by keith.wood2000＠gmail.com Feb. 27, 2010

Feb. 27, 2010

Hi I would like to get in touch with the tier 1 carriers such as AT&T, Verizon, Level 3 or any CLECs in US and Telus/Roger-AT&T in Canada about a potential project cooperation on international traffic peering/interconnecting. I am wondering if anyone on this list may belong to one of those organizations or know any senior management in those organizations? I would greatly appreciate any referral. I am looking to talk to the person responsible for wholesales termination/origination. Thanks alot for your kind help. Keith

We were approached by a company looking to do 1.5m minutes/mo into Malaysia and Singapore. We're weak on this. Anyone here have a local presence and want the contact info? Target rate is under 4 cents (USD). -- Carlos Alvarez TelEvolve 602-889-3003 Advanced phone services simplified

Certifications for Carrier VoIP
by lindsey＠e-c-group.com Feb. 24, 2010

Feb. 24, 2010

Is anyone aware of a certification program for Carrier VoIP? I know Cisco has some things -- but they're focused on Cisco-flavored VoIP, not the multivendor stuff we do here (Metaswitch / BroadWorks / Acme Packet / Cisco / Taqua / Sonus / Nortel / Polycom / Linksys / Aastra / etc.). Acme Packet and BroadSoft both have some certs for their own products, but knowing a lot of about either of those isn't enough to build and run a whole network. mark r lindsey at e-c-group.com http://e-c-group.com/lindsey +1.229.316.0013

It's been a while since I've looked at the call control interface in any detail, but I think the application itself maintained a single connection and communicated over that connection.

BW RADIUS CDR interface
by jnesheim＠cytek.biz Feb. 22, 2010

Feb. 22, 2010

I think it depends what you're planning on using it for. In my case, I wanted to use it for call traffic analysis (ex. calls volumes to NPAs, gateways, etc) and troubleshooting tools for our repair departments. I had developed a perl module for FreeRadius that would store the CDRs into a reporting and troubleshooting database which worked out fairly well. However, the licensing model that Broadsoft uses for the Radius interface isn't very "efficient" and has been a major problem for our deployment. It seems Broadsoft only anticipates customers using the Radius interface for enhanced call logging and billing and prices it around that which makes it an expensive feature to use solely for network analysis. Other than the licensing issues, the interface works fairly well. It could use some better documentation on what the VSAs are, but most of that can be reverse engineered from the CSV accounting files since the column sequences line up with the VSA numbers. -- Jason Nesheim ----- Original Message ----- From: "David Hiers" <hiersd at gmail.com> To: VoiceOps at voiceops.org Sent: Monday, February 22, 2010 6:30:04 AM Subject: [VoiceOps] BW RADIUS CDR interface All, A quick question for the brain trust: If you use the BW RADIUS CDR interface, are you happy with it?

Utility for Splitting MGCP Calls from large packetcaptures?
by jrandall＠comwave.net Feb. 22, 2010

Feb. 22, 2010

I know using Wireshark it seems to print a GUI latter for MGCP calls however when trying to apply a filter for the packets based on the "VoIP Calls" section for some reason my experience has been that it doesn't work (haven't tried on any newer releases of Wireshark in a while). You'll likely need to write your own using libpcap or BASH/Perl scripting around tethereal. The main challenge is that the endpoint IDs in an MGCP messages are only sent in the MGCP requests but not on the response which means you need to find all the TIDs/IPs/etc belonging to the endpoint transactions you're interested in and then find all the associated response packets based on TIDs and IPs.
