Hello, I have an ISDN-30 connection and a Digium TE-121 with VPMADT032 echo cancellation. Every 30-60 minutes I experience PRI dropping. @@@ /etc/zaptel.conf: loadzone=dk defaultzone=dk span=2,1,0,ccs,hdb3,crc4 bchan=32-46 dchan=47 bchan=48-62 @@@ @@@ /etc/asterisk/zapata.conf [channels] switchtype=euroisdn usecallerid=yes group=2 signalling=pri_cpe context=incoming channel => 32-46

This sounds like what is happening, and is in order with what one of the technicians said - I was about 20 dB below their amplitude, theirs being 2048.

Hey, I wrote yesterday about PRI dropping, which turned out to just be a regular reset of unused B-channels. This time there's a real issue. As noted earlier I have an ISDN-30 connection, a Digium TE-121 with VPMADT032 echo cancellation. These are my configurations files: == /etc/zaptel.conf loadzone=dk defaultzone=dk span=1,1,0,css,hdb3,crc4 bchan=1-15 dchan=16 bchan=17-31 == ==

Hello, According to this page: http://bugs.digium.com/svnstats/asterisk/trunk/2006-09.html#298 a BACKGROUNDSTATUS variable was added in 2006 with revision 43814. As far as I can understand it should return different values wether the file played with a Background() command was played through or interrupted while playing. But no matter what, GET VARIABLE BACKGROUNDSTATUS returns 0. Asterisk 1.4.18.
