Nortel BCM <-> Asterisk
I've recently been working on linking our Nortel BCM 400 and Nortel BCM 50s to an Asterisk server to allow SIP DIDs and SIP trunks.
When the BCM sends calls to Asterisk it specifies the context in the call. This code will remove it.
Contents of /var/lib/asterisk/agi-bin/bcm-fix.pl
#!/usr/bin/perl
#
# Strip extra data out of BCM calls to allow them to work with Asterisk.
#
#
use Asterisk::AGI;
my $AGI = new Asterisk::AGI;
$SIG{HUP} = "IGNORE";
my $destination = $ARGV[0];
$destination =~ s/;phone-context.*//g;
$AGI->exec('Dial','Local/' . $destination . '@from-internal');
exit(0);
Custom context for inbound BCM calls:
[from-internal-bcm]
exten => _.phone-context.,1,AGI(bcm-fix.pl,${EXTEN})
include => from-internal

This is exactly what I need. My BCM50 will drop the phone-context when I remove the CDP from URI settings, but the BCM400 will leave it there.
ReplyDeleteI have problems though. I created the bcm-fix.pl and put the custom context in my extensions_custom.conf changed the name to match my system(from-trunk), but it doesn't look like it's running the script. If I just run the script I get a "Can't locate Asterisk/AGI.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at ./bcm-fix.pl line 7."
When I do a "locate AGI.pm" nothing comes up. I am using FreePBX 2.10 with asterisk 1.8. Any ideas? Thanks
Try installing the Asterisk::AGI module from CPAN. I'm typing this command from memory...
Deleteperl -MCPAN -e shell
Say no to autoconfiguration and then type
install Asterisk::AGI
That should get you the missing perl module

ReplyDeleteI was missing a few things. Asterisk-perl 1.03, ExtUtils::MakeMaker and perl-devel. So now I just have to figure out more about custom extensions. I noticed in your script you had "from-internal" but in mine it all looks like it should be "from-trunk". I tried changing a few different things but still couldn't get it to work.
ReplyDeleteHere is what I get in my "full" log. Should I be changing your script to match "from-trunk"?

I have it as from-internal as that's where calls from my BCM400 end up. Do you have a SIP trunk setup for your BCM? Here's my trunk settings:
ReplyDeletehost=10.10.10.1
type=peer
insecure=very
qualify=yes
context=from-internal-bcm
disallow=all
allow=ulaw&alaw
canreinvite=no
Every call coming in from the BCM hits the script and then gets pushed into the from-internal so it's just like a typical SIP call coming in from an extension.
I did finally get it working. It was because of the context settings. Thanks for your help and the script.
ReplyDeleteOur BCM finally died. It made for an interesting week running with a 1/2 broken phone system. We're really happy with our new FreePBX based system.
