The UC300 will not support this today. The UC500 will allow you to do this, with the slight difference that extension dialing between sites is performed with the adition of steering digits to select the remote site.
Understand the desire for the feature - we get this request a lot. It is something that is being worked on at the moment, and hopefully we will have at least part of it in a firmware update sometime in the first half of next year. Support for remote phones and remote sites is something that is likely to happen in stages over a couple of firmware updates, and it's still a little too early to be able to say definitely when it will get done and exactly what it will look like. We'll try and keep everyone updated through our regular roadshows and the like as the situation develops.
thanks for your explanation. Unfortunally I'm preparing a project now and I need this feature. Is there any case study, documentation or other else for deploying such kind of project with UC500 series appliances?
