[Security Issue][Need urgent comment]

Hi Users, I am using FreeSWITCH Version 1.6.19 git c540248 . today i noticed very weird issue, that i am getting an attack on one of my dev servers, that somebody is trying to make calls out of the box. And he is able to register the phone via "default" username(check via sngrep), i am using complex password and there is NO USER with name "DEFAULT" on my switch. I tried to register the default user with any random password and it allowed me to register on my softphone. I am really worried, and i can't believe that it's something at FS end. I am sure its some mistake, can somebody help me out please. Regards Abbasi

weird bridge dialstring

Hello guys, I've got a test box locally installed, with ip 192.168.2.201. This box has a VM running with FS with ip 10.0.2.15. And users are on network 192.168.2.X USERS(192.168.2.X)->DEBIAN HOST(192.168.2.201)-->FREESWITCH( 10.0.2.15/ext-sip-ip 192.168.2.201) I forwarded all packets to the vm, i can register without issues. these are the 2 registered users: freeswitch@jessie> sofia status profile internal reg Registrations: ================================================================================================= Call-ID: MTVjZTc4Zjg2MmJmNDU0ZDI1ZTRhZjkyZWE1NGI2NWE.

Re: [Freeswitch-users] What means f1 and f2 in Tone Segment spandsp
by Raimundo Pérez Nieves 26 Jan '18

26 Jan '18

Yes but I found f1=1 and f2 =2 or f1=-1 and f2=-1 in a tone segment, trying to match with a specific descriptor. So which value is matching?

FS weird issue with TLS/SRTP and xml_curl on windows
by Bipin Patel 26 Jan '18

26 Jan '18

hi, i have two instances of FS running on a windows server, one is used for routing to carriers and that uses xml files and that works fine, the second instance is set up to allow clients to register to it using tls and srtp and users are authenticated using xml_curl which calls a php script which inturn sends the directory users details on a register from a client. The problem is every few hours or so FS stops accepting new clients unless i restart the service, i check the php script and the webserver and those are running just fine so no idea whats causing FS to stop calling the script or something else. -- Regards, Bipin ------------------------------------------------------------------------

CPU for FS boxes. High freq.? or more cores? or more cache?
by Adam Raszynski 25 Jan '18

25 Jan '18

Hi I plan to buy some new servers to use as FreeSWITCH boxes Servers mainly bridge calls and proxy media from A to B. No special features, but they got a lot of traffic and customers require high quality of calls. What is the best practice in choosing CPU for FS boxes? I see different options: - high frequency (4GHz+) desktop CPU's like Intel i7 series - medium frequency Xeons/Opterons, but with large cache - low frequency Xeons/Opterons but with many cores Unfortunately I can't find reasonably priced CPU's that will have both high freq., many cores and large cache so need to pick what's the best What is most important performance-wise for low latency, high quality media bridging? More single core frequency? More cache? More cores? Kind Regards

Not trying second route on NORMAL_TEMPORARY_FAILURE
by Avi Marcus 25 Jan '18

25 Jan '18

I have a bridge string with failover of "route A| route B" but I found a place where it's not working. I have continue_on_fail=true in the A leg. originate_disposition is telling me SUCCESS even though bridge_hangup_cause is recording NORMAL_TEMPORARY_FAILURE and sip_hangup_disposition is recv_refuse So.. what's wrong? How can I make sure the bridge failover works? As far as I know, normally it properly fails over -- but I just saw this several times today. Thanks, -Avi Marcus

Clustered FS and gateways with outbound registration
by Tihomir Culjaga 25 Jan '18

25 Jan '18

Hi, i got a question regarding gateways in a clustered scenario... provider <> kamailio <> FS farm <> kamailio <> sip_users This setup is ok when you have gateways with no registration. But what in a case when you need to register your gateway with a remote provider (outbound configuration), how to handle it ? If we configure the gateways on FS every and each FS will try to register the same gateway... this will just end bad :=) any idea how to deal with that ? Regards, Tihomir.

Struggling with Audiocodes MP124
by Nandy Dagondon 25 Jan '18

25 Jan '18

Hello folks! I'm setting up an Audiocodes MP124 I bought at eBay to connect with FS 1.8 on Debian Jessie. It's quite a struggle just to get a dialtone! The AC registered with FS but there's no dialtone. I tried other settings e.g. Hunt Group, IP Profile, etc. but I can't seem to hit the target. There's too many parameters (perhaps a sign of a good product). I'm trying this forum if anyone had experienced with AC MP124. Just a hint, a light at the end of the tunnel to keep me alive. :-) Tks, /Nandy
