Microsoft Office Communications Server 2007 R2 Site Resiliency White Paper

July 24, 2009

With Microsoft making increasing inroads with their Office Communications Server 2007 R2 platform, many integrators, VARs, and end-user customers are looking to find out more information on bringing the famed "five nines" (99.999%) of reliability to OCS 2007 R2.

Well, Microsoft has just released a white paper detailing how to ensure high reliability. According to Microsoft:

Using backup and restoration procedures for site disaster recovery as described in the Microsoft Office Communications Server 2007 R2 documentation library topic Backup and Restoration, can entail some downtime for users."

This white paper describes a site resiliency solution for Office Communications Server 2007 R2. The solution includes an Enterprise pool that spans two geographically separate sites.





Microsoft OCS 2007 R2 XMPP Gateway?

July 24, 2009

I came across a Microsoft page that lists "OCS R2 XMPP Gateway" with a General Availability date of 9/28/09. Very interesting. This would enable for example Google Talk (XMPP) users to instant message (IM) OCS users. Jabber XCP has a "SIP/SIMPLE gateway"  as well, but I would assume a Microsoft OCS 2007 R2 XMPP gateway might feature tighter integration.

For instance, it might automatically sync the XMPP users with the OCS 2007 contact list, so any users added to the XMPP server are automatically added to the OCS 2007 contact database, which then gets pushed out to all the OCS 2007 Communicator clients.

Next-gen iPod touch Features Mic, Video, and VoIP?

July 21, 2009


Wired
is reporting rumors about Apple preparing a new version of the iPod touch that includes a camera and microphone, which when combined with Skype for the iPod touch would negate the need for a home phone line. VoIP on an iPod touch? That's just heresy! Essentially, the iPod touch becomes an iPhone without the need for an AT&T contract.

The article then points out you can add a portable Verizon MiFi 3G wireless access point, which shares your 3G connection using WiFi to finally bring the iPhone experience to Verizon's 3G network.

Nimbuzz VoIP/IM App Has huge Apple App Store Marketshare

July 16, 2009

With yesterday's news about the new Nimbuzz for iPhone app and the launch of a Nimbuzz Mac client, I contacted Tobias Kemper, Head of Communications for Nimbuzz and asked him a question about DTMF/touch-tone support in any pending release.

Any plans for DTMF support?

Noticed when I tested it by calling my Skype for SIP account matched up to my corporate PBX that I couldn't reach my extension since there is no dialpad once the call is initiated.

I know touchtones are tricky when sent over an IP connection, which is what RFC 2833 is for. However, RFC 2833 is probably impossible for you guys to support.

However, I've found if you simulate the exact frequency tones and send that as a long tone - say 0.5s long, 99% of the time it gets transmitted just fine. Can often get away with ¼ of a second as well.







Military Suspension Plan from VoIP Providers - Who's Going to Step Up?

June 24, 2009


I received an email from a U.S. military service person asking me if I was aware of any VoIP service providers offering a "military suspension plan" which allows U.S. military members to "suspend" your contract without paying monthly fees.

Mr. Tom Keating,

I'm a current customer of Vonage, but have recently been disappointed by them. You see, being in the military, deployments do not allow us to use our regular phones, for obvious reasons.




flaphone, the Flash Web-based SIP-to-SIP & SIP-to-Skype VoIP App, Adds New Features

June 18, 2009

Flaphone has done some updates to their Flash-based VoIP application. Back in 2007 I broke the story about the first Adobe Flash-based SIP VoIP app called Flashphone, later renamed Flaphone. Flaphone is a web-based SIP softphone that uses ubiquitous Flash (Mac, PC, Linux), to enable you to make or receive calls to/from all SIP phones and SIP services, including Yahoo! Messenger, MSN Messenger, and Google Talk. You can make free web-based Flash calls to Yahoo! Messenger, MSN Messenger, and Google Talk (gtalk) users.

sipgate enters U.S VoIP Broadband Market offering free calls

June 2, 2009

Today, sipgate is launching a new free VoIP broadband phone service called sipgate one. sipgate one is similar to Vonage, Packet8, and other broadband VoIP providers, but with some additional cool features and a fairly unique pricing plan. For instance, you get a free telephone number, no set-up costs and no monthly charges or minimums.

I spoke with sipgate CEO Thilo Salmon to find out more about sipgate one.

Truphone 3.0 comes to the Apple iPod touch

June 1, 2009

Truphone today launched Truphone 3.0, a major new upgrade to its mobile VoIP application for the Apple iPod touch. Truphone 3.0 was already available for the Apple iPhone, so this release just brings the latest features to the popular iPhone touch.

IM services currently supported include Skype, MSN Messenger, AIM, Yahoo! Messenger and Google Talk. It also does free calls when in Wi-Fi to other Truphone users as well as free WiFi calls to Skype and Google Talk users. Though I would like to see 3G data support to enable VoIP over 3G.

50% of Mobile Voice Traffic Will Use End-to-End VoIP by 2019

May 5, 2009

Gartner, a respected research firm located just a stone's throw from TMC said today, "mobile VoIP poses a huge challenge for traditional mobile voice providers." You don't say? Hmm, I would have never guessed such a thing. Ok, other than stating the obvious, the research does have some fascinating points, including claiming that ore than 50% of mobile voice traffic will be carried using end-to-end VoIP by 2019 - or basically 10 years from now.

"Mobile portal voice over Internet Protocol (VoIP) offered by third-party application-based providers poses a huge and direct challenge to the $692.6 billion global mobile voice market", according to Gartner, Inc. Gartner predicts that over time traditional network-based mobile carriers face the real prospect of losing a major slice of their voice traffic and revenue to new non-infrastructure players that use VoIP.

But Gartner doesn't paint an entirely rosy picture for VoIP. Gartner said "that despite this significant potential, conditions for the rapid expansion in the use of mobile VoIP are not yet right and are not likely to become right for at least five years and perhaps as long as eight years."

Yeah, well when carriers like AT&T pull crap like forcing Apple to only allow VoIP over WiFi and not over a 3G data connection, it's no wonder why mobile VoIP growth will be stunted by anti-competitive tactics.





Free Calls on Skype

April 23, 2009

3 UK is opening up its network to allow anyone with a 3 SIM and a compatible handset to have unlimited Skype-to-Skype calls and instant messages without ever having to pay. 3UK announced that on May 1st users with a 3UK SIM and a 3-provided Skype-enabled handset will be able to use Skype for free. Additionally, previous deals for free Skype required a monthly topup of £10 on pay-as-you-go and there will be no data charges. Thus, Skype will be 100% free, subject to their fair use policy of course.
