Phone Numbers with Calling Restrictions
by tim.donahue＠gmail.com Jan. 22, 2014

Jan. 22, 2014

Hi all, I am wondering if anyone has ever heard of DIDs that are restricted so that only intra-lata or local calls are allowed to complete. We have never come across this before, but we are being told that one of our DIDs falls into a block with these restrictions in New York. Any pointers to information about this would be appreciated. Thank you, Tim

Strange inbound Calls

We've been seeing these as well. About one call a day. Sometimes as many has 3 or 4.

If so, what do they hear? If not and it's an IVR, if you call and say nothing does the call drop in 60 seconds? City and state are not uncommon for CNAM. Many CNAM providers will put the city and state of the rate center for the NPA-NXX if caller name isn't available. -- 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 _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops

(cross post) VoIP heat charts...

Sort of off-topic, but sort of on. Looking for something that I can plop in some CDRs and paint a nice pretty heat chart picture of where calls are going. Anyone ever undertaken a similar task, if so, would you have a software you'd recommend.

I have used Google's Geo Map and Intensity Map (along with other charts etc.) for internal dashboards and it is really easy to use. I use it to visualize values which make sense in the context I am looking for whether it be a representation of call volume, minutes, spend etc. It probably isn't something you want to display publically but as an internal tool it is simple and effective. Obviously this is an external service but you are sending data without context to it so use your best judgment on whether it is appropriate for you to use within your IP and security policies.

PacWest termination issues in So Cal

We're seeing strange problems with calls inbound to our customers, mostly NPA 805, through PacWest. They claim it's just us.

Uverse - CGN?
by jra＠baylink.com Jan. 6, 2014

Jan. 6, 2014

Does AT&T Uverse (specifically Cleveland OH) use CGN? If so, how would that affect an off-site IP phone extension to a PBX? I would assume you might need to VPN to the main LAN to avoid half-audio problems? Cheers, -- jra -- Jay R.

EVRC IPR Licensing
by srao＠ctigroup.com Jan. 6, 2014

Jan. 6, 2014

I have a client who requires the use of the EVRC (Enhanced Variable Rate) CODEC (wireless). Based on some online research I can see that there are a host of IPR owners for this CODEC. Does anybody have any experience licensing or acquiring EVRC media ports? Thanks in advance for your assistance. Best Regards, Sid Rao

Spoofed Traffic
by jared＠compuwizz.net Dec. 17, 2013

Dec. 17, 2013

One of our customers is reporting that their ANI is being used to make calls. I've verified that the traffic isn't traversing our network, but I'm not sure of where to look next. The customer doesn't necessarily want to know who is making the calls, but wants them to stop. I know I can contact Verizon, who owns the number, but since the calls aren't being originated from us or our customer, I'm not sure how they can help. Does anyone have ideas of how to go about blocking this since we aren't the LEC owner of the DID? ~Jared
