Authenticating end points by IP
by Ahmed Naji 22 Dec '09

22 Dec '09

People, Please do excuse me if this is a FAQ. I've so far not worked out a way to implement IP authentication effectively. I have a number of gateways/end points/...etc. hitting the switch without registration and originating calls to a number of upstreams I have configured. So far, everything is smooth and FREESwitch is legendary in every way. Over 10,000 simultaneous sessions at 120cps, on a dual-Xeon machine running CentOS and CPU usage is barely a blip. My problem is authentication. I need a method to authenticate end points based only on their IP addresses. I am currently filtering access through the firewalls, but I would really like to delegate this task to FS in prep for an SBC setup I'm working on. If I remove the firewall filters, then anyone is able to get in. I could't workout precisely how ACLs work in FS from the WiKi and the documentation, and I haven't been able to make sense of how Digest functions either. Can anyone shed some light on those two areas ? I would like to really get to the bottom of this and update the WiKi pages with the working setup once done. Regards, Ahmed. -- Ahmed A.

How to debug TLS handshake errors?
by Yehavi Bourvine 22 Dec '09

22 Dec '09

Hello, I am trying to debug a TLS handshake error between FreeSwitch and some ATA. When setting the loglevel to 9 I get only a message that TLS handshake failed. Is there some other debug command to show what happens during the TLS handshake process? Thanks! __Yehavi:

Re: [Freeswitch-users] [Freeswitch-dev] "a1-has" param in gateway setting

I'm not too sure you can put an a1-hash on outbound auth. /b On Dec 22, 2009, at 11:26 AM, Babak Karvandi wrote: > Hi, > > Does any body know or has test the "a1-hash" parameter with gateway > setting?

PSTN-to-Internal Call Does Not Get Routed to Voice Mail
by Jerry Richards 22 Dec '09

22 Dec '09

I have a Freeswitch PBX server with an installed Sangoma A101D card connected to a PRI. Most everything works okay, however when I get an inbound call from the PSTN, if the call is not answered within about 12 seconds, the call ends (so it doesn't go to voice mail). If I make a call from one internal phone to another, then it will go to voice mail after 30 seconds. How can I get the external call to route to voice mail after 30 seconds? I put a new 11595 log into the pastebin. Do you know any Freeswitch setting that might cause this? If this issue has been addressed before, what string should I use to search for it, because I can't find it. Thanks, Jerry

Building on Windows
by Dave Stevenson 22 Dec '09

22 Dec '09

Hi, I'm probably going to regret this - I'm not sure that I'll be able to do this without a lot of pain (nothing to do with FS - more my lack of ability with Visual Studio), but......, I want to try building FreeSwitch from source rather than using the pre-built binaries. I have a couple of initial questions that, hopefully, someone can answer please ? 1. I only have Visual Studio 2005 and don't see an upgrade to 2008 on the horizon for me. Having downloaded the SVN, I see there is a VS 2005 Solution, but it is marked as "Unsupported", although the Wiki says that you only need VC++2005. What does "unsupported" mean in this context ? I guess that support for VS2005 is being dropped, but is the VS2005 Solution still being maintained, and if so, for how long? I'd hate to get into the build thing and then find that I was stalled when VS2005 support was dropped altogether ? 2. The whole SVN thing is new to me but I've worked out that I need an SVN Client on Windows to work with the source. Can anyone recommend the best (free) SVN Client for Windows to use with FreeSwitch. I have installed TortoiseSVN - a Windows Explorer Shell that looks pretty and seemed to work on my first build but it's not command line based so some of the tips given in the Wiki like "make current" and "make sounds" may be more awkward to achieve. Is anyone else using Tortoise and/or can give some tips on which SVN client to use ? 3. I built 15979 last night (with VS2005) and got some warnings, with data type conversion - is this a known issue under Windows ? 4. There was one fatal error in the build of mod_opal (missing file) (Some examples of the warnings and the error are shown below :-) 5. How do I specify which options (e.g., mod_flite, to be included iin the build. 6. How do I build the sounds etc. ?

by Edmar Cruz 21 Dec '09

21 Dec '09

Hi Sir, How can I allow international calling in the dialing plan but for select accounts only? For example i want to restrict 8555555 to call this ip address 182.138.252.12 using the default configuration.. Does this command should be put in the default.xml or in the default folder and the filename is 00_restict.xml? <extension name="dialsample"> <condition field="destination_number" expression="^(8555555)$"\> <action application="set" data="effective_caller_name=${effective_caller_id_name}"/> <action application="set" data="effective_caller_number=${effective_caller_id_number}"/> <action application="set" data="hang_up_after_bridge=true"/> <action application="bridge" data="sofia/default/$1(a)182.138.252.12"/> </condition> </extension> When i tried this command both of them nothing happen 8555555 can call 182.138.252.12 i want it to restrict this account for not calling 182.138.252.12.. Please help..

Skypiax: Skype account frozen
by 大泥人 21 Dec '09

21 Dec '09

Hello, I noticed some guys had develop the Skype module while there is a policy from Skype(Ulimited call planso call FAP: ):"Each subscription is to be used by one person only and is not to be shared with any other user (whether via a PBX, call centre, computer or any other means)" , which means once you use Skype unlimited calls plan into PBX, Skype will frozen your account without any money return. That's a big risk for anybody to use Skype unlimited call plan. My question is how do we avoid such kind of risk?

ACLs through proxy
by Bill W 21 Dec '09

21 Dec '09

Hi All, I have a FreeSWITCH cluster behind an OpenSIPS proxy/load balancer, and I'd like to be able to use the auth-calls feature in my sip profile in conjunction with the <param name="auth-acl" value="1.2.3.0/8"/> parameter in the directory. In addition to running the INVITEs through the load balancer, I also need to run the REGISTERs through the load balancer because some of my endpoints are behind NAT firewalls, and therefore won't accept incoming calls from IPs other than the IP they registered to. INVITEs from the cluster going to registered endpoints are sent back through the proxy, thereby solving the NAT problem. However, having the proxy in the path effectively negates using IP based ACLS. The functionality I require is as follows: 1. Only allow registration if the endpoint IP matches it's own unique acl CIDR (specified in the directory). 2. Only accept INVITEs from endpoints that authenticate AND match the acl CIDR (again, specified in the directory). Does anyone have any recommendations on the best way to get the auth-calls functionality using an IP other than the IP of the last hop? If not, how hard would it be to add a feature to the auth-calls parameter to accept a channel variable from which to obtain the actual endpoint IP? Thanks! Bill
