Call forwarding issue
by Rod.Dossouvi.CTR＠dot.gov Aug. 20, 2009

Aug. 20, 2009

user is trying to have calls forwarded to her cell phone. When enters: 9-xxx-xxxx, local callers get forwarded fine, but long distance callers get an error. Alternatively, when user enters: 9-1-615-xxx-xxxx, long distance callers can now get through, but local callers get the same error. Any input? Thank you.

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

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

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
