Direct registration support was just added to the new Real Presence Trio 8800 last month as introduced in the firmware release table here.
This brief article reviews the basic requirements for each family of phones along with the few steps needed to successfully register a device.
This domain name will be setup for use as your e-mail address but also for remote web access (web workplace, outlook web access, etc).
Because we have chosen to manually configure DNS records, make sure that the chosen domain name has a record pointing to your server.The wizard is now configuring you server for remote web access and adding the domain name to your Exchange server.The secondary option is to allow for a tenant to bridge their own on-premises IP-PBX or SIP trunks directly to their online tenancy.This hybrid technology can be provided by either leveraging a small deployment of Lync or Skype for Business servers on-premises or by using the upcoming Cloud Connector.PSTN Calling simply means that the users will be assigned a real telephone number and can place and receive calls with any PSTN phone in the country or worldwide, depending on the purchased call plan.
This can now all be done with absolutely no Microsoft servers or services deployed on-premises.So we choose “I already have a domain name that I want to use.” You can choose to let the server manage your domain name, only this is preserved for a couple of domain name providers.If you would like to use this option you have to move your domain name to one of these providers.These two devices in the CX family of IP handsets include a Type A USB port and run Microsoft’s Lync Phone Edition software.At present only the CX600 and CX3000 models are supported; the CX500 is not.Some of this content has already been made available in previous articles but is revisited here for the sake of providing a single referenceable article.
