dp+ prefixed on From URI
by John Rose 18 Jan '11

18 Jan '11

Why does the chat API command prefix a "dp+" onto the From URI when I call the chat API? Here is an argument that I am using: "sip|+15186819448@65.41.13.124|external/sip:+12062990047@65.41.13.125|Test message." Then the From header: From: \"+15186819448\" <sip:dp++15186819448@65.41.13.124>;tag=FUetK564c4egm\\r\\n John

Usecure identification of Gateway (incoming call).
by Artur Cichocki 18 Jan '11

18 Jan '11

Hi. What is the proper way of gateway identification in incoming call? The variable_sip_gateway looks like directly taken from the sip_req_user (username from INVITE). Examples: I am using two FS, FS2 as a gateway for FS1. Gateway name "testgw", username "testuser", and a lua script dumping variables. Case 1: ======= Simple configuration according to FS wiki. Everything looks fine, incoming call from FS2: FS2: Registred as: Contact: "user" <sip:gw+testgw@212.180.x.x:5080;transport=udp;gw=testgw> FS1: variable_sip_gateway: testgw Case 2: ======= Configuration with added: <param name="extension-in-contact" value="true"/> FS2: Registered as :Contact: "user" <sip:testuser@212.180.x.x:5080;transport=udp;gw=testgw> FS1: variable_sip_gateway does not exist (!) Case 3: ======= Configuration from Case 1. I am using Linksys SPA adapter, calling FS1 directly by ip, using "gw+testgw" as a destination user/number. FS1: variable_sip_gateway: testgw (looks like serious security flaw) -- Artur Cichocki

RTCP Keep Alive issue - hangup after 60 seconds of silence
by Andy Ayers 18 Jan '11

18 Jan '11

Hi, Have encountered a problem recently where the company responsible for forwarding sip calls to my switch has started hanging up calls when there is more than 60 seconds of silence on one side of the call. As my service is primarily used for recording incoming messages, this means that any message being recorded longer than 60 seconds gets cut off. My provider says I need to configure freeswitch to send rtcp keep-alive packets to prevent them from hanging up the call. Can anyone tell me how I can do this, I've checked the docs and can't seem to find the right setting? Many thanks Andy

mod_callcenter related questions
by Weigel, Stefan 18 Jan '11

18 Jan '11

Hi all, I'm playing around with mod_callcenter and hitting some questions: * what means position and level in tier configuration ? Is it only related to queue parameter 'strategy' ? * having more than one agent in a queue logged in only the first agents phone rings for tier_rule_wait_seconds but the call is not directed to the next tier/agent logged in to the queue * is it possible to configure overflow destinations means if a call isn't answered in a certain queue it's overflowing to another queue ? Any help would be nice. Thanks in advance and best regards Stefan

Cisco Java phones crash when nonce count is incremented past 1 -- any ideas?
by Graham Saathoff 18 Jan '11

18 Jan '11

Hello all, I have several Cisco Java powered phones (7941, 7961, 7965) that repeatedly drop calls. The issue seems to be that once the phone attempts to update the nonce count to 2, it crashes and disconnects the call. Has anyone seen this behavior before? Any suggestions for how to fix this would be greatly appreciated. Thanks, Graham

Re: [Freeswitch-users] bridge a call to remote conference
by Madovsky 18 Jan '11

I did more tests, I can say that if the user bridged to the conference has the same HZ rate of the conference (even if the codec is different) so the sound is broken. ----- Original Message ----- From: Madovsky To: freeswitch-users(a)lists.freeswitch.org Sent: Sunday, January 16, 2011 2:33 PM Subject: Re: [Freeswitch-users] bridge a call to remote conference more weird, if I choose a codec from the sip phone based on 8000hz it doesn't work. it's like a rate conversion has to be forced to make the audio work on the conference bridge... ----- Original Message ----- From: Madovsky To: FreeSWITCH Users Help Sent: Sunday, January 16, 2011 12:10 PM Subject: Re: [Freeswitch-users] bridge a call to remote conference after some test I confirm that it should force to offer a codec at the same rate of the conference, example <action application="bridge" data="{absolute_codec_string=GSM,ignore_early_media=true}sofia/internal/${conference}"/> as GSM is a 8000hz code so it works now... thanks ----- Original Message ----- From: Steven Ayre To: FreeSWITCH Users Help Sent: Sunday, January 16, 2011 4:20 AM Subject: Re: [Freeswitch-users] bridge a call to remote conference Try answering the call before you enter the conference, possibly with a small sleep inbetween too.

Another: xml_curl vs Lua
by Saeed Ahmed 18 Jan '11

18 Jan '11

Dear all, i know that lua is preferable by FS devs and community, but here i want to ask questions particular to my use case *1. Current Setup* * *1.1 currently i am using xml_curl - for dialplan only 1.2 xml_curl.conf has two bindings so i am safe if first one dies 1.3 i am using apache + mono (.net) + mysql on another server (other than FS server) 1.4 Intel(R) Xeon(R) CPU E5420 @ 2.50GHz 8 core with 8 gm ram (for both FS and apache+mysql server) *2. Call Life Cycle* 2.1. call comes on internal profile 2.2. xml_curl ask xml from webserver 2.3 i do database query for each call and, return back possible supplier(s) based on dialed number and customer id 2.4 i return xml to bridge the call on external profile Questiosn & Concerns: 1. So with above setup i am not able to reach more than 60 cps (most probably issue with my xml_curl backend), so i am thinking to try LUA 2. but one point is clicking my mind that, in case of xml_curl the webserver can be on external server, and xml_curl conf could have primary and backup binding, can i achieve that in LUA too? 3. Is LUA still be usefull as i am not doing any ivr etc.. its just xml conf which i have to return. 4. xml_curl based setup has good feature that i can serve more FS servers, can i also do it in LUA? Please ask me if i miss some information Thanks

Correction, my fault it works with "^$" thanks ----- Original Message ----- From: Madovsky To: FreeSWITCH Users Help Sent: Monday, January 17, 2011 9:46 PM Subject: Re: [Freeswitch-users] empty var expression ok I understoo what's happened. weirdly with db app apparently if the result of a select is empty so it will be in fact never empty but a space will be. so <condition field="${redir_conf}" expression="^ $" break="never"> with a space between ^ and $ works ----- Original Message ----- From: Michael Collins To: FreeSWITCH Users Help Sent: Monday, January 17, 2011 7:21 PM Subject: Re: [Freeswitch-users] empty var expression Where is this variable getting or losing the "undef" value?
