Call back from voice mail creates loop
by Tim St. Pierre 11 Mar '11

11 Mar '11

Hello, I'm trying to set up the option in voicemail so that users can return a call directly from VM. In my voicemail.conf.xml profile I have specified the dialplan as XML and the context as "internal", which is what I use for calls coming from our endpoints or authenticated users. In our internal dialplan, we do some pattern matching and call an appropriate lua dialplan script to do build a set of instructions. Problem is, the lua scripts are looking at the destination_number variable to decide where to send the call. This variable is still set to "voicemail" from when the user called into their voicemail. Shouldn't the voicemail app have set that to the number we want to call back? I used the info app to look at the variables, and I didn't see anything obvious. Is destination_number the correct variable to use in a lua script that generates a dialplan? -Tim

mod callcenter
by Sam 10 Mar '11

10 Mar '11

Hello, Was testing callcenter module and found out that at times it gives error " invalid application callcenter " and after reloading the module it works fine. Some time also happens that if I reload the module it do not reloads the parameters of the callcenter like the agents & tires. It just unload & reloads even if there are changes to the specifications of agents. Regds Sam

Virtualisation and freeswitch
by Grygoriy Dobrovolskyy 08 Mar '11

08 Mar '11

Hello list, le me introduce myself first, I am Grigoriy Dobrovolskyy currently working as voip administrator and call centeres integrator. I worked a lot with asterisk, i think Fs is a great software but not easy to learn. I have googled my question and did not found a clear answer. With what technology i can virtualise freeswitch without timer problems ? I know that i can use OpenVZ but it's more 'jail' then virtualisation. I heard that Amazon EC with High CPU instance works (confirm?) Can someone give me info of a succesfull installations with Conferences, Moh / mixing ? And a technology used ? Thank you.

Compilation with -march options
by curriegrad2004 01 Mar '11

01 Mar '11

Is compiling FreeSwitch with the -march option in gcc a good idea? Because I just compiled the latest git using the -march option targeted for a Pentium 3 Processor and it did seem to increase the performance slightly in switching calls and transcoding calls. So far I haven't seen any adverse effects of doing this, but I was wondering if anybody else out there is also compiling FS with a march option and saw some performance increase or adverse effects...

intercom in lua dialplan
by Helmut Kuper 23 Feb '11

23 Feb '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I try to intercept a call in lua script. For the intercepting extension I do this: if (dialed_ext:len()==6 and dialed_ext:sub(1,2) == "**") then uuid=api:execute("hash", "select/last_caller/"..dialed_ext:sub(3)) if (uuid and uuid:len()> 2) then session:setAutoHangup(false) session:execute("intercept", uuid) return end end This results to a hangup of the intercepting extension while intercepted extension hangs up (completed_elsewhere) and caller/originator's call is connected. FS logs shows this for the intercepting extension: switch_core_state_machine.c:189 sofia/internal_et/8000(a)spklw.x has executed the last dialplan instruction, hanging up. When I use the ACTIONS table like this: if (dialed_ext:len()==6 and dialed_ext:sub(1,2) == "**") then uuid=api:execute("hash", "select/last_caller/"..dialed_ext:sub(3)) if (uuid and uuid:len()> 2) then session:setAutoHangup(false) table.insert(ACTIONS, {"intercept", uuid}) return end end then intercept/pickup works fine. Is there a trick to get it work with "session:execute("intercept", uuid)" ? regards helmut -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk0+8DYACgkQ4tZeNddg3dyKwACeKR4lsxUv3G26pdNp8GGsbWNg /OIAn2EIl2Vq+qibtodGd9vjjLfqKv8s =2fTE -----END PGP SIGNATURE-----

xml_curl and gateways
by Peter P GMX 21 Feb '11

21 Feb '11

According to http://wiki.freeswitch.org/wiki/Mod_xml_curl I'v tried to set up gateways dynamically, but I do net get it to work: I always get : "Invalid profile" My assumptions for a right xml answer back to FS are as follows, but I think at least one of it is false: 1. ) I start with <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> 2.) I do not want to change settings, so I do NOT add a <settings> tag 3.) I want to enhance an existing profile, so I add a profile tag (<profile name='external'>) 4.) I assume that I can have an existing profile "external" in the xml conf files and can mix additional parts dynamically into the same profile 5.) Within the profile I want to add gateways, so I add a gateway tag (<gateways>) 6.) Then I add the gateways 7.) I add the closing tags Which one of the assumptions if wrong? The request I receive is as follows: {"key_name"=>"name", "action"=>"directory", "tag_name"=>"configuration", "key_value"=>"sofia.conf", "controller"=>"xml_curls", "hostname"=>"freeswitch", "section"=>"configuration"} I only answer once at startup with the follwing: <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> <profile name='external'> <gateways> <gateway name="freeswitch2"> <param name="username" value="1007"/> <param name="realm" value="192.168.0.56:5061"/> <param name="password" value="xxxx"/> <param name="proxy" value="192.168.0.56"/> <param name="expire-seconds" value="30"/> <param name="register" value="true"/> <param name="register-transport" value="tls"/> <param name="retry-seconds" value="30"/> </gateway> </gateways> </profile> </configuration> </section> </document> Does anybody have a correct XML answer for a gateway and can post it? Best regards Peter

Call Recording
by Jerry Richards 18 Feb '11

18 Feb '11

Does the *2 DTMF method still work for recording calls? I recall this working before without needing to make changes to the dialplan XML, but right now it does not appear to work on the Sep 20 Freeswitch trunk. Thanks, Jerry

Persistence BLFs (or: Dear PBX please remember the BLF state)
by Patrick Plattes 16 Feb '11

16 Feb '11

Hi List :-), I'm currently switching from Asterisk to FreeSWITCH. It's really hard work for an Asterisk user, but using Asterisk becomes more and more painful even for small installations (less than 100 sip users). I know FreeSWITCH is not a drop-in replacement for the Asterisk PBX, but I don't want to change the behaviour of the PBX for the users. It's a preconception in Germany that the American people like (especially for the X-mas time) kitsch. Everyone here know the American houses with a hole bunch of blinking lights. But those decorated hoses are nothing against our offices! Our phones have up to 136 lights (BLFs). You often have to wear sunglasses at the office ;-) A typical usage of BLFs is to check if an agent is a member of the queue. I've build a simple extension to add and delete a member. I can user "presence in" and "presence out" to enable or disable the BLF, but there is one big issue. After a reboot of the phone the the user is still a member of the queue, but the BLF is off. We are using hints at Asterisk to show the user if he is a member and it works even after a reboot - with "presence" at FreeSWITCH it works (of cause) not. Does anyone have an idea how to implement it? My current extension is just for testing and so I use mod_fifo. It shouldn't be a problem to use mod_callcenter. The phone calls "queue-the_name_of_the_queue-the_name_of_the_user@pbxdomain" eg. "queue-sales_de-1000(a)freeswitch.cust" So how implement BLF persistence?

I just downloaded and compiled the latest Git and a little after starting freeswitch I'm getting non stop the following: [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [140(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 [WARNING] sofia_reg.c:1247 SIP auth challenge (REGISTER) on sofia profile ‘internal’ for [thomas(a)76.XXX.XX.XXX] from ip 212.224.71.236 it's non-stop and doesn't let me do nothing else. After the first time I went on to vars and changed the 1234 password....restarted and same thing happened, I also try denying the ip on acl.conf (not sure if has something to do with it but gave it a try): <configuration name="acl.conf" description="Network Lists"> <network-lists> <list name="test2" default="allow"> <node type="deny" host="212.224.71.236" mask="255.255.255.0"/> </list> </network-lists> </configuration> Restarted the computer but nothing, he (thomas I guess) was back on my console. Any ideas??? p.s. My computer is on DMZ (I know DMZ is not ideal but is the only way I got to be able to connect to the internal profile from out of the office etc).
