How to set callback for subclass CUSTOM event in perl with module ESL::Dispatch?
by "Гришин В.С." 16 Mar '14

16 Mar '14

I have FreeSWITCH Version 1.2.22~32bit ( 32bit) on Centos 5.9 In directory /usr/src/freeswitch-1.2.22/libs/esl/perl is script dispatch.pl I changed it to see CUSTOM events and spandsp::rxfaxpageresult subclass events, but heither CUSTOM events hor spandsp::rxfaxpageresult subclass not captured. #!/usr/bin/perl use ESL::Dispatch; use Data::Dumper; my $daemon = init ESL::Dispatch({}); $| = 1; sub worker { my $self = shift; print "I'm a worker\n"; } sub heartbeat { my $self = shift; my $event = shift; print Dumper $event; } sub channel_hangup { my $self = shift; my $event = shift; print Dumper $event; print "DO SQL GOODIES HERE!\n"; } sub custom { my $self = shift; my $event = shift; print Dumper $event; print "DO SQL GOODIES HERE!\n"; } $0 = "ESL::Dispatch rocks!"; $daemon->set_worker(\&worker, 2000); $daemon->set_callback("heartbeat", \&heartbeat); $daemon->set_callback("channel_hangup", \&channel_hangup); $daemon->set_callback("custom", \&custom); $daemon->set_callback('spandsp::rxfaxpageresult', \&custom); $daemon->run; I need catch the evnet only subclass spandsp:: (https://wiki.freeswitch.org/wiki/Mod_spandsp#Events) into CUSTOM event.

DTMF
by Brian Chamberlain 16 Mar '14

16 Mar '14

Hi All, Is there a way to detect the dtmf mode on a leg of a call? At the moment we have a carrier who sometimes sends inband and sometimes sends 2833, sometimes proposes 2833 but only sends inband, etc... I've set dtmf-type on the profile in use with this carrier as none so whenever we send 183 or 200 freeswitch doesn't have any telephone-event in the SDP and the carrier sends inband. Its the only way I could guarantee consistent DTMF mode with this carrier. I have most cases worked out but I have an edge case where a customer is using a REALLY old PBX and needs inband and not 2833 When we send a call to this customer we offer 2833 in the proposal and the PBX sends back that it doesn't want any DTMF signalling which is correct. Unfortunately because I'm calling spandsp_start_dtmf even though there is no proposal from PBX freeswitch sends DTMF from carrier INBAND but also generates SIP info messages. This gives the dreaded double digit issue. If I comment spandsp_start_dtmf everything works great but I need spandsp_start_dtmf . Is there someway to detect that the dtmf-type is none on a channel and in that case don't call spandsp_start_dtmf or detect 2833 and do call it? I've been looking for variables I could check but can't find one.. I could drop these messages on our proxy but would prefer if there was a more elegant solution. Many Thanks for any assistance. Regards Brian

ZRTP SAS to non ZRTP call leg UA?
by Bill Ross 16 Mar '14

16 Mar '14

Hi; When a call is between a ZRTP UA and non ZRTP UA, with FS MITM, I want to give the user the SAS that the ZRTP call leg is using. I note there is a script: scriptd/lua/zrtp_sas_proxy.lua that is supposed to hook into the call flow by: <action application="export" data="nolocal:api_on_answer=luarun zrtp_sas_proxy.lua ${uuid}"/> This appears to display the SAS, and, I will add TTS for POTS phones. Q1: Where do I make the script install call above? Q2: Is there a better way, code? Thanks; Bill Ross

Clive, Are you sure that is all that you are changing? Clearly the one that authorizes successfully has Authorization: Digest username="095290110", realm="voip", nonce="60f381b0", algorithm=MD5, uri="sip:sip.kiwilink.co.nz;transport=udp", response="a00513b45bea998c2f5dcdc89e9d8194" in the first sip packet. The one that fails does not include the "Authorization" information in the initial packet. Without knowing anything else, I would have guessed that the one that fails has the gateway configured with <param name="register" value="false"/> I realized you have basically indicated that is not changing, but if there is ANY chance you are using separate configurations, I would check your sipinterfaces.xml Hth, Sean -----Original Message----- From: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Clive Lansink Sent: Saturday, March 15, 2014 5:21 PM To: Freeswitch users list Subject: [Freeswitch-users] Mistified by a registration issue Hello listers.

Freeswitch and Apple Facetime?

After reading this blog post: http://blog.krisk.org/2013/09/learning-stupid-nat-tricks-from-apple.html and http://blog.krisk.org/2013/09/learning-stupid-nat-tricks-from-apple.html and the last couple weeks worth of Week in Reviews(the SDP compression support). I started wondering what is left to be able to have FS support Apple Facetime.

Another external profile - NAT questions
by Javier Aristizábal 15 Mar '14

15 Mar '14

Hi guys, I have a server on AWS. And I need two IP address on my FS box, because my stupid carriers can't send the DIDs to the 5080 port anyway, on AWS I only can configure private addresses on my ethernet interfaces, so I have eth0: 10.0.0.97 and eth1: 10.0.0.164. And have two Public IPs associated with each of this Private IPs. On rtp-ip and sip-ip, I used the private ip, and for ext-rtp-ip and ext-sip-ip I use the public IP. On both external profile and another external profile. I have a nice carrier that can send DIDs to the port 5080. So I registered an extension, call to the DID:5080 and I get the call on the external profile and I get audio on both sides. But when I sent the DID:5060 to another external, I can't get audio. This is a test call :http://pastebin.freeswitch.org/22132 I appreciate any clue. Thanks Javier
