• Unified CM end users for Calling in Webex App need a Mail ID, the Home Cluster checkbox, and membership of the Standard CCM End Users and Standard CTI Enabled access control groups. in context
• Automatic softphone provisioning may take up to 5 minutes to create the device and connect the user to phone services. in context
• Desk phone control of 9900, 8900, 8800 and DX phones also needs the group Standard CTI Allow Control of Phones supporting Connected Xfer and conf, and 6900 phones need Standard CTI Allow Control of Phones supporting Rollover Mode. in context
• Hybrid Calling or Webex Calling user enablement must be disabled before Calling in Webex App (Unified CM) can be enabled for a user. in context
• Webex App discovers Unified CM phone services through DNS SRV records _cisco-uds and _collab-edge, which Cisco recommends, or through manual connection settings. in context
• Without DNS SRV autodiscovery or a UC Manager Profile, users must type the UDS server address or the UC domain into Webex App themselves. in context
• Mobile and Remote Access on Expressway is needed if Webex App users must connect to Unified CM calling from outside the corporate network. in context
• A UC Manager Profile carries a Voice Services Domain, used when the sign-in email domain differs from the service discovery domain, and a UDS server, used when the Webex App user ID does not match the Unified CM user ID. in context
• A UC Manager Profile is created in Control Hub under Management > Organization Settings > UC Manager Profiles > Add Profile. in context
• When both a UDS server address and a voice services domain are configured, the server address determines the home cluster and DNS SRV autodiscovery is ignored, while the domain determines whether the client is on-premises or on MRA. in context
• For Calling in Webex App (Unified CM), the administrator creates CTI and voicemail UC services, combines them in a service profile, and assigns that service profile to the end user. in context
• Webex App softphone devices can be created automatically through Control Hub and Cloud-Connected UC, or manually in Unified CM as CSF, BOT, TCT or TAB devices with a directory number and associated user. in context
