We've got a 2651 with four FXO ports in it. PSTN callers complain of low volume. The command reference says the default output attenuation on an FXO port is 0, but our ports are all at 3, and I know we didn't change the setting.
Is the default output attenuation supposed to be 0 ?
I had the same problem with aour 2600, although we weren't using FXO ports. However, by setting the output attenuation to -6 (the maximum), this boosted the volume to the PSTN callers to a normal level. You may be ok with -2 for example, so you'll need to try a few of the settings out. Remember to bounce the port after making the change.
NB When i used the 'no output attenuation' command, the output attenuation showed a value of +3.
Also, check the ios you are using. There is a known bug with 12.2T releases.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
