Discussion: Polycom reboot hardphone script

there was a slight bug...here is the corrected version...

#!/usr/bin/perl -w

$sipserver   = '192.168.52.1';      # IP of asterisk server

$phone = shift;

checkphone("$phone");
touch( arp2config("$phone") );
$thisextension=get_extension($phone);

reboot_sip_phone( "$phone", "$sipserver", get_extension($phone) );

sub checkphone {                     # Checks for existence of phone, makes sure
         				# it's in arp table
     $activephone = shift;

     # Populate ARP table
     print "Checking ARP table.\n";
     $p = Net::Ping->new("icmp");
     if ( $p->ping( $activephone, 2 ) ) {
         print "$activephone is ";
         print "reachable.\n";
     }
     else { die "Polycom at ", $activephone, " is not reachable!"; }
     sleep(1);
     $p->close();

}

sub arp2config {    # Gets mac address from arp table, converts
                     # to a polycom config filename, makes sure
                     # the config file exists

I had quite a few problems getting this script(s) to work on Asterisk-1.0.7 on Debian 3.1.
On further investigation it turned out that the regex routine in the 'get_extension' sub-routine wasn't picking up the extension number. Also the arp command on Debian is in the '/usr/sbin/ directory.

My revised script is as follows...

#!/usr/bin/perl -w

use Net::Ping;
use Socket;

$polycompath = '/home/PlcmSpIp/';    # Where you keep your polycom files
$arp         = '/usr/sbin/arp';          # Location of arp command
$sipserver   = '192.168.52.1';      # IP of asterisk server

$phone = shift;

checkphone("$phone");
touch( arp2config("$phone") );
$thisextension=get_extension($phone);

reboot_sip_phone( "$phone", "$sipserver", get_extension($phone) );

sub checkphone {                     # Checks for existence of phone,     #makes sure
         				# it's in arp table
     $activephone = shift;

     # Populate ARP table
     print "Checking ARP table.\n";
     $p = Net::Ping->new("icmp");
     if ( $p->ping( $activephone, 2 ) ) {
         print "$activephone is ";
         print "reachable.\n";
     }
     else { die "Polycom at ", $activephone, " is not reachable!"; }
     sleep(1);
     $p->close();

}

sub arp2config {    # Gets mac address from arp table, converts
                     # to a polycom config filename, makes sure
                     # the config file exists
     $arpip = shift;
     open( ARP, "$arp -an|" ) || die "Couldn't open arp table: $!\n";

The version of asterisk I am running (Asterisk CVS-HEAD-04/27/05-08:07:15) has the capability to reboot phones built right in.
