What does an ALG actually do?
by johnl＠taugh.com March 6, 2013

March 6, 2013

I realize that an ALG is a hack in a router that is supposed to allow SIP packets to go through a NAT router. I also realize that for modern SIP equipment, ALG usually causes more problems than it solves, and that it's described in RFCs 2663, 3424, and others. What I can't find anywhere is what a SIP ALG actually does to the packets. Is that written down anywhere, or is it just network folklore?

Network Security Audit
by dwhite＠olp.net March 6, 2013

March 6, 2013

I have been asked by management to find options to bring in an external auditing company to evaluate our network and provide appropriate recommendations. We are a small telecommunications company looking for firms with experience in Voice (VoIP) security audits, as well as general security experience appropriate for a Broadband ISP, with an internal corporate network. We're located in the southern US (Oklahoma). Public and private recommendations are welcomed. Thank You, -- Dan White

VoIP traffic survey
by jra＠baylink.com March 5, 2013

March 5, 2013

----- Original Message ----- > From: "Frank Bulk" <frnkblk at iname.com> > My apologies, I'm not following you here -- can you give me an example > of a TDM traffic (i.e. T-1 or DS-3) flowing over the Internet? Didn't say it had to be TDM. I am a VoIP end-user. I pick up my desk phone to make a call, and my PBX routes it. It might go: * To a local PSTN gateway, and out over traditional TDM (or analog) lines, or * To a commercial gateway provider, or * Direct to the other end's PBX as a 'native' VoIP call In either case, it might get there over * Private, dedicated IP networking, or * The Internet. The 6 sextants are "who operates the gateway" multiplied by "who owns the wires I use to get there". Cheers, -- jra -- Jay R.

AT&T Wireless call routing problem / contact
by nathana＠fsr.com March 4, 2013

March 4, 2013

Hey, Does anyone know anyone / have any contact information for ATT Wireless engineering, or (even better) is there an ATT Wireless engineer who would mind contacting me off-list? We're seeing a problem with call routing to certain NXX, but only when forwarding calls to TNs in that NXX. Thanks, -- Nathan Anderson First Step Internet, LLC nathana at fsr.com

Issue with one touch call list buttons on Polycom 501/Broadsoft
by RDawson＠alliedtelecom.net March 1, 2013

March 1, 2013

We picked up a customer that had a number of 501s. I downloaded the latest firmware, bootrom and configs and created a new device type. Phones boot, provision and register fine however there is no icon displayed for the registered lines and the one touch call list feature does not work. If I boot against the vanilla configs everything is normal, as soon as I boot against the "templated" configs it breaks. I have literally stripped everything out of the configs that I can, they have basic registration information at this point. I have made up dozens of Polycom configurations in the past and never seen this issue. Of course since the device has been out of warranty since 2007 I have to open a PPI ticket so I just wanted to see if anyone may have seen something similar in the past. Thanks, Rob

You MUST attend SIPNOC. You SHOULD propose a presentation.
by lindsey＠e-c-group.com Feb. 27, 2013

Feb. 27, 2013

You are REQUIRED to attend SIPNOC 2013, April 22-25, 2013 in Herndon, VA. It's a lot like voiceops, but with colocated participants. If an asteroid were to hit SIPNOC, the WebRTC Apocalypse would immediately ensue. In this document, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in BCP 14, RFC 2119 and indicate requirement levels for compliant SIPNOC attendees. You MAY send a delegate to represent you at other technical conferences (or user group meetings) scheduled to occur at the same time. Watching a live stream of other concurrent events is OPTIONAL. You SHOULD propose a talk to present at SIPNOC to explain some interesting topic or challenge you've overcome. The talk MUST NOT be a marketing talk (except to brag on your own superpower VoIP skills.) It is RECOMMENDED that the talk include in-depth technical content. Acting in a effortlessly nerdy manner while at SIPNOC is RECOMMENDED; fortunately, 98% of attendees have accomplished this in past years. 2% had to apply effort to fit in. Talking smack about products and vendors or is OPTIONAL. It is RECOMMENDED that some technical representatives from vendors be sent to participate. The following vendors MUST send representatives to appear in person, because their products will surely be discussed: Sonus Snom Sansay Sangoma Polycom Metaswitch Grandstream EdgeWater Digium Cisco BroadSoft Adtran Acme Packet Aastra This email MUST NOT be construed as authorized communication of SIP Forum, the SIPNOC Program Committee, Marc Robins, or any of his cohorts or colleagues. This email does not express the opinions of my clients or my employer (unless they want correct opinions).

Fwd: [Sheflug] Zero-day rootkit?
by ghenry＠suretec.co.uk Feb. 22, 2013

Feb. 22, 2013

Hi all, Anyone seeing this on any of your softswitches/SBCs/SIP Proxies that are built on Linux kernels? Thanks. ---------- Forwarded message ---------- From: Chris J <cej at nightwolf.org.uk> Date: 21 February 2013 19:25 Subject: [Sheflug] Zero-day rootkit? To: sheflug at sheflug.org.uk Just a heads-up in case it's not been seen. The last couple of days I've seen blogs and forums light up with news of an active zero-day attack - the actual attack vector is currently not known, which makes this more worrying than most. Some folk are placing the blame on SSH, others on cPanel, but really, no-one currently knows. Typically it's been Redhat or CentOS machines affected, although I've seen (unconfirmed) anecdotes on forums that Debian has also been affected. You'll know to be suspicious if you have a file, libkeyutils.so.1.9, on your box, most likely under /lib (but could be elsewhere). The latest "good" version of this file is 1.3... It's also curious that most of the talk is on forums. I haven't seen anything from the distributions about this. Relevent links and more info: http://blog.solidshellsecurity.com/2013/02/18/0day-linuxcentos-sshd-spam-ex… http://blog.configserver.com/index.php?itemid=716 http://www.webhostingtalk.com/showthread.php?t=1235797 A google for libkeyutils.so.1.9 brings back other various forums, etc... Don't know if anyone's got more solid information on this?
