Anyone aware of a voice fraud mailing list or listing service? Something of a repository of new attack vectors and remediations or something . . . just thinking it would be cool to see what new attacks people are running into. If not, any thoughts on something like this? Rob

IXC/LD No audio or delayed audio
by steve.starr＠daystarrfiber.net April 23, 2015

April 23, 2015

A growing number of IXC/LD calls inbound into us have either no audio or delayed audio. We are attempting to narrow down the common carrier, but this is a difficult task. We have IXC trunks with multiple providers. So far it seems to be mostly our ATT trunks and Neutral Tandem trunks. ATT being TDM and Neutral Tandem being VoIP. This leads me to believe it is an IXC carrier causing the trouble and not circuit trouble. Also, it is just inbound. When our customer returns the call it is fine. If the person calls our customers tollfree it completes fine. Is anyone else experiencing the trouble? Does anyone have any contacts at ATT that might be able to assist?

Broadsoft SCA
by colton.conor＠gmail.com April 23, 2015

April 23, 2015

We are using Broadsoft with Polycom VVX phones. We have noticed when we have a seat that has a primarily phone and then a secondary Shared Call Appearance phone, there are certain tasks on the primary phone that we can not do or see on the secondary SCA phone. I am trying to determine if these are Broadsoft/Polycom limitations, or if we have something configured wrong. For example. 1. If a call come in, both phones ring. If you pick the call up on the primary phone, and then place the caller on hold, the secondary SCA phone's line will flash. You can hit the flashing line, and resume the call on the secondary SCA phone. However, we can't do the opposite. If a call come in, and the call is picked up on the secondary SCA phone, and you place the caller on hold, you see nothing on the primary phone's line. The line does not flash, and there seems to be no apparent way to resume the call. 2. BLF's show up on the primary phone's screen, but not on the secondary SCA's screen. Is that normal? I am not to familiar with provisioning, but I know these phones are provisioned using Broadsoft DMS. Does Broadsoft DMS have a different template for a primary phone vs a SCA phone? If so I am thinking something is missing on the SCA template that is on the primary.

Which low cost 24 and 48 port gigabit PoE switches are most VoIP providers deploying to small business customers? I have heard many are using the Cisco Small Business switches, but some of these are now EOL.

Easy ways to measure PDD
by beckman＠angryox.com April 22, 2015

April 22, 2015

So after a recent discussion about how to quickly diagnose SIP calls from packets (tcpdump + sngrep for the win!), I'm now wondering if there is a tool I don't know about that would be able to parse the same .pcap file that contains all of my port 5060 traffic and output the PDD time for each call found within. Bonus points if I can specify a time/date range. I don't want to manage yet another server or metrics repository in order to hold all of this call data, so some of the larger (and pricier) tools mentioned before are out for me. I've contacted the author of sngrep and though the packet capture code is already there, he reasonably doesn't want to turn sngrep into sipawk or sipsed.

FW: Easy ways to measure PDD
by richard＠teraquant.com April 20, 2015

Do you have an SBC or switch that already measures this and outputs it with the CDR? Do you want to report on all PDD long-term? Or just one or two specific calls?

Technically, 1-to-5 and 2-to-4 is correct but either should work. The other way swaps tip and ring which won't make a difference in this or most applications. Odd-numbered pins are tip, even are ring. Mostly white conductors with color stripes should go the odd pins (tip). -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV

Toll Free as Outbound CLID
by shripald＠gmail.com April 20, 2015

April 20, 2015

Hello everyone, i'm just wondering if there is a legal/regulatory issue with having a TFN as the outbound CLID for a customer on our hosted platform(s). On the broadworks, the system won't even allow for it. However, on our M6, it doesn't really care. thanks Shri

nonprofits

This may seem like an odd request but I am looking for a provider that has a focus on the nonprofit segment. I am looking for nonprofits that can use a donation of free consulting services to onboard the origination to Office 365 and then the provider can carry the Lync voice traffic. The origination would also receive free Office 365 licensing. Cheers Ryan
