FXO port status on desk phone

[tarek issa]

Hi,

is there a Cisco service or 3rd party service that enables us to see on the desk phones which FXO/PSTN lines are used and which ones are available.

Not aware of any 3rd party or Cisco out-of-the-box solutions.

It may be possible to develop a custom application to do this (using IP Phone Services for the phone display, and the Serviceability 'Perfmon' API for checking FXO ports active (see the 'Cisco CallManager' object and FXOPortsActive/FXOPortsInService/FXSPortsActive/FXSPortsInService counters)
