[asterisk-users] telco error message on PRI and BRI

[stoffell]

hello,

Since a few days I'm looking for the 'best' way to get the telco
"error" messages when dialing wrong/busy/non-existing numbers. I can't
get it to work on E1 or ISDN BRI.

An alternative option is to detect the hangup_cause (no problem here)
and play our own voice prompts. I would like to avoid this to make
sure the users experience the same behaviour as before. (with the
'traditional PBX')

I have tried changing the priindication setting (tried
inband,outofband and passthrough) but this didn't change anything.

Does anyone have any idea as to how I can debug this?

cheers,
stoffell
