We've had the same issue arise during ports, primarily from T-Mobile and AT&T Wireless. The below link will take you to the ATIS website that has two contact documents for various carrier NOC's (Company Specific Contact Directory and LNP Contact Directory). The contact directory is very extensive and includes LNP Trouble Reporting. You'll need to register with ATIS. Hope this helps. http://www.atis.org/niif/cscdlnp.asp Nick Reifschneider 360networks/VoIP360 Product Director, VoIP Services 370 Interlocken Blvd., Suite 600 Broomfield, CO 80021 Office: 303-854-5040 Cell: 303-324-4092 Fax: 877-349-2949 SIP Origination, Termination and Local Access in the Western US From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Frank Bulk - iName.com Sent: Tuesday, December 01, 2009 1:28 PM To: 'Scott Berkman'; voiceops at voiceops.org Subject: Re: [VoiceOps] Contacting Carriers and CLECs (Specifically T-Mobiletoday) We've found that if we don't know someone from the inside, or have a partner in the inside, is to get a T-Mobile customer to open up a trouble. It takes a day or two, but they do get resolved. Frank From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Scott Berkman Sent: Tuesday, December 01, 2009 1:42 PM To: voiceops at voiceops.org Subject: [VoiceOps] Contacting Carriers and CLECs (Specifically T-Mobile today) Does anyone know of a centralized list or standard method of reaching other CLECs and Carriers, specifically Cell Carriers? Something similar to Puck's NOC list (http://puck.nether.net/netops/) is what I am thinking of. We are having some routing issues to certain numbers we own from T-Mobile and are having issues reaching the right type of support staff, especially since you can't even get their regular support without an account.
