Sending SIP notify to polycom in order to resync/reboot it
by Yehavi Bourvine 09 Mar '10

09 Mar '10

Is there a simple way/command inside FreeSwitch to send a NOTIFY message to a Polycom phone which tells it to reboot? I know it is possible but I do not find any documentation about it... Thanks, __Yehavi:

vars from sip_registrations table
by Madovsky 09 Mar '10

09 Mar '10

in sip_registration table there are call_id sip_user sip_host presence_hosts contact status rpid expires user_agent server_user server_host profile_name hostname network_ip network_port sip_username sip_realm mwi_user mwi_host orig_server_host orig_hostname fields, so how can I get these vars from the callee before the bridge ? I need to replace the host of the callee in case of if he's registered on another FS node. thanks Franck

I noticed that if a registration doesn't close properly and try to reconnect I can see in the table sip_registrations the old reg and new one. is it normal ? if yes, How FS can guess the right registration in case of multiple FS with shared DB ? Thanks Franck

recvEventTimed - SERVER_DISCONNECTED
by Nagalenoj H. 09 Mar '10

09 Mar '10

Dear friends, I've faced an issue in event socket. I would want to know why it behaves such a way. My program is working with the hep of events. So, based on the received event, the process will continue it's work. When I need DTMF, I use recvEventTimed and in the other cases, I use recvEvent. So, In the mid if caller hangsup, I expect for the SERVER_DISCONNECTED event. When the caller hangsup when I'm waiting in recvEvent, I'm getting SERVER_DISCONNECTED. But, when I'm waiting in recvEventTimed, I'mnot receiving SERVER_DISCONNECTED, instead receiving an undefined value. To handle this, I've checked esl connection inside the timeout part and put a recvEvent, then I receive SERVER_DISCONNECTED. My question is, why am I not receiving SERVER_DISCONNECTED when I recv event using recvEventTimed?! This is a sample program I execute, require ESL; use IO::Socket::INET; my $ip = "127.0.0.1"; my $sock = new IO::Socket::INET ( LocalHost => $ip, LocalPort => '9242', Proto => 'tcp', Listen => 1, Reuse => 1 ); die "Could not create socket: $!\n" unless $sock; for(;;) { my $new_sock = $sock->accept(); my $pid = fork(); if ($pid) { close($new_sock); next; } my $host = $new_sock->sockhost(); my $fd = fileno($new_sock); my $con = new ESL::ESLconnection($fd); my $info = $con->getInfo(); my $uuid = $info->getHeader("unique-id"); printf "Connected call %s, from %s\n", $uuid, $info->getHeader("caller-caller-id-number"); my $e = $con->filter("unique-id", $uuid); if ($e) { print $e->serialize(); } else { printf("WTF?\n"); } $con->events("plain", "SERVER_DISCONNECTED DTMF"); $con->execute("answer"); while($con->connected()) { $e = $con->recvEvent(); ############# CASE 1 ## # $e = $con->recvEventTimed(10000); ############# CASE 2 ## unless ($e) { unless ($con->connected()) { ############################### $e = $con->recvEvent(); ## print $e->serialize(); ## Added code to get SERVER_DISCONNECTED. print "SERVER_DISCONNECTED"; ## } ############################### print "DTMF timeout\n"; } if ($e) { my $name = $e->getHeader("event-name"); print "EVENT [$name]\n"; if ($name eq "DTMF") { my $digit = $e->getHeader("dtmf-digit"); my $duration = $e->getHeader("dtmf-duration"); print "DTMF digit $digit ($duration)\n"; } } } print "BYE\n"; close($new_sock); } -- Regards, Nagalenoj H.

Which Lua script am I?
by Mike van Lammeren 09 Mar '10

09 Mar '10

Hello! I am working on a high-availability system and need a Lua script that can run in the background and loop forever, periodically waking up to accomplish some tasks. I would like to be able to handle at least 10 concurrent tasks. My first idea was to have a simple background script that would call another script, let's call it the 'task' script, every 5 seconds or so. This would spread the work around, and if any task script quit with an error, the background script would remain running, and would continue to launch new task scripts. However, I can see no way for the background script to launch other Lua scripts. Am I missing something? I need something like session:execute(), but unfortunately this background script has no session, and I'm not sure if session:execute() can even make a call like the "luarun" console command. So, my next ideas was to have 10 copies of the background script. Each script would loop forever. Upon launch, each script would perform a single task, then sleep for 60 seconds. This allows handling of 10 concurrent tasks. However, there are some problems with running 10 copies of the same script, which I believe can be solved if each script could be given a unique identifier. One problem is that I would like the scripts to actually sleep for a variable amount of time, say between 55 and 65 seconds, so that the workload would spread around. Another, similar problem, is that each script needs to 'claim' a number of database records from a table that is queuing up work for the scripts. Once again, if each script had a unique identifier, then I could use an update query to effectively 'set and test' a record that would be tied to that script instance. I could use a random number to identify each script, but since math.random is seeded with a timestamp that only resolves to seconds, then all 10 scripts will be given the same sequence of random numbers, and all 10 will run in lock-step with each other. So, random numbers are out. (If I had a unique ID to seed the random number generator, then I could just use that unique ID and wouldn't need random numbers.) Is there a way of uniquely identifying 10 Lua scripts that FreeSWITCH launches at startup? Or is there a better way of handling this situation altogether? I'm open to any suggestions that people would care to make! (I would entertain the idea of a single script that would start with FreeSWITCH, then launch 10 other scripts, giving each a unique identifier, but that brings me back to the original problem of not knowing how to launch other Lua scripts under FreeSWITCH.)

hunt group - play music when trying external numbers
by William Traenkle 09 Mar '10

09 Mar '10

I did not see this message go through yet so I removed the code I originally had pasted and am resending it. FS Community, I am new to freeSWITCH and this mailing list and I appreciate your support in advance. My Goal: To create a hunt group x7000 that sequentially dials an internal extension, i.e. x1000, and then a cell phone number, i.e. 6194548924, while playing music the entire time when each number is being tried. The Issue: This was working great a few months back, but now music plays when only when x1000 is tried but NOT when the cell phone is tried. Ideas? Please advise. Thanks. -Will
