Lync, VPN and DNS?
by rvandolson＠esri.com Feb. 3, 2015

Feb. 3, 2015

We have a corporate Lync environment with a large # of users hitting it via their VPN tunnels. We've set up routing on the VPN client side to allow VOIP traffic to be routed over the public network rather than through the tunnel -- if we can just get the DNS lookups to return the public IP's instead of the internal IP's. We run BIND and I'm struggling to see a solution short of creating a special view or separate BIND server just for VPN clients in which I need to create many zone files to override the relevant Lync DNS records (one zone per record since unfortunately all of our Lync-related records live within our primary domain). Seems ugly and error prone. Maybe BIND's RPZ could help? Or maybe there's some simpler solution I'm missing. We also have F5 w/ GTM -- maybe some magic could be done there. Any thoughts/advice? Ray

Shaun: I have used the TransNexus solution for a long time. Jay Cox Mobile 314 910 7242 From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Shaun Gill Sent: Wednesday, January 28, 2015 2:37 AM To: voiceops at voiceops.org Subject: [VoiceOps] Fraud Management Hi Guys, Trying to get a feel for what fraud systems are out there for VoIP service providers; primarily using terrestrial mediums (such as metroE; diginet) with clients interconnecting via IP PBXs, voice gateways and IP phones. We have had fraud to international premium destinations which we are restricting based on calling profiles and originating source IPs; but neither is truly scalable. Subsequently we are looking for alternatives. Regards, Shaun

Jan. 29, 2015

Hi list, I need to be able to terminate toll-free calls to the mentioned countries via SIP. Any carriers in these countries here or otherwise someone who can provide TF termination to these countries? It doesn't have to be toll-free for me. Willing to pay per minute. Just need to be able to reach TF numbers in these countries. Thanks! Markus

Impulse hits out of Sprint PCS to WI
by jra＠baylink.com Jan. 26, 2015

Jan. 26, 2015

On late-afternoon calls to 2 Wisconsin landline numbers yesterday, I heard a large number of impulse hits akin to DS-1 clock slip. The calls were from 727-647 homed in St Pete FL to 715-258 and 920-722. Anyone got a channel to clear a problem report like that? I tweeted it, but I think Sprintcare's odds of themselves knowing where to send it are 50/50. Calls were at 1544 and 1546 EST and again at 1720. Cheers, -- jra -- Jay R.

Hi All: We are being told by Level3 that if a Canadian DID calls a Canacdian TF number, they cannot guarantee call complete and its best effort. Anyone else run into something similar?
