Ericsson and Siemens Interoperate Push-to-Talk Handsets

Ericsson and Siemens Communications have successfully completed interoperability tests between Siemens push-to-talk handsets and Ericsson infrastructure (IMS system including push-to-talk server). This major step will significantly expand the customer base for operators planning to offer standards-based push-to-talk and will give consumers a simple and seamless push-to-talk experience. In addition, it shows the two global mobile communications suppliers' commitments to open standards.

Now we just need Nextel to get on board the interoperability train and then we can have a three-fold increase in the number of "push-to-talkers" that can not only interoperate & communicate, but this will probably result in a three-fold increase in how much these "push-to-talkers" irritate the hell out of me! See my Voiceglo's Nextel-like push to talk VoIP feature blog entry for details on why Push-to-Talkers irritate me.
