where to find available dark fiber maps and info
by eric.fort＠gmail.com Oct. 22, 2012

Oct. 22, 2012

I'm presently looking into the feasibility of bringing connectivity and bandwidth into undeserved rural markets and looking for places where dark fiber may already be accessable and available. Thus far in speaking with carriers it seems many if not most of them do not want to bother breaking into / breaking out unused dark fiber on their routes and only seem to know of their own routes but not the routes of others. Wheonsultingre can I find maps and such of where dark fiber exists, and who to negotiate with for it's use. I'm looking at / for both long haul routes that would give access into major NAPs & MAEs but also fiber laid around various (rural) towns and for instance between various tandems.

Canadian TFN Calls
by shripald＠gmail.com Oct. 19, 2012

Oct. 19, 2012

Hi all, I have an issue that seems to have arisen (perhaps recently), that i'm unsure of how to resolve. We have a few customers in the Toronto, ON area where the outgoing CLID set as a Toronto TN (sourced from bandwidth.comi believe). when these customers dial canadian Toll Free numbers, the TFN provider rejects the call. we send these calls our our level3 EVT trunk. Level 3 states that they only support canadian TN's calling Canadian TFN's as "best effort". we have the same issue sending the calls out Bandwidth, where they might likely send the call out Level3 as well. we have the same issue sending the calls out windstream. has anyone seen this issue as well? i'm going to try a few more carriers. thanks, shri

oops, didn't finish my though. i'm assuming there is no way to differentiate between a US TFN and CANADIAN TFN right? thanks srhi On Oct 19, 2012, at 11:28 AM, Shripal Daphtary <shripald at gmail.com> wrote: > there's no way to differ > > On Fri, Oct 19, 2012 at 10:25 AM, Shripal Daphtary <shripald at gmail.com> wrote: > Thanks.

Number Mangement

Just curious if anyone was aware of a web based number management system. Just something we could use to help us keep track of where our assigned numbers are used. Something PHP would be prefered. Nick Olsen Network Operations (855) FLSPEED x106

SIP trunks to a Zultys MX250 anyone?
by ssrinivasan＠telesphere.com Oct. 16, 2012

Oct. 16, 2012

I have a customer opportunity to deliver SIP trunks to a Zultys MX 250 IP PBX. In the world of IP PBXs, that name is not one I run in to a lot. Does anyone have experience with this box? SIP implementation quality? If you have done this, any obvious, basic issues? My SIP delivery mechanism would be via ACME Packet.

DDOS attacks against ITSPs
by ryandelgrosso＠gmail.com Oct. 15, 2012

Oct. 15, 2012

All, I am relatively certain most of you have heard about the issue CallCentric had experienced recently where they came under a significant DDOS attack. My question to the community at large is, who here has been down this road and been attacked; and what was the signature of that attack. I am sure your are not alone and we could probably all do fairly well to compare notes on the topic. This year alone we have seen at least 7 different flavors of DDOS attacks aimed at our resources some impactful some not, and I would be extremely interested in comparing notes with anyone else (especially callcentric engineers) who are interested in hoping to share information and perhaps prevent the next major incident. Feel free to respond on or off list as you see fit. -Ryan

Main number fail-safe solution for small ITSP
by carlos＠televolve.com Oct. 15, 2012

Oct. 15, 2012

I'm curious how other small VoIP providers handle having a fail-over for their main (support) phone number in case their entire infrastructure is unable to take calls. I know we all build in redundancy, but for the big what-if scenario where nothing is available and the calls fail, you still need to take your customer support calls. We have one carrier who does PSTN failover, but they're far from our primary or an ideal carrier for us. None of our major origination providers do this. -- Carlos Alvarez TelEvolve 602-889-3003

Number Portability Within a Carrier
by beckman＠angryox.com Oct. 11, 2012

Oct. 11, 2012

So there are some pretty big Tier 1 names in the DID/telecom world: Level3, Verizon, Bandwidth.com. Many resellers resell the DIDs they get from these bigger companies. The problem is that the Tier 1 company shows up as the "owner" of phone numbers that we get from our Tier 2 or even Tier 3 providers. That's all fine and good, but the problem is this: Me ------> Tier 2 provider --> Tier 1 provider / Not Me --> Tier 2 provider / When someone submits a request to port a number, and they port it to a different Tier 2 provider that gets its numbers from the same Tier 1 provider, I have no way, not even with an LNP dip, to find out that it was ported, that the owner had changed. I'm pretty sure Tier 1 providers don't have an API or any way that I might be able to find out that they moved a number from one of their direct customers to another. Am I wrong? So how do we deal with this? How do we find out, in a definitive and authoritative and programmatic manner, when a number we think is ours is ported away?

Push DTMF to IAD after call answered
by RDawson＠alliedtelecom.net Oct. 3, 2012

Oct. 3, 2012

I need to be able to initiate a call to an IAD and then automatically send some DTMF tones to it after it picks up. This is on Broadworks, currently using a SPA-2102 but whatever works is fine. Thoughts? Thanks, Rob
