SIP stack attacks
by symmetricone＠gmail.com Sept. 7, 2011

Sept. 7, 2011

Has anyone seen or heard of SIP stack attacks (e.g. stack difference or stack fingerprinting) being used in the wild? http://www.blackhat.com/presentations/bh-usa-06/BH-US-06-Scholz.pdf talks very briefly about the possibility of using implementation bugs in an attack. It seems to me that the most likely effect of such an attack would be to crash the SIP process on the UA (DoS), but authentication bypassing could also be possible if the attacker got lucky. If such an attack is possible (a big 'if'), I suspect it would be very hard to execute; the risk from such attacks appears low. To put this into context, I'm wondering how paranoid to be when configuring my Acme Packet SBC. It's possible to blacklist any endpoint which sends malformed SIP messages, but that seems like a bit of an overreaction. Cheers, Paul

Copying existing 15454 users to new node?
by paul＠timmins.net Sept. 7, 2011

Sept. 7, 2011

Is there an easy way to copy existing users to a new node, or do I have to have them create their accounts manually every time we turn up a node (or just delete their account and readd to all under network view?) I'm aware there's a way to do it with Radius but I'm not ready to have my transport network depend on the good graces of a reasonably proximate PC server.

seems that the dns is broken on the ilbcfreeware.org domain - I have no idea how to contact them since the site is offline.

How do you pull the other carrier's information to port

Just for everyone's benefit......you are referring to a SOA provider that can do the inputs into the NPAC LNP database for you......correct?

Either a 3rd party or directly with Neustar. Once you have access to a "system you can pull information on a specific TN as to what SPID they belong to. Then you will know what company to talk to, to get their ordering requirements. Thank You, Natalie Howard 1stel, Inc.

How do you pull the other carrier's information to port

In our case, we are Inter-Connected with CenturyLink. We typically do what your talking about when we are in the process of converting a Centurylink customer over to our service. In the last year Centurylink finally provided us with a web based Customer Service Record(CSR) system that give us access to the data your referring to. From there we plug the customer's info into Centurylink's other web based LSR system to submit our LNP requests. I hope this helps.
