Grandstream FXS Gateways
by colton.conor＠gmail.com March 17, 2015

March 17, 2015

Does anyone use the Grandstream FXS gateways like the GXW4008? It has 8 FXS ports, 1 FXO port, 2 Fast Ethernet Ports, and cost $156 new from distribution. We are having more clients that need 2 to 8 phone lines. We typically use Adtan 900/900e series gateways, but these gateways new cost 3 to 4 times more than this Grandstream unit. One thing we don't like about the Adtran units is they have built in T1/PRI ports which we rarely use. I am wondering how good is the Grandstream SIP stack? How good is its debug options? Does it have any voice quality monitoring tools like Adtran has built in? Does it have a web inteface where you can see active calls, registrations, calls logs, etc? What other options besides Grandstream and Adtran are out there for multi line FXS gateways? I have heard good things about Edgewater. There are about a million no names FXS gateways out there it seems.

Broadworks R17Sp4 to R20 upgrade
by ksuriyaarachchi＠alteva.com March 15, 2015

March 15, 2015

Has anyone upgraded to Broadworks R17sp4 to R20 without any issues? According to the release notes most of the new features in R20 are deactivated by default. However typically every major release is followed by a unimaginable number of patches.

Is anyone sharing RFC 6076 SIP End-to-End Performance Metrics e.g. Session Establishment Ratio
by richard＠teraquant.com March 11, 2015

March 11, 2015

as i understand it, these very specific definitions, for example Answer Seizes Ratio ASR] in SIP terms i.e. Session Establishment Ratio & were produced by the IETF to standardize on measuring performance between carriers . I was wondering if anyone was using them internally and also with any of your interconnect partners? Another example would be Session Defects Ratio (SDR) is the percentage of call attempts receiving the following responses, in relation to total call attempts or INVITES: o 500 Server Internal Error o 503 Service Unavailable o 504 Server Timeout Or do you just measure 503?s?

Why you should present at SIPNOC
by lindsey＠e-c-group.com March 6, 2015

March 6, 2015

You guys do a LOT of research on here. You're constantly making your network better. The science/academic community is mostly done doing the easy 90% of VoIP innovation. Now we in the industry have to make it really work. What you learn in your network could make the WORLD better. SIPNOC and VoiceOps are the leading outlets for industry-proven and leading-edge research into real-time, interactive, multiparty communication. All you have to do is make a 15-minute PowerPoint about the problems you've seen, and how you've solved them. Other folks will learn, and you'll help push the industry forward. -- Russ Penar -- you could tell us what you learn testing this TCP registration optimization stuff. -- Keith LeClaire -- You could tell us how to responsibly report telecom fraud, and how it OUGHT to be done. -- Fred Posner -- You could tell us why we should be organizing ourselves into The Great North American ENUM. -- Colton Conor, Paul Timmins, Jared Geiger -- You guys could tell us about your experiences getting G.722 end-to-end through the various carrier options. -- Shaun Gill -- You could tell us what's on the Fraud-detection landscape. What works, what doesn't work, what the costs and limitations are of the different approaches. -- As for you other frequent contributors -- like Shripal Daphtary, Ryan Delgrosso, Alex Balashov, Jay Hennigan, Carlos Alvarez -- I know you've got some real triumphs and challenges from the past few years that you could bring us in on. Presenting at SIPNOC is good for your employer: -- You show your company is leading the field. -- You pay nothing to get into SIPNOC. -- And you yourself hear the state-of-the-art from other industry practitioners. -- You make networking connections that help grow your business.

FCC 499A and traffic studies
by nathana＠fsr.com March 6, 2015

March 6, 2015

'lo, Not sure if this is the right forum to talk about this (regulatory policy/rules, and U.S. centric ones to boot); if not, feel free to ignore. We're doing interconnected VoIP, and for past 499A filings we have just elected to use the statutory "safe harbor" inter/intrastate traffic ratio of 64.9%/35.1% for providers like us. This time around, we are trying our hands at some traffic studies, but it's unclear to me exactly what traffic we are supposed to be capturing in these. Do they want all traffic captured, or just traffic that could be conceivably billed to the customer (regardless of whether it actually is or not; we don't do postpaid minutes billing) and thus is potentially revenue-generating? That is to say, should a comprehensive traffic study capture all minutes, or just call termination minutes? And should call termination minutes that are the result of a customer of ours dialing a toll-free number be counted, since the callee would be picking up the tab on those? (Seems to me that revenues for interstate toll-free and collect calls should be reported by the callee's phone company, and revenues for interstate toll calls reported by the caller's phone company. Thus why I wonder whether our traffic study should ignore outbound toll-free minutes and also ignore all inbound minutes UNLESS the inbound call is to a toll-free DID.) Also, what technically constitutes an interstate call? Can that be determined solely based on the area code of the caller and callee, or can (or should) the actual call path be the deciding factor? How do nomadic (e.g., mobile/wireless) providers handle this? If someone with a mobile that has a New York number is physically in Seattle with that phone, and the phone is connected to a cell in Seattle, and (s)he calls a Seattle landline, is that an interstate call or an intrastate call? Thanks, -- Nathan Anderson First Step Internet, LLC nathana at fsr.com

Broadworks URL Dialing
by James.Hird＠cdk.com March 2, 2015

March 2, 2015

Greetings All, I am attempting to fix a condition with camped calls where a camped calling party never transfers to a now idle user unless there is a DID assigned as well as extension. We have found that once the URL Dialing policy is added to the routing profile that the network server lookup succeeds. We have never enabled the URL Dialing policy on the Network Server routing profile except for testing in the lab. Can any of the BroadWorks users out there comment on the impact of enabling URL Dialing across the BroadWorks platform?
