Hi,
You should be able to use the command "compand-type u-law|a-law" under the
voice port configuration, I'm sure you can check the existing configuration
by a "show voice port", I don't have the kit in front of me to check this as
I'm waiting for some memory but if I remember rightly when checking a voice
port you don't use the "-" between voice and port like you do when your'e
configuring (might be wrong). However I think the reason why you can't see
the command is because youre configuring an analog interface and I'm pretty
sure that the companding type configuration is only required for digital
interfaces.
Thanks,

Guys, just pulled this from the CD......for a Cisco 800
Question is,
How do you determine if an FXS uses alaw or ulaw on a 2600 router? Can you
set it, how do you display it?
The only thing I can find uner the voice-port 1/0/0 command is cptone?
Many thx indeed,
Ken
alaw and ulaw
Specifies the pulse code modulation (PCM) encoding scheme for telephones,
fax machines, or modems connected to a Cisco 800 series router. The keywords
are as follows:
alaw-Specifies the ITU-T PCM encoding scheme used to represent analog voice
samples as digital values.
ulaw-Specifies the North American PCM encoding scheme used to represent
analog voice samples as digital values.
The default depends on the country chosen in the pots country command (on a
cisco 800)
