nibble to update DB after hangup
by Muhammad Naseer Bhatti 19 Oct '10

19 Oct '10

Hello, I am using nibble_bill to bill a few calls. Trying to implement a scenario where I can update the database or CDR? after the call has been billed. Could not find this info elsewhere. Is there a way we can achieve this with nibble or do I have to run a script, to check balance before and after the call, and right after the hangup update the DB with new info? -B

FreeSWITCH HA question&talk
by Seven Du 19 Oct '10

19 Oct '10

Hi, I tested FS HA, it works like a charm. however, I'd like to talk about some more: I tested on my local computer by enabling tack-calls. make a call and kill FS, restart FS and execute sofia recover. 1) originate user/1000 &record(/tmp/blah.wav) Recover works, however, it overwrote the recording. Added RECORD_APPEND=true made it work. But for other APPs like socket, it might make a new socket to a outbound socket, can it send a var like channel_recovered so a outbound socket can aware of a recover? 2) call from 1000 to 1001 Recover works. If I also do uuid_record, the recording cannot recover. Seems there are no infos in sip_recovery table. Neither does record_session, though there's an entry in sip_recovery table. I guess it might be possible to get this work. If it can send a channel_recovered event, then it might be possible to continue the record in outside logic(say, event socket). 3) call from 1000 to a gateway outside (NAT-ed), leg-a can recover, leg-b failed with: 2010-10-16 10:28:17.162241 [ERR] sofia_glue.c:3190 AUDIO RTP REPORTS ERROR: [Bind Error!] I guess it is caused by NAT. (since I kill & restart FS manually, it may take 10 seconds). Is it possible to change the router settings? Or could FS send a re-Invite to re-establish media? Below are some fantastic thoughts: 4) N + M redundancy Default FS HA is designed to 1+1 redundancy, it might be interesting for N(active)+M(standby) in large farms. If one active FS fails, bind the float IP to a standby server and go. 5) N (N>2) servers without float IP Let's say each client UA register to 2 (or more) servers, If one server fails, a FS controller then re-call the client in an active call through a pair-server and the client responsible to hangup the originate call and automatically answer the new one. This need client support of course. :) -- Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

exec_after*
by Jeroen C. van Gelderen 18 Oct '10

18 Oct '10

Hi, My helpdesk extensions are recorded. When the recording is complete (after bridge) I want to run a script to create a ticket and attach said recording to it. Initially I tried to use [...] Dialplan: FreeTDM/3:1/ Action set(exec_after_bridge_app=system) Dialplan: FreeTDM/3:1/ Action set(exec_after_bridge_arg=/root/wav2ticket.php) [...] but this doesn't result in an invocation of my script and seemingly no helpful diagnostic messages. I changed to using <action application="set" data="api_after_bridge=system /root/wav2ticket.php ${recfile}"/> which DOES work. Can anyone clarify the difference between the two approaches?

problem when recording conferences
by covici＠ccs.covici.com 18 Oct '10

18 Oct '10

Hi. I am having a problem with conference recordings using auto_record. Now it does record, but with some users if the user is silent for a while, then the first so many milliseconds of his first word cuts off. Is this a function of the energe setting, waste setting or how else can I prevent this? Thanks in advance for any suggestionns. -- Your life is like a penny. You're going to lose it. The question is: How do you spend it? John Covici covici(a)ccs.covici.com

problem with freeswitch and Cisco 7960
by Michael W. Lucas 18 Oct '10

18 Oct '10

Hi, I'm using Monday's FreeSWITCH build, with a config originally loaded 19 August 2010. I'm working my way through the FS 1.0.6 book. I have two phones, one Zoiper soft phone and one Cisco 7960. Both register fine, and the Cisco can call Zoiper. Zoiper cannot call the Cisco, however. The Cisco phone sends its register requests from UDP port 50790. When FreeSWITCH sends an INVITE to the Cisco, it tries to contact UDP/50790, and the phone returns an ICMP "destination unreachable." This same phone is also registered to an Asterisk box. When I call that number, asterisk connects to UDP 5060 on this phone. The phone replies from a high-numbered port to 5060. It seems I need some option to tell FreeSWITCH to send the INVITE to 5060? Or am I missing something? Thanks, ==ml -- Michael W.

Binding to virtual interface (ipsec vpn)
by Nicolas Brenner 18 Oct '10

18 Oct '10

Hello everyone, I'm having trouble binding FS to another ip on a virtual interface (eth0:3). The virtual interface's ip address is the gateway to an ipsec vpn, and the only way to access this voip provider's sip server, is through the vpn. I tried setting up an additional sip profile, with rtp-ip and sip-ip as the virtual interface's ip, but when I do that, no packets are sent at all when trying to make a call with originate through the cli (according to tcpdump). I tried also setting ext-rtp-ip and ext-sip-ip to the same virtual interface's ip, but nothing happened, still no packets being sent (according to tcpdump) when trying to make a call. Finally I tried only setting ext-rtp-ip and ext-sip-ip to the virtual interface's ip, and leave rtp-ip and sip-ip to $${local_ip_v4}, then tcpdump started seeing some traffic (when trying to originate a call) which I was able to capture. When I loaded the trace on wireshark though, I noticed the source ip being used to send all the (sip) packets, is the one from eth0 (public ip), and not eth0:3's ip (private ip for vpn). Has anyone had any similiar experiences? how were you able to solve it? Thanks for your help! Nico

by John Carpenter 18 Oct '10

18 Oct '10

Hi, I am trying to bridge an incoming h323 call to an external SIP provider, I am using latest git release. If I use G729 codec I get message "Unsupported ptime of 2 on write Audio codec G.729{sw} for connection [0xb4c0ee10]" and call fails to connect. If I use ulaw codec call fails to connect with "Write PDU fail: no control channel" If I make a straight SIP to SIP call though same provider all work ok. I have posted log of call in http://pastebin.freeswitch.org/14216 because it is rather large. my h323.conf.xml file looks like this <configuration name="h323.conf" description="H323 Endpoints"> <settings> <param name="trace-level" value="10"/> <param name="context" value="public"/> <param name="dialplan" value="XML"/> <param name="codec-prefs" value="PCMA,PCMU,GSM,G729"/> <param name="use-rtp-timer" value="true"/>  <param name="rtp-timer-name" value="soft"/>    <param name="gk-address" value=""/>  <param name="gk-identifer" value=""/>  <param name="gk-interface" value=""/>  <param name="gk-retry" value="30"/>  <param name="faststart" value="true"/>  <param name="h245tunneling" value="true"/>  <param name="h245insetup" value="true"/>  <param name="jitter-size" value="60"/>  <param name="progress-indication" value="8"/>  <param name="alerting-indication" value="8"/>  <param name="endpoint-name" value="fs"/> <param name="fax-old-asn" value="true"/> </settings> <listeners> <listener name="default"> <param name="h323-ip" value="$${local_ip_v4}"/> <param name="h323-port" value="1720"/> </listener> </listeners> </configuration> And this is the log of the xml_curl dialplan that is executed <?xml version="1.0" encoding="UTF-8" standalone="no"?> <document type="freeswitch/xml"> <section name="dialplan" description="php dialplan"> <context name="public"> <extension name="normal"> <condition field="destination_number" expression="^(\d+)$"> <action application="set" data="bypass_media=false"/> <action application="set" data="proxy_media=true"/> <action application="bridge" data="sofia/gateway/arbinet-o/$1"/> </condition> </extension> </context> </section> </document> Any help will be greatly appreciated regards, John Carpenter
