Port out info for Charter Fiberlink - MA
by matthew＠corp.crocker.com May 25, 2011

May 25, 2011

Does anyone have the port out information for Charter Fiberlink -MA? I have a couple of LNP requests to get into them and their customer service reps are clueless to the process. URL for their CSR interface or TN to their LNP department would be great. Thanks -Matt -- Matthew S. Crocker President Crocker Communications, Inc.

I'm not sure what your requirements are but, we recently blocked all non-ARIN IP space from reaching our registrars. We had something similar happen and this has?essentially?eliminated the fraudulent calls we saw.

Low-volume international VoIP carrier
by carlos＠televolve.com May 19, 2011

May 19, 2011

We do a very small amount of international traffic, but for the customers who need it, we have to provide it. Right now we mostly use Simple Signal for that traffic, but we have both random and recurring issues (like right now we can't call Ireland mobiles). I'd like to add a second carrier, or make a switch. Any suggestions on a good international carrier with low minimums? -- Carlos Alvarez TelEvolve 602-889-3003

Wireshark Voip Calls Filter with no RTP
by kleclaire＠mywdt.com May 16, 2011

May 16, 2011

Hello All, I've recently upgraded to Wireshark 1.4.6 for MacOSX and have found that now when you do a Telephony->Voip Calls on a capture and then use that to prepare a filter, the filter no longer includes the RTP packets. It seems that the filter has changed from being packer # based filter to a filter based on the SIP Call-ID field and thus no RTP is filtered here. Is there a way to change this or have it got back to filtering the RTP as well? Thanks, Keith

Sonus NBS5200
by anorexicpoodle＠gmail.com May 9, 2011

May 9, 2011

Hey all, I recently noticed Sonus is now marketing a stand-alone SBC called the NBS5200, which seems to be all the SBC functionality from their NBS9000 minus the TDM gateway. Has anyone out there had a chance to actually use one in a lab or is currently using one in production? If so how do they stack up against Acme? Any opinions on how they perform in an access side role coping with huge volumes of far-end nat traversal? Ive done the first part of the sales mating dance with them, but am interested in getting some real-world opinions if anyone can offer some. Thanks in advance -Ryan
