Cisco VG224 FXS Port Unknown
Cisco VG224 FXS Port shows Unknown
While working on VG224, the device shows all ports as unknown status on Call Manager.
This issue is found rarely, but you have some steps to diagnostic: network connectivity, protocol, voice ports. In my case, the VG is set as SCCP protocol, so I´m going to do some tests about it. Firstly verify the stcapp protocol. That is an easy step you must always do. In my case it was inactive.
VG224#show stcapp device summary
stcapp application state is inactive.
So I proceeded to enable it.
VG224(config)#stcapp
VG224(config)#exit
The stcapp feature allows CUCM to control analog phones through FXS ports in a Voice Gateway. The ports come back to be fine again:

As you can see there is one port as unregistered, but that´s ok, because the analog phone was disconnected.
The Cisco VG224 is updated and you can buy it when you need it. The website stills shows it hasn’t been End of Life announced.

Hi!
You wrote “As you can see there is one port as unregistered, but that´s ok, because the analog phone was disconnected.”
how do you think, is it possible some way to disable registration requests from unused analog port (when no phone is connected)?
Hello Igor,
That´s hard, because the port status works in that way.
Hello Igor,
That´s is hard, because the port status is a default conditon.
