Verizon

Hello, I'm new to this list but, I'd like to know if anyone has a contact number for a Verizon/MCI Metro NOC in MS? We've identified a Verizon/MCI Metro number in MS that's call forwarded to one of our customer's toll free. Our end user is receiving multiple calls from MS residents who are calling the Verizon/MCI Metro number and are mistaking like terminated on our clients toll free. I'd like to speak with a switch tech to undo the forwarding. Any help would be appreciated. Thanks, Rafael Ruiz Hunt Telecom

The peer of my peer is my peer?

The great thing about the vocalized approach is that it maintains the telephony application passed down to us by AT&T. But the tragedy is great, too. We're all working so hard to limit ourselves to the telephony of 1990: -- No video. -- No better-than-g711u audio. -- No distributed presence. -- No simple file transfer (which means you're stuck supporting fax machines). -- No easy conference control (moderation, floor control, remote mute, etc). -- No location conveyance ("Bring me a large pepperoni pizza. Goodbye."). -- No simple authentication. -- No encryption. -- No easy relocation of handsets. Geoff, anorexicpoodle, and Paul are all arguing for a sober approach: "The job of the network is to ensure people can carry on voice conversations, so the network should do anything necessary to ensure this occurs." So we centralize all our control into a few central, core devices that act a lot like the 1ESS of 1965. But we're all using technology designed by an entirely different mindset. All through the VoIP RFCs, you get the idea that the job of the network is to allow endpoints to interconnect however they want. Only by pushing intelligence to the leaf nodes of the network can you have scalable distributed applications. We are selling the services that customers know they want. But please don't pretend that that the network we're building is the final answer for IP-based telecommunications, or even the most interesting realization of VoIP technologies.

Bandwidth.com Wholesale opinions?
by jared＠compuwizz.net July 14, 2010

July 14, 2010

I'm talking with them to start setting up a wholesale sip trunk with them. The rates look great. In the past it seems they were mainly a Level3 reseller. However now that they are a CLEC, have they mixed in other carriers as well? Whats the general opinion of them? I see from today's thread they only are a SIP proxy and don't touch the media so I may have ON-net issues with their customers every now and then. Are there any other complaints or compliments for them? ~Jared Geiger

By the time I had our switch vendor on the phone Friday everything was working fine and I couldn't make it error. May never know but at least now I know how to get the ss7 captures.

ATT Wireless Dropped Calls
by clec＠cygnustel.com July 11, 2010

July 11, 2010

This is a strange issue I just found out about, not sure how long it has been happening. Apparently any ATT Wireless calls that come into our system (an possibly just those that terminate into asterisk via sip(only complaints so far)) are dropped. Our switch is connected to ATT Wireless over ISUP/SS7 trunks and the calls are coming out as SIP. Asterisk gets a SIP INVITE from the switch, then responds with a 100 Trying and a 200 OK, The switch then sends an ACK and then a BYE. The ATT Wireless customer just hears beep beep beep call lost. Any ideas? It doesn't happen 100% of the time, but the vast majority. Also a Wait(1) in asterisk before answering doesn't seem to make any difference? Thanks for any ideas! -Eric

Role of D.C. Agent
by clecny＠gmail.com July 7, 2010

I just learned that a new telecom service provider must have a DC Agent. Can anyone explain why a CLEC must have DC Agent and what is the role of a DC Agent. Any referrals? Thanks much!
