TCP ACK Ping
by Spencer Thomason 14 May '13

14 May '13

Hello all, I have been doing some experimentation migrating several phones from UDP to TCP SIP to address MTU issues with BLF NOTIFYs. Mostly everything is working great except for Polycom handsets running UC v4. (Note that I did not test any v3 phones.) The phones are behind NAT and Freeswitch is on a public IP. The phones periodically send a TCP ACK ping to Freeswitch which goes unanswered and then phone then tears down the TCP connection. I'm not at all a TCP expert but should Freeswitch be responding to this unsolicited ACK? I have tried in vain to disable these keepalives from the Polycoms. Has anyone else encountered this behavior? Thanks in advance, Spencer

Advice using mod_curl
by Saugort Dario Garcia Tovar 14 May '13

14 May '13

Hi, I have lua script. the script is similar to the one in http://wiki.freeswitch.org/wiki/Mod_curl (lua usage) The script access a web service and get some data. The script work fine for my needs. However, sometimes when the script access the web service take several seconds to get the data, and the caller ear silence. Is it possible to play a sound file as long the script try to get the data from the web service? -- Atentamente, *Dario García* Consultor. CCCT, Nivel C2, Sector Yarey, Mz, Ofc. MZ03a.

Idiot question concerning internal calls
by Alex Lake 14 May '13

14 May '13

I've just discovered a yawning hole in my knowledge of Freeswitch... When I make an internal call, I would like to be able to set variables that are originator specific. I had previously done this in the directory part of conf with things like this: <include> <user id="9903301"> ... <variables> <variable name="tenant_id" value="9903"/> <variable name="a_ext" value="301"/> <variable name="accountcode" value="301"/> <variable name="user_context" value="dp9903"/> <variable name="internal_caller_id_name" value="Internal from x301 alex"/> </variables> </user> </include> But when I try to extract those variables in a lua script (eg. the extension handling "201"), they don't seem to be there. It's as though they weren't exported from A-Leg to B-Leg. What am I missing? How can I arrange for variables set in the <user> to be readable in the b-leg dialplan?

without having more information on the rest of your dialplan, i just will shout out: export, check the export variables or dialplan app, i use it in various scenarios when I have to make sure variables are available in all cdrs. ----- Original Message ----- From: "Alex Lake" <alex(a)digitalmail.com> To: "FreeSWITCH Users Help" <FreeSWITCH-users(a)lists.freeswitch.org> Sent: Martes, 14 de Mayo 2013 14:07:53 Subject: [Freeswitch-users] Idiot question concerning internal calls I've just discovered a yawning hole in my knowledge of Freeswitch...

Changes between versions
by Alex Lake 14 May '13

14 May '13

Is there a clever way in which one can use git/github to tell me (in human readable terms!) all the changes between version A and version B of Freeswitch?

Limit concurrent calls
by Tomasz Szuster 14 May '13

14 May '13

Hello, I've set up limit for outgoing calls using http://wiki.freeswitch.org/wiki/FS_weekly_2010_12_01, especially by adding: limit hash fraud_protection calls_max_intl 32 !NORMAL_TEMPORARY_FAILURE to the dialplan. When I created second dialplan with different call_max_intl value freeswitch did not get it. It has still remember call_max_intl 32 from first dialplan. At console I've got: *Usage for fraud_protection_calls_max_intl is already at max value (32)* I've also try with: <action application="limit_execute" data="hash outbound gateway 12 bridge sofia/gateway/gateway/$1" /> Result was the same as for limit hash. My goal is to create dialplans with different calls max where calls max value are treated separately. Can you please advice how to proceed, where to look ? -- Regards. Tom

Dynamic external profile proxies
by Oleg Stolyar 13 May '13

13 May '13

I am very new to FreeSWITCH and would like to use it as a SIP load balancer to other (media) FreeSWITCH instances. I was thinking of using the external SIP profile and bridging incoming calls to the media instances of FreeSWITCH using some rotation mechanism (round robin, least busy, etc) My question is this: Would I need to have a separate SIP profile for each media FreeSWITCH server or can I define a profile in such a way that I can dynamically specify the proxy for each call? Thank you *Oleg*

Recommendations for Trunks from Hawaii?
by Jeff Bernhardt 13 May '13

13 May '13

Not Freeswitch specific, but... We have a couple Vitelity DIDs we use for testing, but the latency on them is fairly bad. We figure this is just because of physical distance... we're in Hawaii and Vitelity is I believe in Denver (at least that's the ip we connect to). Does anyone have recommendations for any good trunks that might be located somewhere closer (California)? There are plenty of companies here and there, but what are people using that might meet our needs? Thanks.
