Questions about att_xfer
by Anatoliy Kounitskiy 28 Aug '09

28 Aug '09

Hello everybody! I have few questions about the att_xfer application. First, what i want to accomplish is: user A calls user B, after that user B makes attended transfer to user C. In the dialplan i have: <context name="vpbx"> <extension name="local_number"> ... <action application="bind_meta_app" data="1 b s execute_extension::dx XML features"/> <action application="bind_meta_app" data="2 b s record_session::$${base_dir}/recordings/${caller_id_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/> <action application="bind_meta_app" data="3 b s execute_extension::cf XML features"/> <action application="bind_meta_app" data="4 b s execute_extension::attented_xfer XML features"/> .... </condition> </extension> So when user B answers the call, he sends *4 and the extensions for the attended transfer is started - the usual - plays message and read the input dtmf: features.xml ... <extension name="attented_xfer"> <condition field="${toll_allow}" expression="local"/> <condition field="destination_number" expression="^attented_xfer$"> <action application="info"/> <action application="read" data="3 4 ivr/ivr-enter_ext.wav attxfer_callthis 30000 #"/> <action application="set" data="call_timeout=15"/> <action application="att_xfer" data="user/${attxfer_callthis}@${domain_name}"/> </condition> </extension> ... To this problems everything is perfect. But here comes the questions, so if you can give some tips would be great. 1) when user B enters the extension number of C - the C's phone starts ringing in the tcpdump i can see that the phone is sending 180 ringing, BUT user B does not hear the ringing. 2) as mentioned in the http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_att_xfer quote: "If the other leg is a voicemail or doesn't answered you can hangup that leg by pressing dtmf # (fixed in r14438) " It doesn't work. The option 0 is working even before C answering the phone - after he answers it's a threeway conference :) - i like this feature. I'm using FreeSWITCH Version 1.0.trunk (14633M) Also I tried to set call timeout to see if I can go back the user A, who is listening to MOH - no luck here. Probably I'm missing something. Tried to look in the source of att_xfer to understand why the feature i want is not working - but it seems my C/C++ skills are not so good, as i want :( . Thank you in advance, Anatoliy Kounitskiy

timeout while waiting for CF_BRIDGED flag
by Tamas Cseke 28 Aug '09

28 Aug '09

Hello, we have a strange problem, sometimes calls are hung up with DESTINATION_OUT_OF_ORDER cause. I added some extra log lines, and it turned out that switch_ivr_bridge.c:140 a timeout occurs while waiting for CF_BRIDGED flag switch_channel_wait_for_flag(chan_b, CF_BRIDGED, SWITCH_TRUE, 10000, chan_a); returns SWITCH_STATUS_TIMEOUT As far as I understand the flag on B channel is set in another thread, so maybe it happens slow sometimes. We are using r14144. I know it is quiet old, but maybe this code hasn't changed since them Do you have any idea, what could cause this? Do you think it is a bug? Thanks in advance, Tamas

Authorizations when using DNS SRV bug?
by Carlos S. Antunes 28 Aug '09

28 Aug '09

Hello! I am using Callcentric for my tests and have observed what appears to me a possible bug in the way Freeswitch handles DNS SRV records. Callcentric uses DNS SRV records as a way to direct traffic to their SIP server. A 'srv' 'dig' of '_sip._udp.callcentric.com' returns: _sip._udp.callcentric.com. 10025 IN SRV 20 7 5080 alpha6.callcentric.com. _sip._udp.callcentric.com. 10025 IN SRV 20 7 5080 alpha7.callcentric.com. _sip._udp.callcentric.com. 10025 IN SRV 20 7 5080 alpha1.callcentric.com. _sip._udp.callcentric.com. 10025 IN SRV 20 7 5080 alpha3.callcentric.com. Based on this information, Freeswitch appears to correctly round robin all available IP addresses except in a particular situation: in the middle of authorizations. For example, in a registration, Freeswitch send a packet to alpha1.callcentric.com. Callcentric then challenges Freeswitch with a Proxy Authorization request. Freeswitch then sends the packet with the requested credentials but not necessarily to alpha1.callcentric.com! In many cases, instead of sticking to the 'challenging' server, Freeswitch round robins and sends the second packet to, one of the other servers. This continues for a little while and eventually, simply by luck, the second packet is sent to the 'challenging' Callcentric server. Shouldn't Freeswitch stick to the same server when challenged for credentials? Is this a bug? Is there a way to make Freeswitch behave differently? Thanks! Carlos Antunes Nowthor Corporation

The $session object represents an existing channel and therefore it uses Dialplan apps. Originate is an API, that is, it is a command that you type at the CLI. You need an API object to use originate from a script: my $api = new $freeswitch::API(); my $res = $api->executeString("originate user/1010 &bridge(user/1000); What kind of application are you developing? I'm curious why you need an originate to create a whole new call. -MC > On Thu, Aug 27, 2009 at 9:46 PM, Michael Collins > <msc(a)freeswitch.org> wrote: > > > On Wed, Aug 26, 2009 at 9:38 PM, lakshmanan <lakindia89(a)gmail.com> > wrote: > > When I give the following from the command line it calls to 1010 > extension > and once answered, it calls to 1000 and bridge the connection. > originate user/1010 &bridge(user/1000) > But I want to do this in perl.

I assume you asked for port 5062 since I do not have any traffic on 5060 (I have one IP and my internal sip port is 5090 and external 5080). If you need additional info I'll provide it.

Mixing mod_curl_xml dynamic dialplans and static ones
by Greg Thoen 27 Aug '09

27 Aug '09

I have mod_curl_xml working, but I also have several static dialplans in dialplan/public/ and I can't seem to get it to search those if my php generated xml page does not return a result. I know in the static public.xml there is this <extension name="unloop"> <condition field="${unroll_loops}" expression="^true$"/> <condition field="${sip_looped_call}" expression="^true$"> <action application="deflect" data="${destination_number}"/> </condition> </extension> Do I need my php page to generate something like that so it will continue looking in the static pages if it does not find a match in the xml_curl dynamic dialplan? I don't know if I have given enough data for someone to point me in the right direction... This is in the console when I have mod_xml_curl enabled: 2009-08-27 16:39:52 [INFO] mod_dialplan_xml.c:252 dialplan_hunt() Processing ->15854199896 in context public Dialplan: sofia/internal/585xxxxxxx(a)208.34.86.39 parsing [public- >curl_test] continue=false Dialplan: sofia/internal/585xxxxxxx(a)208.34.86.39 Regex (FAIL) [curl_test] destination_number(15854199896) =~ /^(18775844111)$/ break=on-false 2009-08-27 16:39:52 [INFO] switch_core_state_machine.c:136 switch_core_standard_on_routing() No Route, Aborting -- Greg
