Wow.<BR>
<BR>
I thought I had it fixed when I picked up misaligned CICs on my second <BR>
E1 port but it has not made any difference. Still there is no audio <BR>
making it back to the calling party who's called in via the SS7 link.<BR>
I did find that with 'ss7_explicitacm=yes' in my chan_dahdi.conf the <BR>
call would be answered by Asterisk and then hung up. It seems that for <BR>
the call to stay active I had to remove 'ss7_explicitacm' from my <BR>
config; but still there is no audio.<BR>
I enabled "monitor()" in my dialplan and I can hear that my test music <BR>
on hold is being played back but it is not making it to the calling <BR>
party called in on the SS7 link.<BR>
My provider sent me a document showing his channel numbers and his <BR>
assigned CICs. I then added to the document and listed my Dahdi ports <BR>
and corresponding CICs to assist with me aligning my CICs with his. So <BR>
far from what I can tell it looks fine?<BR>
Some posts seem to indicate that there may be a problem with <BR>
Asterisk-1.6.2 and that I should try Asterisk-1.6.0, or even 1.8.x? My <BR>
updated config files have been included below. I've also asked my <BR>
provider to enable the "Continuity Check" suggested by Gustavo but am <BR>
waiting for them to confirm. Your assistance is greatly appreciated!<BR>
