OT: Voice Equipment
by itservices88＠gmail.com Dec. 18, 2009

Dec. 18, 2009

Hi all, I am preparing for my CCIE Voice lab, which needs voice equipment hands on practice, and i don't have enough money to pursue that. Would it be possible if someone has spare phones like Cisco 7960g, PVDM modules, fxo/fxs VICs, mc3810 voice gateway, Digium T1/E1 card, 2621/3640 router or any other related equipment. I am in Pasadena, CA and can pick if available locally, or i would be happy to pay the shipping cost via paypal. Please send me any email off list. Thanks and appreciated. -aam

LERG Data
by jrandall＠comwave.net Dec. 16, 2009

Dec. 16, 2009

http://www.localcallingguide.com <http://www.localcallingguide.com/> is generally pretty good but compared against LERG information it is not always 100% current. I've compared LERG NPANXXs against LCG a few times and there are sometimes prefixes present in LERG that are not yet present in LCG. One thing that's great about this site though is that aside from NPANXX information you can also use the data on this website to establish local calling area maps between rate centres. This information is not even available through LERG alone.

Hi, I'm looking into adding SMS services to L3 and VZN numbers, and want to run my own message center and sip/smtp/whatever gateways, and hook into the cloud with a provider like syniverse. Tips, traps, tricks, and war stories welcome. Thanks, David

SMS receive security
by nicholas.hatch＠gmail.com Dec. 10, 2009

Dec. 10, 2009

Hi all, Reading the last thread on why SMS isn't/should be dead, I almost piped up with a thought before I realized I should probably check my head-sphincter interface, first. Many banks use SMS messages as an out-of-band authentication factor for online banking. (ie, they send a challenge code to the customers phone in response to an online banking request) If one assumes that cell phone SMS messages can't be intercepted out of the air by a forged device or through other means, they operate as a quasi-physical authentication factor, which is very valuable. This would be a strong use case for SMS over email or other general-purpose communication mediums where the password or other knowledge can be bootstrapped into access to the medium. However, I'm not so sure this assumption is correct. Does anyone have good references for the security of SMS? The most I've been able to find is this Slashdot article [1]. -Nick [1] http://it.slashdot.org/article.pl?sid=09/05/21/1858233

Faxing to the new DASH SBC's
by chris.ledford＠cnxntech.com Dec. 10, 2009

Dec. 10, 2009

We have started to experience faxing issues to the new Dash SBC's. In the traces we are receiving a new T38 Invite that was not there before and it is waiting for our Switch to decline it before it moves on and completes the fax. Is anyone else experiencing this? Are there any suggestions to correct from the switch side? If I turn T38 on then my other faxing paths die..... Thanks in advance, Chris Ledford NOC ATOG Engineer CCNA/CCSP/CVOICE A+/NET+/SEC+/LINUX+/MCPe

VoIP (SIP) to VoATM conversion
by brent＠overthewire.com.au Dec. 10, 2009

Dec. 10, 2009

Hi all, Hoping to tap the collective minds here. I am wondering how to best convert voice traffic from VoATM/VoDSL to VoIP (SIP in particular). Here in Australia, a lot of competitive carriers deliver ISDN (up to E1) over SHDSL tails with an IAD of some description (eg Verilink) on the end. We have access to SHDSL tails, but of course with IP overhead we cannot squeeze 30 channels down a 2M/2M circuit if we run G711. Does anyone have any idea on how best to scale a solution whereby we can remove the IP overhead but still use our softswitches (seems to me that a lot of the competitive carriers here are using ATM directly plugged into their older switches). How are others doing this and making it scale ?

That is why they have direct end-office trunks to nearly everywhere. How does the termination architecture work? I would assume it's like any other large CLEC and/or IXC: by default, they connect to a POI and have tandem groups from there, and also ride their own network to select end-offices in which colocate equipment for the purpose of generating UNEs, when/if there is switching equipment there. -- Alex Balashov - Principal Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops

Guys: I know few months back there was a buzz about the Gotomeeting and other free conferencing numbers being dinged-up for very high per min rates. Has anyone had issues with Providers like Level3 charging high rates for these conferencing numbers?
