Hi,<br><br>I have a system with the following configuration:<br>- Asterisk 1.6.0.3-rc1<br>- DAHDI Linux 2.1.0.4<br>- DAHDI Tools 2.1.0.2<br>- wanpipe-3.3.15<br>- Sangoma A108E card with ISDN PRI interfaces<br><br>Calls arrive over the PRI interface and users need to supply DTMF digits before asterisk decides what to do with the call. The DTMF digits are read with the Read application.<br>
<br>With low call volumes everything works perfectly. However, with call volumes of more 40 calls I get a large number of DTMF errors, where a digit is detected more than once. For example, with I send the digits 0123456789, Read receives 001112345567899. The digits are are duplicated change on each attempt. I tried relaxdtmf setting chan_dahdi.conf to "yes" and "no" and there is no difference.<br>
<br>Can someone help me with this problem or is this a bug?<br><br>Thank you,<br>AC<br><br>
