I am trying to know the meaning of show voice port summary. I got the following output from one router and I need to know why it is like this?
PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC
=============== == ============ ===== ==== ======== ======== ==
0/0/0 -- fxo-ls up down idle off-hook y
0/0/1 -- fxo-ls up up idle off-hook y
0/0/2 -- fxo-ls up down idle off-hook y
0/0/3 -- fxo-ls up down idle off-hook y
As you can see the status of admin is down and I think the cause is shut down command under the port, but the problem is it is off-hook so how it is off-hook and its admin status down?
my customer told me that many times the ports are hanging and they are not able to send or receive calls.
Any body face this before?
Is there any case for Admin down rather than shut down command?
what is the most important thinks that I should look for if the ports are hanging?
