VoIP (SIP) to VoATM conversion
by brent＠overthewire.com.au Dec. 10, 2009

Dec. 10, 2009

Hi all, Hoping to tap the collective minds here. I am wondering how to best convert voice traffic from VoATM/VoDSL to VoIP (SIP in particular). Here in Australia, a lot of competitive carriers deliver ISDN (up to E1) over SHDSL tails with an IAD of some description (eg Verilink) on the end. We have access to SHDSL tails, but of course with IP overhead we cannot squeeze 30 channels down a 2M/2M circuit if we run G711. Does anyone have any idea on how best to scale a solution whereby we can remove the IP overhead but still use our softswitches (seems to me that a lot of the competitive carriers here are using ATM directly plugged into their older switches). How are others doing this and making it scale ?

OT: Payment bureau
by abalashov＠evaristesys.com Dec. 1, 2009

Greetings, I'm not sure if this is within the purview of the list or not, but I would like to get everyone's thoughts on the creation of something like a "credit bureau" specific to our industry. I don't think we currently have anything like that in the VoIP cottage industry, unless I am mistaken. Simply put, we should have a way of anonymously rating customers' payment history and noting any especially egregious disputes. Access should be restricted only to verified companies legitimately engaged in VoIP-related trade. My interest in this is from a consulting and professional services angle, since that's what Evariste Systems does. However, I do not see why this could not also accommodate payment information from the ITSP and small carrier world. There are lots of potential problems, of course: 1) Some customers would consider disclosure of any transactional information a violation of standing NDAs; 2) The possibility of clutter from small/irrelevant transactions, like $5 prepayments for O/T or calling cards; 3) Some need for moderation and standards enforcement; there is a very real possibility of abuse by members by leveraging such a tool in frivolous business disputes, or business disputes in which their hands are not clean any more than the customer's; example: I could fail to deliver to a customer what I promised, and then report his refusal to pay as a financial misdeed; 4) Large deals and transactions often already go through credit checks with real credit bureaus and various ratings firms. Nevertheless, I think there would be a lot of value as well. And while there is the possibility that the existence of such a tool could be used to intimidate/threaten customers in business disputes, the value of catching fraudsters who go around from VoIP company to VoIP company ripping each one off and disappearing into a hole might outweigh that. My father does, among other things, some freelance translation. In that industry, there's a web site called: http://www.paymentpractices.net/ It is upon seeing this that I wondered why we do not have something like that in our world.

Hi All: Have you seen issues with Cisco Catalyst Switch in the IBM Blade Center that causes all the other Cards in the Blade Center to be partially responsive.

Probably OT Ports for Broadsoft
by mylists＠battleop.com Nov. 23, 2009

Nov. 23, 2009

Please forgive me if this is off topic but I am striking out on the Google lottery. Can someone point me to where I could find what ports a phone connected to a Broadsoft switch would use? I am guessing 5060-5080 and 10000-20000 but not having worked with a Broadsoft switch I don't know for sure. Richey

Cisco SBC - feedback ?
by benc＠brennanit.com.au Nov. 23, 2009

Nov. 23, 2009

Greeting, I recently came across Cisco's offering for a SBC -> The 'ACE20-SBC-K9' http://www.cisco.com/en/US/docs/routers/7600/install_config/sbc_config_guid… I was Curious who out there uses this and what their thoughts on the product was or any feedback for that matter on it. Up until recently we were heading down the Acme Packet path, however most of our Current infrastructure is Cisco, so it kinda of makes sense to take a serious look at this. Cheers.

Yate B2BUA as media gateway controller
by abalashov＠evaristesys.com Nov. 17, 2009

Nov. 17, 2009

The release notes of Yate 2.1 (released 02 November 2009) contain what struck me initially as a somewhat extraordinary claim - that its new MTP2/MTP3 support combined with MGCP can be used as a drop-in replacement for a Cisco PGW2200 to drive Cisco AS5xxx series gateways. At first glance, this does appear to be possible. Does anyone have any experience or first-hand perspective on this? Of course, the media gateway control protocol is limited to MGCP - there is no H.248/MEGACO support.
