VoiceOps Digest, Vol 24, Issue 3
by jaredball1＠gmail.com June 3, 2011

June 3, 2011

I've seen ghost ringing with broadsoft's call transfer recall feature. The scenario was that an operator transferred calls to a hunt group and when they didn't answer in time the call was recalled to the operator. The phones continued to ring even after the call was recalled. This was with broadsoft R14 and a patch to the application server resolved the issue.

Broadworks hunt group CNAME manipulation
by nelsonh＠socket.net June 3, 2011

June 3, 2011

Hello, We have a few hunt groups built out in BroadWorks and have noticed that the hunt group name is prepended to the caller name when an inbound call to the hunt group is sent to one of its members. This could be a very useful feature, but our current hunt group customers don't want this and the only setting I've found for it in Broadworks disables it globally. I've looked for options to rewrite the caller name part of the display field, either on our SBC or the TA900 CPE, but neither seems to support stripping off the first part of the display name and leaving the rest. Has anyone else already dealt with this? If so, what solution did you end up with? -- Nelson Hicks DNS and Web Administrator SOCKET (573) 817-0000 dns at socket.net 1-800-SOCKET-3 www.socket.net

OpenSIPS/Kamailio serving far end nat traversal
by sipphoneguy＠gmail.com May 26, 2011

May 26, 2011

Has anyone successfully deployed OpenSIPS/Kamailio to do far end nat traversal for endpoints? I am looking to deploy something similar to either of these products to handle our IP endpoints at the edge of our network for work at home agents and dont want to spend big money on an SBC to do it. Thanks for your input and help in advance. -SIPguy

Inbound DID pricing model
by compuwizz＠gmail.com May 26, 2011

May 26, 2011

So now that Verizon decided to change their pricing from Unlimited Channels/Unlimited Minutes inbound DID pricing to being charged per minute for inbound calls, is there another carrier that offers the old model pricing? I know most carriers do either 1) Unlimited channels and per minute pricing or 2) Per channel pricing / Unlimited minutes. This topic is probably in a grey area for this list so I apologize if I offend anyone. ~Jared

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
