ADT Alarms Special Dialing?
by ajp26＠buffalo.edu Aug. 10, 2015

Aug. 10, 2015

All, I appreciate the insight into this with regard to alarms, especially that they'd trip up T.38, which will probably save me some time in the future. So far so good on alarms and credit card machines, but I'd run into some older CPE type Cisco VG that would mangle and eat modem calls no matter what we did with it. Is there a compendium of information anywhere regarding devices, signaling, and compatibility with CPE? One of our alarm monitoring companies just said that many of their older (FBI type) panels don't work via VoIP in their experience, but other than previously mentioned sensitivity to DTMF it should be possible. Liability and service performance aside, just speaking technically. Also, regarding Sandy and FiOS customers - it was quite a hot topic for a while that the flooding had absolutely trashed the copper plant in a number of areas. Leaded cables with cracked jacket, or enclosures with long-failed positive pressure had allowed water in and ruined the copper. While that's not your run of the mill power or service outage, I'm not entirely certain you can count on a wireline provider to provide longevity of CO battery over time, or even that you're not connected through some span/regen that is independently powered. It certainly helps piece of mind to move the failure "somewhere else" than where you happen to be, but I can't believe it would be as granite-tough reliable as commonly thought.

Suspect NPANXX question
by ryandelgrosso＠gmail.com Aug. 4, 2015

Aug. 4, 2015

All, We have seen a Caribbean NPANXX (1-268-762) advertised to us from a US tier 1 vendor. It has drawn a large amount of fraudulent traffic. We first saw this prefix pop up in this vendors rate decks in April. Going back to the start of the year I cannot find it in any revision of the LERG though, and no other vendor I have offers routes/pricing to this prefix. Does anybody know whats going on here? Shouldn't any zone 1 prefix exist in the LERG months prior to going live, or at the very least within some reasonable time after showing up for live traffic? Does this smell like highjacking to anyone else? All our vendor will tell is they are getting the route from another T1 vendor, but in my 20+ connected peers I cannot find another occurrence. Any help or guidance is much appreciated. Feel free to reply on or off list. -Ryan

AT&T Cellular - DTMF
by Adam.Vocks＠cticomputers.com July 15, 2015

July 15, 2015

Finally Solved! I want to thank everyone who help with advice and/or contacts on this problem. Here is an e-mail from AT&T about this problem. Raghu and I have been working on this today - and we found that there almost certainly exists a 'bug' in the EVC/Nortel MSC (VSE MSC) causing this problem. This issue is being caused by any far end switch that responds to an incoming call with the optional ISUP_CPG (Call Progress) message that does not have the optional BCI parm included (Backwards Call Indicators). If the EVC MSC routes a call to a PSTN trunk group and sends an ISUP IAM to far end, far end sends ACM (Address Complete) and if they also send an ISUP_CPG that does not contain the BCI parm - this causes the MSC to reject any DTMF tone requests from the originating callers. This exact same issue was found in our MSC during a FFA (First Field Application) trial of the previous version of MSC software (uCore5) back in late 2013. We believe that our newest MSC software version (uCore15A) might be missing this bug fix and causing this problem - AGAIN. I have a HIGH PRIORITY case opened up with the MSC vendor that I will pursue with great diligence. SO - for now - the only way to fix this is to change the routing to not use this TYVLILXC50T02A1B trunk group. I will have more info on when we can expect a fix from the vendor - but best case scenario for that would be several WEEKS. I know this is NOT good news - BUT it is all I can offer up at this time. Thanks - We had them route around the problem switch and our problem went away. We're using a Sangoma NSG SS7 gateway. Thanks again everyone! Adam From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Adam Vocks Sent: Wednesday, June 24, 2015 11:58 AM To: voiceops at voiceops.org Subject: [VoiceOps] AT&T Cellular - DTMF I've got an odd problem that someone might be able to point me in the right direction to get some help. AT&T cellular customer calls a number destined to our LRN. Customer presses a digit on the phone, no DTMF audio ever comes across the trunk. If that same customer calls a number with the same npa/nxx not destined for our LRN, DTMF audio comes across the trunk. These calls are coming to us via SS7 trunks and the ILEC that these calls transit through has verified that both calls come in on the same trunks, one has DTMF audio, one does not. This problem started on Thursday morning. Prior to Thursday morning, AT&T cellular calls were arriving to us via our FGD Tandem connection, now they are arriving via the local rate center switch. I've talked to AT&T and attempted to put in a ticket on the DS3 that enters the ILEC, but they refused to do that because they said the DTMF would be audio and they would just pass it through. Anyone have advice? AT&T (low level tech) states that the DTMF tones are generated at the phone and are in the audio stream the entire way. Does anyone know if AT&T uses some sort out of band dtmf signaling? Thanks! Adam Vocks CTI Fiber

Software SBC solution recommendations
by ryandelgrosso＠gmail.com July 4, 2015

July 4, 2015

So I'm working on a bit of a niche project in need of a virtualizable software SBC and while I am aware of many of the open source solutions out there I'm sure there are facets of the various options that those who live with them every day can share that will influence direction. I need this soluton to do: registration caching (but pass reg back to softswitch), nat traversal/media proxy, basic topology hiding, blacklisting, some kind of dynamic routing (ENUM is preferred). No need for fancy multi realm setup, simple inside/outside is fine. I am presently looking at: * Kamailio + some kind of media proxy (does much of the signaling but is not a B2BUA) * Freeswitch (doesnt seem to do the reg cache / pass back) * SEMS (reg caching only introduced last month. * Various combinations of the above (though most of these feel kludgy) Im not precluding commercial solutions or hybrid solutions but the usual suspects (Acme, Meta, Sonus, etc) are off the table here due to either the cost or the software/virtualization requirements. Thanks in advance, -Ryan

Hello All ? I would like to ask how heavily each of us (or our customers) depend on DIA or other non-QoS transport to handle signaling and media on trunking (carrier-to-carrier carrier-to-operator) side of networks. I created the following survey to preserve anonymity of all answering: https://www.surveymonkey.com/s/SKQPQZP I will review the results in few days. Let me know if you would like me to share and Thanks in advance for participating. Thank you, Slava Kosoy
