How to check if an Analog Phone is connected to a VG224 Port?

How to check if an Analog Phone is connected to a VG224 Port?

Recently, I was troubleshooting an issue with VG224 where a user reported that the Analog Phone is not working. I checked in the gateway and the configuration looked correct. So, decided to ring the Analog Phone using PSTN line and checked on the gateway that the line is ringing but the analog phone is not.

Then I asked the local site contact to replace the Analog Phone with another working phone but still the issue was not resolved. When I asked the local site contact to check the analog port and connection, they mentioned that there is no issue with the lines etc.

So, finally I had only thing left in my hand is to prove if the Analog Phone is connected to VG224 or not. So, after searching  few Cisco documents I found out the command which could provide if an Analog Phone is connected to the port or not.

What is needed?

You would need to shut down the voice-port which you need to test if an Analog Phone is connected to that port or not. Let’s assume that there is a problem report on the port 2/2, you would need to shutdown the port 2/2.

VG224#configure terminal
VG224(config)#voice-port 2/2
VG224(config)#shutdown
VG224(config)#end
VG224#
VG224#test voice port 2/2 line-test phone-detection
 measured result 0x73738
 AC current = 19 uA
 measured result 0x85D47
 AC current = 22 uA
 measured result 0x79506
 AC current = 20 uA
 measured result 0x89295
 AC current = 20 uA
 measured result 0x7A624
 AC current = 20 uA
 port 2/2 may not have phone connected to


To ensure that our testing is accurate, we tested with another port on a different VG224 where Analog Phone was connected and working;

VG224#configure terminal
VG224(config)#voice-port 2/0
VG224(config)#shutdown
VG224(config)#end
VG224#
VG224#test voice port 2/0 line-test phone-detection
 measured result 0x20C48FB
 AC current = 0421 uA
 port 2/0 has phone connected to

 

So, by showing this I was able to prove that there could be a problem in the connectivity from the jack where Analog Phone is connected till Distribution panel or could be a problem from Distribution panel till VG224. So, asked the local team investigate this further.
