]: utils.c:1126 ast\_carefulwrite: write() returned error: Broken pipe

any ideas?

#!/usr/bin/php -q

 \<?php ob\_implicit\_flush(true); set\_time\_limit(6); $in = fopen("php://stdin","r"); $stdlog = fopen("/var/log/asterisk/my\_agi.log", "w"); // toggle debugging output (more verbose) $debug = false; // Do function definitions before we start the main loop function read() { global $in, $debug, $stdlog; $input = str\_replace("\n", "", fgets($in, 4096)); if ($debug) fputs($stdlog, "read: $input\n"); return $input; } function errlog($line) { global $err; echo "VERBOSE \"$line\"\n"; } function write($line) { global $debug, $stdlog; if ($debug) fputs($stdlog, "write: $line\n"); echo $line."\n"; } // parse agi headers into array while ($env=read()) { $s = split(": ",$env); $agi[str\_replace("agi\_","",$s[0])] = trim($s[1]); if (($env == "") || ($env == "\n")) { break; } } // main program // main program $cli = $agi[callerid]; $exten= $agi[extension]; //$pattern = "\*\\<[0-9]+\\>\*"; $pattern = "\*[0-9]+\*"; preg\_match($pattern,$cli,$matches); $out = trim($matches[0], "\<\>"); errlog("Call from -$out-"); errlog("Call from -$cli-"); errlog("Call from -$matches[0]-"); If (!$out) { write ("SET CONTEXT from-sbc"); write ("EXEC GoTO from-sbc|s|1"); } Else { write ("SET CONTEXT planusers"); write ("EXEC GoTO $out,1"); } // clean up file handlers etc. fclose($in); fclose($stdlog); exit; ?\> 

when asterisk executes it it give errors:
