If you've been following my blog for a while you've probably noticed my support for Voice over LTE via GAN, or VOLGA for short. In case not and you are interested here's a link to a short intro and here a link to a whitepaper which I've recently written on the subject. It looks like the VOLGA forum has not been idle over summer and has continued working on the final stage 3 specification that contains all the nitty gritty details on messages, information elements, etc. Now in September 2009, the final version has been published which means all documents are together now to implement VOLGA. For the details, see here. Well done, I am looking forward to seeing the first implementations!
