Yesterday, Daniel-Constantin Mierla reported on the OpenSER mailing list that OpenSER is being used in the Cisco® Service Node for the Linksys® One family of products. Greg Fausak of Cisco confirmed this report and posted the following:
> I guess the cat's out of the bag! We've been using OpenSER for quite some time. I'm very happy with it's performance and flexibility. New features are introduced quite quickly without creating a big unstable mess. The performance is very good, we are able to route and account for calls predictably.
>
> One of my favorite things to do around here is to watch the traffic labs stress the call routing implementation. We are able to sustain 60 call per second and burst to 200.
Wow, that is pretty strong endorsement for OpenSER! We were first introduced to SER (SIP Express Router) two years ago by our carrier customers. As I wrote last week about Asterisk, open source software is having a major impact on telecom carriers. If you are in the telecom business and you do not include open source software as part of your implementation strategy, then you are competing with a serious cost disadvantage. While SER and OpenSER do not have the brand reognition Asterisk has, they are both widely deployed with carriers. The number of serious carriers using SER and OpenSER is remarkable, but few will admit to it in public.
It is nice to see Cisco be transparent about their use of open source. A full description of the Cisco Linksys Service Node is available at http://www.cisco.com/en/US/products/ps7194/products_data_sheet0900aecd805c3cc1.html

TransNexus in Asterisk Pavilion at Spring VON
For me Asterisk is one of the most interesting and exciting developments in the world of VoIP. It has been fascinating to watch Mark Spencer grow Asterisk from a little known open source project into a market force that is changing everything in telecom. Sure, the naysayers always tell you Asterisk won't scale, its not stable, the SIP stack is lousy, and on and on ..... They reality, however, is that Asterisk is getting better and better all the time. OK, Asterisk is not carrier grade now, but it will be - probably sooner that anyone expects. If you are in the telecom business and think Asterisk is a gimic that will not impact your business, you are either a dinosaur or a strategic planner working for an ILEC.
We first started working with Asterisk three years ago after hearing about Asterisk from customers. Since that time, I have been amazed by the number of Asterisk deployments. Just about every customer we have is using Asterisk or evaluating Asterisk. Only Cisco routers and Intel chips have greater penetration in the telecom marketplace. At Fall VON in 2006, a long time friend who is a product manager with a major VoIP equipment provider told me that they ship 30,000 SIP phones or ATAs to Asterisk users each month. 30,000 is a big number from a firm that is not an Asterisk partner and has a PBX solution that competes directly with Asterisk!
From my oberservations, Mark Spencer is a pretty shrewd businessman. Now that he has reorganized Digium and added outside capital, the market impact Asterisk is having will accelerate. We first exhibited with Digium in the Asterisk Pavilion at Spring VON 2005 and we are excitied about being part of the Asterisk Pavilion again this year at Spring VON 2007 in San Jose.

OSP Toolkit now on SourceForge
I am pleased to post that TransNexus has completed the transition of moving the OSP Toolkit project from SIPfoundry to SourceForge (http://sourceforge.net/projects/osp-toolkit). We appreciate our relationship with SIPfoundry and value the good work they do promoting SIP. However, we decided to move the OSP Toolkit project to SourceForge since OSP serves an audience broader than SIP users. OSP has been deployed in global wholesale H323 networks since 2000 and the number of SIP networks using OSP exceeded H323 networks in 2006. But OSP is also useful with other protocols such as IAX, jabber and any peer to peer IP communication application that requires secure authorization and accounting. So we decided to move the OSP Toolkit to SourceForge where we also host the RAMS OSP test server and the GKTMP-OSP interface.
