TDM SS7 <-> SIP with Cisco, Dialogic IMG1010 and/or AudioCodes Mediant gear...
by pchilds＠internode.com.au Aug. 19, 2009

Gday folks. I'm looking at some TDM SS7 to SIP options to interconnect our BroadSoft/ACME SBC platform to a more traditional SS7/TDM telco. We have been checking out a PGW based solution, and also some of the more 'gateway' type devices (such as those from Dialogic and/or AudioCodes...) Whilst this may seem a very 'open ended' question has anyone had any hands on dealing with these solutions that can highlight any potential concerns and/or positive experiences? Cheers, Peter

Billing platforms
by voiceops＠treharne.me.uk Aug. 19, 2009

Aug. 19, 2009

Hi folks, What billing/rating/mediation systems are people using, out of interest? I think I've managed to hit both ends of the scale so far - I've worked with home-grown systems with lots of python scripts and very tight integration with existing internally developed CRM....and on the other end of the scale I've worked with Oracle Portal (snappily renamed post-acquisition as Oracle Billing and Revenue Management System). Cheers, Aled.

VNXX

What does the FCC and/or intercarrier compensation reform crowd mean, exactly, when they say "Virtual NXX?" Is that some class of clever remote call forwarding schemes from a CO where the call between it and your rate center is rated LD by the ILEC, but which some call forwarding product manages to get around or mitigate somehow? Or does it refer to carriers picking up inbound calls at the LATA supertandems by carriers from rate centers in which they don't have direct end-office trunking and whose number blocks are not homed to the tandems (any tandems) to which the carrier is connected? This was rather common during the dialup boom and often skirted the 'DS1-of-consistent-usage = DEOT needed' requirement in most form ICAs, as I understand it. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (678) 237-1775

Hi, Is anyone up for an BoF session at Connections? I'm probably not going, but whoever does go might want to hook up. Any other conferences coming up for potential BoFs? While we're on the whole F2F thing... If you're near Portland, OR, give me a shout. See ya, David

Lower executive expectations for VOIP?
by hiersd＠gmail.com Aug. 14, 2009

Aug. 14, 2009

Hi, There's a thread on nanog about some gomer at idiot.net breaking a big hunk of routing because they didn't filter BGP properly. It got me thinking about running phones over the internet... In my experience, when we replace a TDM phone with a VOIP phone the expectations for reliability and quality are unchanged at the highest level. In other words, as long as its two lumps of noisy plastic connected by a stretchy cord thingy, the CxO's expects the classic (mythical?) five-nines of the TDM world. Do you get cut any slack just because its a VOIP phone, and VOIP is totally cool? Thanks, David

Cable cut affecting Bangladesh

Dhaka, Aug 14 (bdnews24.com)?International connectivity to Bangladesh returned Friday evening after a 16-hour disruption as the country's submarine cable link was restored in Cox's Bazar, a top official said. "We heard that the link was restored around 6.30pm," said managing director of Bangladesh Submarine Cable Company Ltd Monwar Hossain. Internet services countrywide were severely disrupted by an overnight break in the link connecting Bangladesh to submarine cable SEA-ME-WE-4. I'm not seeing my Bangladesh routes restored yet, so the cable fix annoucement might be a bit premature, anyone else having issues with Bang traffic today yet? Colin

Single fan loss cause netra meltdown?
by hiersd＠gmail.com Aug. 13, 2009

Aug. 13, 2009

Have you ever run a netra 240 or 440 with one fan out of service? I saw a notice today that indicates that the thing will eventually overheat if only one fan dies. The notice did not mention any specifics about the ambient temp or airflow conditions. If this were a common occurrence, you'd think that it would have gotten more press by now. Thanks, David

Geographic redundancy

Aug. 13, 2009

What with the NANOG list being flooded with news about the flood (http://www.datacenterknowledge.com/archives/2009/08/07/water-main-break-at-…) I figured it'd be a good time to ask.... Has anyone really solved the whole config sync and operational failover issues to provide full geographic redundancy for a hosted voip network? Failing over TDM DS3s, SS7, IP, SIP, voicemail, IVR programming, etc, such that there is no user-observable indication that failover occured between two calls is the big goal.

BellSouth vs. AT&T stance on multi-tandem access.
by abalashov＠evaristesys.com Aug. 13, 2009

Aug. 13, 2009

Bellsouth was thought by many to be the most friendly to CLECs of all the divestiture RBOCs. Traditionally, in its 9-state operating area it was possible to do multi-tandem access; that is, you didn't have to have trunks to all the intra-LATA sector tandems in order to terminate to an end-office in that sector, as long as you had transient groups to the LATA access tandems. I have heard that the AT&T crowd does not take kindly to that and that this option doesn't exist in ex-SBC territories, or anywhere else. Can anyone confirm? Does anyone have any information on how that's being approached since the merger for new ICAs and/or if they're taking the opportunity to demolish that when Bellsouth-era ICAs are updated and/or renegotiated? Are folks that went up in Bellsouth days grandfathered on MTA? -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (678) 237-1775
