VoSKY Exchange Pro VISIP-EX SIP PBX-to-Skype gateway

August 19, 2008

VoSKY
just announced the VoSKY Exchange Pro VISIP-EX, a SIP-to-Skype gateway product that bridges the Skype network with SIP-based IP-PBXs and SIP gateways. The VoSKY Exchange Pro VISIP-EX enables companies with SIP-enabled PBXs to add Skype trunks for inexpensive calling. This isn't the first SIP-to-Skype gateway, I've written about others here, here, here, and here, however, this is the first "Skype-certified", enterprise-grade PBX-to-Skype gateway for SIP networks.

The new VoSKY Exchange Pro VISIP-EX is based on the company's enterprise-grade Linux platform and connects an IP-PBX to Skype to dramatically reduce telecom costs up to 90% over traditional telco trunks according to VoSKY.

The VoSKY Exchange Pro VISIP-EX integrates with any existing IP-PBX through SIP trunk ports and adds up to 30 lines of Skype.

Free World Dialup (FWD) No Longer Free

August 6, 2008

Saw this news on http://www.freeworlddialup.com/ stating that Free World Dialup, often referred to as FWD is now no longer "free" but now has a $30 annual "fee". Well, at least they get to keep the FWD acronym since both have the letter 'f', but the domain name is no longer accurate.

Anyway, FWD was one of the first free SIP-to-SIP calling services using their SIP registrar (fwd.pulver.com:5060). It seems to me that FWD has had its loyal but small fanbase, but honestly I think it's outlived its usefulness. I can setup a FREE account here on FreeCall.com and not only get SIP-to-SIP calls for free, I can also get free calls to many PSTN destinations around the world!

How much data does fring consume?

August 5, 2008

Ever wonder how much data fring consumes when making a VoIP call or even when idle? Personally, I really like fring which I like to call "the Swiss army knife of mobile VoIP and IM", since it works with Skype, SIP, MSN Messenger, Yahoo! Messenger, Google Talk, ICQ, and AIM.

Well, I found the answer to this question on fring's blog which was posted today.

When idle, fring also consumes an additional 10kb per hour of connectivity to communicate with fring's servers. This is needed to get/push presence and other info.

OpenSIPS Forks OpenSER

August 4, 2008

Came across an announcement that OpenSIPS is forking from the popular open source OpenSER solution. OpenSIPS (Open SIP Server) became active today, with its first release (OpenSIPS 1.4.0). I found it a bit surprising that someone is forking OpenSER, since it's a very powerful SIP routing platform. I recently mentioned how OpenSER can be used to bridge Asterisk with Microsoft Office Communications Server 2007.

The IP-PBX Energy Wars...

August 4, 2008

So today I get a new report from the Tolly Group stating that the ShoreTel Unified Communications system is significantly more energy efficient than the Cisco Unified Communications Manager. ShoreTel apparently topped Cisco in using less energy to drive VoIP communications in specific large, medium and small enterprise-class scenarios.

This energy usage comparison reminded me of Nortel's "The 'Nortel' Tax Relief Plan", which aims to "stop paying the 'Cisco Energy Tax' and save up to 40%". Tony Rybczynski who works for Nortel and writes a TMCNet blog called The HyperConnected Enterprise sparked some controversy with some of his blog posts promoting the fact that Nortel is more efficient than Cisco. He even cites one customer that put a stop order on a $2 million dollar Cisco order once they did the energy efficiency calculations.

Is that what it's come down to?

Level 3 & Packet8 major outage

July 31, 2008

BREAKING!
A source is telling me that Level 3 Communications and Packet 8 are having a system-wide network outage for the last 30 minutes. Level 3 is a huge provider of VoIP termination and I believe Packet8 uses their network for termination. Other VoIP service providers (Vonage?) will also be affected if indeed Level 3 is having an outage. I'm trying to confirm this as I type this.

3CX Free SIP Softphone

July 31, 2008

3CX has announced the release of a totally free new VoIP softphone called 3CX VoIP Phone that allows users to make and receive calls from their computer using SIP-based VoIP providers or SIP-based IP-PBXs. This free SIP softphone client isn't the first "free" softphone on the market. That distinction belongs to Counterpath's popular X-lite SIP softphone. However, I'm glad to see more free SIP softphones on the market.

In fact, I'd like to see free SIP softphone clients for Windows Mobile and the iPhone. Counterpath, had one for the PocketPC but they discontinued it.

VoSKY launches T1/E1 PBX-to-Skype Gateway

July 29, 2008

VoSKY today launched a high-density T1/E1 PBX-to-Skype Gateway. Who needs SIP trunks when you can have 23 or 30 simultaneous Skype trunks?

Though I'd like to see a 100% software-based gateway solution for IP-PBXs, since like Skype, they run on the IP network already. Still for traditional PBXs with T1/E1 interfaces, getting a PBX-to-Skype gateway to migrate away from expensive per minute charges on the traditional PSTN makes a lot of sense.

Astricon, Win $100, and Party Hardy at ITEXPO

July 29, 2008

Came across DIDx (DIDXchange) CEO Suzanne Bowen's blog today, where she mentions that DIDXchange is sponsoring the Code Zone Reception on Tues PM Sept 23 at Astricon and also "giving a lightning talk with some of you on DIDX and IAX2."

She includes a sign up link to http://www.didx.net/astricon2008/, but the link doesn't work.

Anyway, she's offering an interesting survey with the chance to win a $100 gas card or $100 American Airlines voucher.

"Whether you are using IAX2 or SIP or both, please reply to this survey asap. Just copy the Qs and paste them to me on email or on Facebook message with your name, company, if you have a DIDX account ... include that number, cell phone and email for contacting. Each person who uses IAX2, SIP, or a combination AND also DIDX who answers this survey fully with complete contact information to me on Facebook or my regular email will be entered in a drawing for $100 gas card or a $100 American Airlines voucher."

Considering it's $15 per checked bag, and $100 per piece for the 3rd, 4th and 5th checked bags, this $100 voucher won't get you very far if you're a heavy packer.

sipgate vs. T-Mobile Round II

July 28, 2008

Thilo Salmon of sipgate, makers of a SIP-based client that works on the Apple iPhone, wrote me today regarding sipgate vs. T-Mobile Round II, which was soundly won today by sipgate after a German court issued a preliminary injunction against T-Mobile Germany. (See Round I - T-Mobile VoIP Shenanigans - AGAIN!)

Thilo told me, "I thought you might like to learn the we did not go down, but fought back. T-Mobile Germany not only bans VoIP, IM and VPN usage, but also caps data on their iPhone plans.
