[Asterisk-Users] Erratic DTMF on E1/PRI (continuation of Strage bip on ISDN/PRI)

[Paulo Mannheimer]

At the same site, DTMF recognition is functioning badly, sometimes
duplicating digits and sometimes totally missing others.

We have checked already /proc/interrups, there is no interrupt being
shared.

Our zaptel has .. span=1,1,0,ccs,hdb3

On zapata we have ...
switchtype=euroisdn
signalling=pri_cpe
relaxdtmf=no (yes doesn't seem to help)

Sorry for the short post - I haven't included additional info because it
seemed irrelevant to the issue, mainly because we have already gone
through extensive trial and error.

We are using RH 7.2, testing with a cvs of 2 month ago and a fresh one
downloaded yesterday. The noise doesn't seem to follow any pattern, it
shows up once in a while. I was wondering if this can be a spill-off
from music on hold (mpg123).

Best regards,

PHM

Do they occur during changes in prompts or during single recorded
prompts? What revision of software are you using? What distro and
version are you on? 

Please provide lots of data when asking questions as it helps those who
would answer your question. It is easier to weed through information
overload than to send several messages asking for more information.
