• On a VG410 registered to Webex Calling, if the vDSP application is not in Running state in show app-hosting list, the fix given is voice vdsp remove followed by voice vdsp install. in context
• For a VG4xx port to register to Webex Calling, the assigned user's or workspace's extension must have at least 4 digits. in context
• For VG4xx ports connected to a fax machine on Webex Calling, the guidance is to enable T.38 to override the default audio codec. in context
• FXO and ISDN interfaces on VG4xx gateways are not currently supported for use with Webex Calling; only FXS ports are. in context
• If a VG4xx port does not register after it was changed while in use, Webex Calling guidance is to push the configuration from Control Hub again once the port is idle. in context
• Webex Calling's VG4xx article lists IOS XE 17.18.1a images (vg400-universalk9, vg4x0-universalk9 for VG410, vg420-universalk9) as the supported firmware, and requires IOS XE 17.16.1 or later for site survivability. in context
