Logical OR in conditions
by Matthew Ralston 09 Jun '11

09 Jun '11

Hi, What is the correct condition->break value to use in order to create a logical OR with conditions? I have two extensions which I'd like to merge into one. I'd like the actions to be run if either of the conditions matches: <extension name="call_forward_enable"> <condition field="destination_number" expression="^\*21\*([0-9]+)#$"> <action application="javascript" data="callForwardEnable.js"/> <action application="hangup"/> </condition> </extension>  <extension name="call_forward_enable"> <condition field="destination_number" expression="^7217([0-9]+)9$"> <action application="javascript" data="callForwardEnable.js"/> <action application="hangup"/> </condition> </extension> So the result would be something like: <extension name="call_forward_enable"> <condition field="destination_number" expression="^\*21\*([0-9]+)#$" break="on-true" /> <condition field="destination_number" expression="^7217([0-9]+)9$"> <action application="javascript" data="callForwardEnable.js"/> <action application="hangup"/> </condition> </extension> I can't seem to get it to work and my brain is melting trying to wrap my head around the different break values. Cheers, Matt

FreeTDM - destination_number empty on inbound call
by Christian Benke 09 Jun '11

09 Jun '11

Hi! My FS is connected to a plain BRI-line via a HFC-S PCI-card. On inbound calls i don't receive a dialed number. Please see the debug at http://pastebin.freeswitch.org/16456 for details. Do i have to fetch the DID from a variable before i can handle the call or is there some other problem, which i assume? Outbound calls work just fine btw. Best regards, Christian

originating a call from an outbound socket app
by Hector Geraldino 09 Jun '11

09 Jun '11

Hi all, I've been playing with FS around weeks, with some level of success. Right now I'm stuck trying to dial an extension, or to bridge a call to an external extension. Briefly, the scenario is the following: - Cisco CCM forwarding SIP calls to FS - FS in outbound mode, forwarding calls to a Java application using freeswitch-esl jar The java application answers the call, says a dialogue using TTS and receives input using DTFM or speech commands; all this is working pretty well. Now I'm trying to put this call in hold, originate a call to another extension and, depending on the result (call answered, not answered, destination user presses an specific number generating an expected DTMF), I need to bridge both calls and finish the session. I try several ways to get this done with no luck yet: using api originate to make the call with different arguments ({ignore_early_media, etc). I even tried to skip this step and just do the bridge between the inbound call and the external extension, but this didn't work either. I can't see any errors thrown by FS, and the result of the command is +OK, but nothing happens, the external phone never rings. The FS log only says: [DEBUG] switch_core_session.c:954 Send signal sofia/external/5655(a)192.168.8.1 [BREAK] <= this ext/IP address is from the inbound caller, not the one I'm trying to connect to. My first impression was that I might have something wrong with the originate/bridge parameters. I changed the dialplan XML file to just do the bridge, and it worked like a charm. <include> <extension name="test"> <condition field="destination_number" expression="6114|5121">  <action application="bridge" data="sofia/external/5562(a)192.168.2.14" /> </condition> </extension> </include> I don't know what path to follow here. I was unable to find relevant examples on google that guides me to solve this little issue. Can somebody please give me some advice? Thanks all, Hector

IP Whitelist
by Eric Beard 09 Jun '11

09 Jun '11

It seems I misunderstand the purpose of the acl.conf.xml file. What I want to do is create an IP whitelist, so only the IPs I designate get a response from FreeSwitch. I'd like to do this with FreeSwitch rather than a firewall. I have this in acl.conf.xml: <list name="domains" default="deny">  <node type="allow" domain="$${domain}"/>  <node type="allow" cidr="10.1.0.0/24"/>  <node type="allow" cidr="209.249.3.74/32"/> </list> I was assuming that this would only allow traffic from my local network, 10.1.0.0, and from the single IP 209.249.3.74 But while watching sip traffic, I saw an OPTIONS request from a different IP (sipvicious scan). Freeswitch happily responded to the OPTIONS with an OK. How can I configure it so that it ignores requests that are not on my whitelist? Thanks! ----------------------- Eric Z.

Response status from client
by Alessandro 09 Jun '11

09 Jun '11

Hi, I have two questions about FS: Question 1: i'm developing a custom client sip with pjsip. This client when receive a call that can't be accepted respond with status 603. I think that freeswitch filter this status. This is an example of desired behaviour: 1000@localnet_ip FS(ip:localnet_ip) 1001@localnet_ip INVITE ----------> INVITE ---------------> <-------------- trying<--------------------trying <-------------- 603<------------------ 603 ACK ------------> ACK------------------> The current behaviour of FS is: 1000@localnet_ip FS(ip:localnet_ip) 1001@localnet_ip INVITE ----------> INVITE ---------------> <-------------- trying<--------------------trying <------------------ 603 <-------------- 200 ACK------------------> <--------------------BYE I'd like to avoid the current behaviour. It's possible a kind of message status path trough? If the called party terminate the call before answering, FS send always to the calling partner 200 and BYE. First thought was related to the voice-mail. Now voice-mail is disabled but the behaviour is the same. Question:2 It's possible a custom Header pass trough in status response like trying or session in progress? I'm able to use custom header only on invite adding to invite a header with name like X-myheader. Any suggestion? Thanks Good Evening Alessandro -- Ing.

UUID_Bridge Fails But Reports +OK

Hello List , Good Morning. In my fight to get ESL & Python & Freeswitch all to behave properly i noticed a possible BUG ( need the veterans to confirm). Scenario : Originate & ValetPark () + MOH OR Just Park() , Both show the same problem. Codec G729 I Make another call: originate & park() codec G729 Now Python ESL Inbound Or FS Console : uuid_bridge uuid1 uuid2 +OK uuid Now one of the two things happen : 1) One the call gets connected hurray :) , Audio Perfect , etc. 2) The call gets dropped :( In both cases uuid_bridge reports +OK even in the case the call is dropped. Even if i Park() Both Calls using the dialplan XML ( NO ESL with those SYN/ASYNC Problems) I still get sometimes ( not always) a dropped call could this be related to the use of G729 ? I have lots of available licenses. Regards António Teixeira
